How to save bandwidth by lowering imessage’s image quality

If you are a heavy user of the iMessage service, which you should be if you are an iPhone user, then you would know that the service can consume a lot of your cellular data. This is because we use iMessage to communicate with our iOS and Mac friends, and with them we regularly share photos and other media files. The problem with photo sharing with iMessage is it sends the media files with their original size. This is different from WhatsApp, which compresses photos and videos before sending them.

While sending photos in their original resolution has its benefits, it also causes the Messages app to use a large amount of your limited cellular data allowance. It can also make the transfer significantly slower depending on your network connection. With iOS 10 Apple has finally solved this problem by adding a new ‘Low-Quality Image Mode‘ for iMessage.

From Settings you can enable this setting, after which your photos will first be resized to reduce their footprint and then sent to the other user. When the Low-Quality Image Mode is enabled you will be able to save tons of bandwidth when sharing media files with friends.

You can enable or disable the Low Quality Image Mode by opening Settings app and going to Messages. Then from there you can turn the toggle on to turn the mode on, or flip it to the off side to turn it off.

How to save bandwidth by lowering imessage’s image quality

The images you send in iMessage can use up precious bandwidth and space on your phone. However, iOS 10 now provides a way to reduce the size of images sent, if you don’t need a full quality photo.

Cell companies are stingy with data and most of us have a limited data plan. You can share photos and images with friends and family through iMessage in the Messages app, but there’s no need to burn up 1-2MB per shared photo or image, especially if it isn’t an image you’re going to save. The two photos in the above image look pretty much the same in the message, but the size difference between the two is noticeable, as shown below.

How to save bandwidth by lowering imessage’s image quality

Of course, if it’s a picture your recipient will want to save, print out, and frame, you’ll want to send it in full quality. But for the “look at my silly cat”-type pictures, this setting is useful.

NOTE: This feature is only for messages sent via iMessage to other iPhone users.

On the Home screen, tap “Settings”.

How to save bandwidth by lowering imessage’s image quality

Tap “Messages” on the Settings screen.

How to save bandwidth by lowering imessage’s image quality

Scroll to the bottom of the Messages screen and tap on the Low Quality Image Mode slider button to turn it on (it will turn green). Now, the quality of any images you send in iMessage will be of lower quality and smaller in size.

How to save bandwidth by lowering imessage’s image quality

There is one downside: this setting is either on or off for all messages you send in iMessage. You cannot turn it on for certain contacts, like you can choose to prevent certain people from getting read receipts from you in iMessage. So, if you want to send a higher quality photo or image to someone, turn this setting off before sending it, and then you can turn it back on when you want to send reduced size photos and images.

How to save bandwidth by lowering imessage’s image quality

iOS 10 has something called Low Quality Mode for images you send out in iMessage. When active, Low Quality Mode reduces any images you are sending out to approximately 100K. This can save you a lot of cellular data usage, especially if you’re sending out photographs you take on your iPhone.

Here’s how to activate it. Go to Settings > Messages . Now, scroll all the way to the very bottom, as shown below:

That’s it! If you want it on, flip that switch to green. If not, leave it off. When activated, your outgoing images will be reduced in size and quality. Your incoming images will not be affected.

What It Looks Like

Check out this test image I did with John Kheit’s unwitting help. The first one was sent in Low Quality Mode. The second one was normal. In-line, most people would be hard-pressed to tell the difference. I can see some data loss, but I know the image well.

If you open both images, however, the quality difference is much more noticeable. This is especially true on my 5K iMac, where the LQM image’s smaller dimensions were very apparent.

Users can now send photos iPhone in low quality mode, conserving data and battery usage via a new feature found in Apple’s Messages app in iOS 10. Here’s how to use it.

Previously, images could only be sent in their original size and resolution in the Messages app. To send lower quality or smaller photos, users had to hop over to the Mail app where you had Low, Middle, Full and Original downscaling options.

For those relying on cellular data to send original-sized photos, the data use can add up, at a rate of three to five megabytes per photo — Â and even more for a Live Photo.

But with iOS 10, a new Low Quality Mode in Messages cuts images roughly to around 100 kilobytes each. The actual size and compression of the low quality image depends on the quality and size of the original photo.

To turn on low quality image, go to Settings, then Messages then scroll down to the very bottom where there is a new option for Low Quality Image Mode.

To disable it and return to full-quality images in Messages, just follow the above directions and switch back to sending photos full size.

Thanks for posting.

I’ve always found it counter-intuitive that iMessage includes only high-res pictures, whereas email allows low-res pictures. I normally think of SMS for short (i.e., low bandwidth) content. In any case, I like that you can now control the size. Maybe in the future they’ll provide a way to control this separately for each message (vs. Settings, which controls the whole app).

christopher126

Thanks. I appreciate this. I had done it on my iPhone/iPad, but forgot to do it on my GF’s iPhone/iPad. I’ll do it, tonight. 🙂

scampercom

Why bury this option and make it a toggled “mode”? Simply ask what quality I want to send an image at the time of attachment. Some images work well at low resolution, and others require detail to be maintained. Eventually Apple will come around, I’m convinced — they got it right in Mail.app, after all — but this little stopgap seems like bad UI design.

johnny mozzarella

The workaround I have been using for years has been to take a screenshot of the photo and then send that instead of the full resolution photo.

larz2112

Thanks! This is a very useful setting I didn’t know about. I have an unlimited data plan, but I always feel guilty when I text a high-res photo to friends on limited data plans. For me, the vast majority of the time a low-res photo is all that is necessary. In my opinion, the way it should work is that the default should always be to text a low-res image, but if you force touch on it before you send, a option will pop up that allows you to select the high-res photo instead.

Instant messaging apps compress photos and videos to share them rapidly using less bandwidth. Compressing the images also ensures the recipient can download and view them as soon as possible, even on slow networks.

For most cases, media compression is great. But if you ever want to send an image of a document, text, group picture for printout, or any other serious purposes, you might want to stick with the highest resolution. If you don’t, the final image can be blurry, unclear, unprofessional, and with finer details lost.

To address this, here are several ways to send a picture or video clip in full, uncompressed quality on iMessage, WhatsApp, Telegram, and Signal from your iPhone or iPad.

How to send images in high quality on iMessage

Here are the quick steps to ensure pictures are sent in excellent resolution via iMessage:

1) Open the Settings app on iPhone, iPad, or iPod touch.

2) Scroll down and tap Messages.

3) From the bottom, turn off Low Quality Image Mode.

How to save bandwidth by lowering imessage’s image quality

Now, the images you send on iMessage will not be of lower quality. This will obviously take more time and data to send. But if you want the finest image quality, this is the way to go. If you ever feel like reverting this change, follow the same steps to enable low-quality images.

How to send images and videos in full quality on WhatsApp

When you send a picture or video clip, WhatsApp will identify it using the extension (.jpg, .heic, .png, .mp4, etc.) and then compress it so that it’s uploaded, sent, and downloaded quickly.

But if you send an image as a document, WhatsApp’s compression tools won’t touch it and send it in original quality at the full size. It won’t even convert HEIC images (image type iPhone Camera uses by default) to JPG.

To achieve this, you’ll have to first add the picture from the iOS Photos app to the inbuilt Files app. After that, you can select and send it as a document. If you have the images in Drive, Dropbox, OneDrive, etc., allow them to be shown in the Apple Files app.

Here are all the steps to send an image in original, uncompressed quality, file size, and format on WhatsApp for iPhone:

1) Open the Photos app and go to an album or the Recents section. From here, tap Select and choose one or more photos. Next, tap the share icon > Save to Files > choose any location > Save.

How to save bandwidth by lowering imessage’s image quality

2) Open WhatsApp and go inside a person or group chat. From here, tap the plus icon > Document. Now, tap Browse and navigate to the folder where you had saved the images in step 1.

How to save bandwidth by lowering imessage’s image quality

3) If you have to send one image, tap it and hit Send.

How to save bandwidth by lowering imessage’s image quality

4) If you have to send multiple images, tap the ellipses icon > Select > choose several photos and tap Open. Finally, tap Send.

How to send images in high quality on Telegram

Here are the steps to send pictures in full quality using Telegram on iPhone:

1) Open Telegram and go inside a person’s chat, group chat, or channel.

2) Tap the paper clip icon from the bottom left and choose File > Photo or Video.

How to save bandwidth by lowering imessage’s image quality

3) Tap an image and hit the arrow icon.

How to save bandwidth by lowering imessage’s image quality

4) To send multiple images, tap inside the small circles to select several photos and tap Send.

How to save bandwidth by lowering imessage’s image quality

Another quicker way is to tap the paper clip icon, and from the top of the slide-up, tap the small circle and choose Send as File.

How to save bandwidth by lowering imessage’s image quality

In addition, you can also follow the same steps as WhatsApp to send the image in full quality. To do this, tap the paper clip icon > File > iCloud Drive.

How to send high quality images on Signal

Here’s how to send all photos in excellent quality via the Signal app on iPhone:

1) Open the Signal app and tap your profile picture from the top left.

2) Tap Data Usage.

3) Tap Sent Media Quality and choose High.

How to save bandwidth by lowering imessage’s image quality

If you want to send high-quality images on a per case basis, open the chat > plus icon > select the image > tap the image icon from the bottom left and choose High.

How to compress images as a ZIP file and send in full quality

Using the Files app or other third-party apps from the App Store, you can turn several images and videos into a nice ZIP file.

After that, simply send this ZIP file using WhatsApp, Telegram, Signal, or iMessage.

The recipient can easily unzip the file on their Android or iOS device. If they need help, send them our article that shows the steps to unzip files on iPhone and iPad. Once they open the ZIP file, they will see all images and videos in full, original quality.

Send the image, album, or folder link to share pictures in full quality

Finally, one more option is to upload your photos and videos using your iPhone or computer to online storage services like Google Drive, Google Photos, Dropbox, One Drive, iCloud Drive, etc.

After uploading, share the link to that file, folder, or album with the person via iMessage, WhatsApp, Telegram, Signal, email, or any medium you like.

The recipient can view the full quality images and download them (depending on the permissions supported by the service and set by you.)

Placing Images on Curved Surfaces Through Displacement Mapping

By the Cloudinary Team

Say, you want to place a two-dimensional image on a curved surface, such as a mug or bottle, to create a product mockup or highlight printing capabilities. Thanks to Cloudinary’s displacement-mapping feature, that’s easy to do. Here’s how displacement mapping works. By means of a map image, the algorithm displaces…

Texting is one of the best modern tech conveniences around. Instead of fussing with a phone call, you can simply compose your messages and send them any time. You can keep them short and sweet or long and strong. You can even spice them up with photos, GIFs, emojis, animojis and videos.

You don’t even have to read a text message right away. Simply save it for later then read and reply on your own time; this is why so many people prefer texting. But did you know you can take your texting game to even greater heights?

With a few tricks, you can become a texting guru. One way is to control your phone with your voice without using Siri. Tap or click here to see how. But what else can you do? Here are the iPhone texting tricks you wish you knew all along:

1. Turn your finger into a mouse

Our iPhone screens are pretty small compared to our hands. Even the larger devices can make tapping the right place in a message tricky. Instead of frustrating yourself while trying to tap on the right word, just use this simple trick to turn your finger into a mouse.

When you’re texting someone and want to go to a specific part of the message, press and hold the space bar, then drag your finger up, down, left or right to put the cursor exactly where you want it.

2. React to messages

Do you like the reaction options social media sites offer? It’s convenient to convey your feelings with a heart or thumbs up. And now, you can react to text messages on your phone, too.

Just press down on the message and choose how you’d like to react.

How to save bandwidth by lowering imessage’s image quality

3. Quick copy and forward

If you hate group texts, but have something you want to share with multiple people, here’s a convenient shortcut. Instead of manually copying and pasting a message over and over again, forward it with a few taps.

Simply long press a message, tap More…, choose which one(s) to forward, then select the arrow on the bottom right corner to forward it. The original message’s content will be copied as a new message so all you have to do now is select the recipient(s) and send.

How to save bandwidth by lowering imessage’s image quality

4. Share your location

If you’re planning on meeting up with anyone, or you want to update someone of your location while you’re traveling, you can easily share where you are. This feature can also be useful for tracking your kids or can even be a life-saver during emergencies.

Open Messages and choose the conversation thread you have with the person you want to send your location to. Tap their name, then the info button. The person’s details page will open. From here, tap Send My Current Location.

If you want to send someone regular updates about your location, you can tap Share My Location instead. You have the option to share for an hour, until the end of the day or indefinitely.

5. Save data with lower quality images

Sending photos via text messages can be data-intensive. And if you have a mobile data cap, you can eat through it in no time. To save bandwidth, try sending low-quality photos.

To do this, go to Settings >> Messages >> then scroll all the way down and toggle Low Quality Image Mode to On.

6. Single text alerts only

iPhones will send you two text notifications in a two-minute interval by default. While this is great for those of us who forget we received a text, others may find it redundant.

To have your iPhone send single text alerts:

Go to Settings >> Notifications >> Messages. Scroll down to Repeat Alert and set it to Never. From here, you can also choose to receive up to ten alerts at two minute intervals.

7. Mute group message alerts

If you’re part of a texting group, the constant alerts can get overwhelming. Thankfully, you can silence these group alerts on your iPhone.

Open the group chat and tap the group icon at the top. Choose the info button and scroll down to Hide Alerts. Toggle it on and that’s it!

While scrolling through your messages, all group chats with hidden alerts will show a moon icon to the left.

8. Label your groups

Here’s another handy tip. If you have multiple group message threads, you can find them at a glance by naming them.

Note: This is only an option for iMessage groups.

Simply open the conversation thread, tap the names, then the info button and choose Enter a Group Name.

9. Assign individual special message tones

Want to know who’s texting you without having to look at your phone? Set special text tones for specific contacts.

Open the Contacts app and choose the person you want to customize. Tap Edit >> Text Tone. Select the tone you want.

10. Block people

Do you have contacts you don’t want to speak to anymore? Maybe they always send you unnecessary and annoying texts or just don’t respect your requests to leave you alone. To stop their messages, you have to block them from being able to contact you at all. Here’s how:

Open Contacts and look up the person you want to block. Scroll to the bottom of their information page and choose Block this Caller. Tap Block Contact to confirm. If you change your mind later, you can unblock them by looking them up from the Contacts app again and scrolling down to choose Unblock this Caller.

11. Hide notification previews

Text notification previews are convenient but anyone can read your texts from the lock screen.

If you want to keep your text previews hidden, go to Settings >> Notifications >> Messages, then scroll down to Show Previews. You can choose to receive previews When Unlocked or Never.

12. Record and send a voice message

Don’t have time to type a long message? No problem. Save time by recording a voice note using Messages.

Note: You can only do this for other iMessage users.

Launch the Messages app and start a conversation. Tap and hold the microphone button and release it when you’re done recording. Next, just send it by tapping the up arrow button.

How to save bandwidth by lowering imessage’s image quality

By default, iMessage on the iPhone and Mac show the sender when you’ve read a message. That can be handy sometimes, but not always. The good news is that the feature is easy to turn on and off.

The Messaging app on iOS and Mac devices is capable of sending and receiving two types of messages: text messages, which use your carrier’s SMS system, and iMessages, which are instant messages sent using your data connection. iMessage requires that both the sender and recipient are using an iOS or Mac device, and that a data connection is available. iMessages offer a few features that text messages do not, such as being about to see when someone is typing you a message, better group messaging, and, yes, read receipts. If you prefer that people not know when you’ve read their iMessages, we’ve got the fix for you.

Disable Read Receipts for iMessage on the iPhone

On the iPhone, you can disable read receipts for everyone, or for specific contacts (if you’re using iOS 10).

For Everybody

As with most things iPhone, you’ll disable iMessage read receipts using the Settings app. In Settings, scroll down and tap Messages.

How to save bandwidth by lowering imessage’s image quality

On the Messages screen, tap the “Send Read Receipts” switch to toggle the feature on or off.

How to save bandwidth by lowering imessage’s image quality

For Specific Contacts

What if you turn off read receipts wholesale, but still want one or two individuals to see that you’ve read their message? iOS 10 will allow you to turn on (or off) read receipts on a per-message basis. To do this open any message thread in Messages and tap on the “i” in the upper-right corner.

How to save bandwidth by lowering imessage’s image quality

Then you can turn read receipts for each individual message on or off according to how you have them set globally.

How to save bandwidth by lowering imessage’s image quality

When you disable read receipts, people who send you iMessages will still see a status when a message has been successfully delivered, but they will no longer see that you have read the message.

Keep in mind that while you can individually select who exactly you turn on read receipts for, it’s possible for the global read receipt toggle to still be turned on. This means that whenever you add a new contact to your iPhone, read receipts will automatically be enabled for them if they also have an iPhone.

The only way to keep this from happening is to turn off the global toggle in the settings. Doing this will disable read receipts for everyone, so you’ll have to go back in and re-enable them individually for the contacts you want them turned on for.

Disable Read Receipts for iMessage on the Mac

The Messages app in newer versions of Mac OS X also support the iMessage protocol. It’s similarly easy to turn off read receipts in the Mac Messages app, and just like iOS, you can do it for all contacts or certain contacts (if you’re running macOS Sierra).

Note that if you use both your Mac and iOS device to read messages, you’ll need to disable read receipts in both places.

For Everybody

In the Messages app on your Mac, click Messages on the Apple menu and then click Preferences. In the Preferences window, switch to the Accounts tab.

How to save bandwidth by lowering imessage’s image quality

On the Accounts tab, select your iMessage account on the left and then, on the right, disable the “Send read receipts” check box. You can then close the Preferences window.

How to save bandwidth by lowering imessage’s image quality

For Specific Contacts

On macOS Sierra, read receipts can be enabled or disabled on a per message basis. Just open any message and click “Details” in the upper-right corner.

How to save bandwidth by lowering imessage’s image quality

Then enable or disable “Send Read Receipts”. Again, whether this option is already checked or unchecked will depend on how read receipts are configured globally.

How to save bandwidth by lowering imessage’s image quality

With read receipts disabled, you can now read messages whenever you want without feeling the extra pressure to reply right away. And if like having read receipts enabled most of the time, it’s easy enough to disable them temporarily if you want to read a particular message without people knowing. Enjoy!

How to send high-quality photos through WhatsApp without compression?

Clicking precious moments of your life depends on the megapixels your phone’s camera, how well skilled you are and certainly the utmost precision considering lightning, contrast, background, and other features play an important role.

However, those high-quality photos get reduced in picture size and quality when they are shared by WhatsApp. This results in blurry or pixelated image and can ruin those special moments. Those images definitely cannot be set as a WhatsApp profile photo or a WhatsApp DP image. Nor can they set as a wallpaper displayed on your smart TV or printed out.

As to why WhatsApp acts as an image compressor is not known but it can be assumed that it wants to reduce the bandwidth of the users or reduce the load on their servers and in turn, reduce the time taken for sending and receiving images. Though these reasons can be justified the fact is that the users lose image quality in a shared WhatsApp photo.

There are always a few other options of sharing the photos through other mediums like email or certain Bluetooth apps to avoid WhatsApp image compression. But, did you know that uncompressed images can also be sent through WhatsApp? There are a few simple techniques that one can be used to share high-quality photos through WhatsApp.

Simple ways to avoid WhatsApp Image Compression

Method 1. Attach the photo as a document on WhatsApp.

This method is quite simple but will consume more bandwidth and time as the images do not pass the WhatsApp compression filters original photo will be transferred.

The steps to be followed are:

Step 1. Open the contact to whom you want to send the photo.

Step 2. Click on the paper clip icon at the bottom of the WhatsApp screen. Do not choose the ‘Gallery’ option which you normally do to send the images. Instead, tap on the ‘Document’ option.

Step 3. A list of the contents of your default Document folder will be displayed. Click on the option on the top that is labeled as ‘Browse other docs…’

Step 4. It will now enable you to browse through your phone. Locate the image you want to send and tap on it.

How to save bandwidth by lowering imessage’s image quality

Step 5. It will display a prompt on the screen, confirming your action. Click on Send.

Note: As the high-quality photos are sent as a document, the WhatsApp photo size compressor will not reduce the picture size even by 1%. But you will also not be able to get a preview of what images you have sent.

How to save bandwidth by lowering imessage’s image quality

Method 2. Create a compressed zip file

If the previous method to avoid WhatsApp image compression was too annoying in carrying out all those steps for one image, then compressing all the high-quality photos into a single .zip file is another easy way.

Step 1. Open the folder where you have stored the images through your File Manager app.

Step 2. Choose all the photos you wish to send and click on the three dots on the top-right of the screen.

Step 3. Click on the option that could be labeled as ‘Compress’ or ‘Archive’.

Step 4. A new file would be created with all your photos into it. Follow all the steps in the first method listed above and send the file to your family or friends.

Note: This will save time and effort while sharing many files and send all of them by following the steps once. It will also not reduce picture size as the zip file will not be considered in WhatsApp compression algorithm. The only limitation is that the receiver will have to unzip the files before being able to view them, which is a very simple process.

Method 3. Share the link to cloud storage service.

The most modern of all methods is to upload your photos on a cloud backup service like Google Drive, OneDrive or DropBox and get the shareable link. This link can then be shared by WhatsApp and the receiver can view and download those images. This method does not require any effort to be applied from the sender or receiver and there will no WhatsApp image compression applied on those images as they did not use WhatsApp as the transfer medium.

How to save bandwidth by lowering imessage’s image quality

Method 4. Rename the image file.

Another method to send high-quality photos so that it can be used as WhatsApp profile photo or WhatsApp DP images is to rename the original image file and send it as an attachment over WhatsApp. The receiver will, of course, have to rename it back to be able to view the image. It is an efficient way to send secret photos that you want to share with someone and don’t want others to know. The method is quite simple and involves a few steps:

Step 1. Long tap on the image in the file manager app and click on the three dots on the top-right of the screen.

Step 2. Choose ‘Rename’ and change the last three letters of the name after the period or dot.

Step 3. The last three letters would be ‘JPG’ in most of the cases which is the default extension for an image file. Change it to ‘PDF’ which is the default extension for an Acrobat document and attach the file in WhatsApp through the paper clip option. Send the file to your contact.

Step 4. The receiver will have to change the extension back to JPG to be able to view the image.

Note: This method is time-consuming and requires an effort but is a full proof plan to avoid WhatsApp image compression and transfer high-quality photos.

To conclude, it is an alarming matter with regards to the WhatsApp Image Compression Algorithm reducing the picture size of our artistically clicked high-quality photos and delivering a compromised copy to our contacts. However, the above methods can help avoid this limitation of WhatsApp photos and ensure that you can share the original images with your family and friends. On second thought, WhatsApp can also be used as an online image compressor tool which can help you to reduce picture size of your images for free.

What does TinyPNG do?

TinyPNG uses smart lossy compression techniques to reduce the file size of your WEBP, JPEG and PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!

Why should I use TinyPNG?

PNG is useful because it’s the only widely supported format that can store partially transparent images. The format uses compression, but the files can still be large. Use TinyPNG to shrink images for your apps and sites. It will use less bandwidth and load faster.

Can anyone tell the difference?

Excellent question! Let me give you a side by side comparison. Below are two photos of my cousin. The left image is saved as 24-bit PNG directly from Adobe Photoshop. On the right is the same image processed by TinyPNG. Spot any difference?

How does it work?

Excellent question! When you upload a PNG (Portable Network Graphics) file, similar colors in your image are combined. This technique is called “quantization”. By reducing the number of colors, 24-bit PNG files can be converted to much smaller 8-bit indexed color images. All unnecessary metadata is stripped too. The result better PNG files with 100% support for transparency. Have your cake and eat it too!

In the above image the file size is reduced by more than 70%. I have excellent eyesight but can’t spot the difference either! Use the optimized image to save bandwidth and loading time and your website visitors will thank you.

Is it supported everywhere?

Excellent question! The files produced by TinyPNG are displayed perfectly on all modern browsers including mobile devices. Still need to support Internet Explorer 6? It normally ignores PNG transparency and displays a solid background color. With TinyPNG the background becomes transparent again. Binary transparency without any workarounds!

Is it safe to use animated PNG?

Excellent question! Chrome, Firefox, Safari and now Microsoft Edge all support APNG. Only Interned Explorer does not support the format yet.

Apple added animated stickers to iMessage with the release of iOS 10. If you want to create and compress stickers under 500 KB take a look at the iMessage Panda sticker example on Github.

What about Photoshop?

Excellent question! Only Photoshop CC 2015 or newer can save images as indexed PNG files with alpha transparency. With other versions it is impossible and Photoshop CS5 cannot even display them properly.

You can use Save for Web to export your images as 24-bit transparent PNG files and upload them to TinyPNG. We’ll convert them to tiny indexed PNG files. You can also install the TinyPNG Photoshop plugin. It allows you to scale, preview and save compressed PNG and JPEG images straight from Photoshop.

Q. How do I make sure I am sending a photo at the highest possible resolution when I attach it to an email message on my phone?

A. Before you send the photo, check the image-size settings when you attach the image to the message so you know you have selected a high-resolution picture. If you pick a low-resolution photo from the start, that is what your recipient will get.

To help those with slow connections, limited-data plans or internet provider limits on attachment size, some mobile email apps can reduce the size of a photo attached to a message that’s going out. Choosing the “small” or “medium” size scales the image down, but also reduces the resolution when it arrives at its destination. Smartphone apps vary, but some can automatically resize photos, so check your default settings.

The “large,” “original” or “actual” sizes you may see on the menu create a larger file attachment and take longer to send. However, the recipient gets the photo at a higher resolution. Once the photo is attached to the message, you should see the file size displayed.

As for images attached to text messages, some wireless carriers might compress photos sent by SMS or with certain messaging apps. Some software, like iOS 11 for the iPhone, have an optional setting to automatically reduce the size of images sent with the iMessage service to lower bandwidth consumption.

Desktop email programs like Microsoft Outlook and Apple Mail can also resize photos attached to messages you send. For images that exceed your mail server’s size limits, you can also share links to the high-resolution files with tools like Apple’s MailDrop, Gmail using Google Drive or Microsoft OneDrive — services that are often integrated into your mail program to do the heavy lifting anyway. Third-party file-sharing services like Box, Dropbox and iDrive have a similar function.

The top 5 percent of data users on the Verizon Wireless network may see slower throughput speeds, the carrier announced Thursday as it began accepting preorders for the iPhone 4.

In a notice posted Thursday on Verizon’s official website, customers were informed that the carrier is implementing two new network management practices. It said that the changes will provide a better experience for its more than 94 million customers.

Verizon said that customers who subscribe to a data plan or feature on Thursday or later may see their bandwidth speeds throttled, if they use an extraordinary amount of data every month. The limits will be placed on customers who are among the top 5 percent of data users, Verizon said.

“We may reduce your data throughput speeds periodically for the remainder of your then current and immediately following billing cycle to ensure high quality network performance for other users at locations and times of peak demand,” the notice says.

“Our proactive management of the Verizon Wireless network is designed to ensure that the remaining 95% of data customers aren’t negatively affected by the inordinate data consumption of just a few users.”

Unsurprisingly, the change in policy coincides with the carrier’s upcoming launch of the iPhone 4. Both Verizon and Apple began accepting preorders for the new handset on Thursday, a purchase that requires a new two-year service contract under the carrier’s new terms of service.

Verizon is likely looking to avoid overwhelming demand from a rush of iPhone customers when the handset debuts on Feb. 10. Dropped calls and connectivity issues for iPhone users on the AT&T network resulted in a public relations nightmare at times, when AT&T was the exclusive carrier of the iPhone.

In addition to the new bandwidth throttling methods for the most active users, Verizon also announced on Thursday that it is implementing new optimization and transcoding technologies in its network to transmit data files in a more efficient manner. Through caching less data, using less capacity, and sizing video more appropriately for devices, Verizon said it hopes to streamline its network.

“The optimization process is agnostic to the content itself and to the website that provides it,” the carrier said. “While we invest much effort to avoid changing text, image, and video files in the compression process and while any change to the file is likely to be indiscernible, the optimization process may minimally impact the appearance of the file as displayed on your device.”

Using your phone usually calls for access to the internet. If you’re not in a location where you can use Wi-Fi, you rely on a mobile data network to browse the web or check your social media. Mobile data, either as part of a cellular service or a pay-as-you-go plan, costs money. Unless you have an unlimited data plan, the more you use, the more you pay.

It makes sense to reduce the amount of data you use if you aren’t on an unlimited plan. Here are some tips and tricks for limiting your data usage on your mobile device.

How to save bandwidth by lowering imessage’s image quality

Restrict Background Data

Most operating systems, including iOS and Android, allow you to restrict background data with the flick of a switch in the network settings. When you restrict background data, some apps and phone services don’t work unless you have access to a Wi-Fi network. Your phone continues to function, but you reduce the amount of data being used. This is a useful option if you track your data usage and are nearing the limit of your allowance at the end of a month.

View the Mobile Versions of Websites

When you view a website on your phone’s web browser, every element, from the text to the images, must be downloaded before it can be displayed. This isn’t a problem when viewing the website from a broadband connection, but each of those elements uses up a bit of your data allowance on your phone.

Most websites provide both a desktop and mobile version. The mobile versions of browsers and browser apps always include fewer images and are lighter and faster to open. Many websites are set up to detect whether you are viewing on a mobile device and display the mobile version automatically even if you aren’t using an app. If you think you are viewing a desktop version on your phone, it’s worth checking to see if there is a link to switch to the mobile version.

Aside from the difference in layout and content, you may be able to tell if a website is running the mobile version by the presence of the letter “m” in the URL. However, this designation has declined in popularity and is rarely seen now.

Stick to the mobile version whenever possible, and your data usage will be lower.

Don’t Clear Your Cache

There is an argument for emptying the browser cache and the cache of other apps to keep your phone running smoothly. The cache is a component that stores website data. When that data is requested by the browser, having it in the cache means it is provided faster because there’s no need for the data to be downloaded from the server.

Emptying the cache frees up internal memory and helps the system run smoothly, but it consumes data when you’re on a carrier network. Task managers and cleaning utilities often delete the cache, so if you have one of those installed, add your browser to the list of excluded apps.

Use a Text-Only Browser

Several third-party browsers, such as TextOnly and Violoncello, remove images from a website and display only the text. Your phone uses less data by not downloading the images, which are the largest files on any web page.

Le immagini che si inviano in iMessage possono consumare preziosa larghezza di banda e spazio sul telefono. Tuttavia, iOS 10 ora offre un modo per ridurre la dimensione delle immagini inviate, se non è necessaria una foto di qualità completa.

Le aziende di celle sono avari di dati e molti di noi hanno un piano dati limitato. Puoi condividere foto e immagini con amici e familiari tramite iMessage nell’app Messaggi, ma non è necessario masterizzare 1-2 MB per foto o immagini condivise, soprattutto se non si tratta di un’immagine che stai per salvare. Le due foto nell’immagine sopra sembrano più o meno le stesse nel messaggio, ma la differenza di dimensioni tra i due è evidente, come mostrato di seguito.

I was wondering how to display on client side a thumbnail of an image that hasn’t been fully downloaded from a remote server yet.

For example if you send an image to a whatsApp contact.. that contact will (almost immediately) see a thumbnail of the image in low rez, and it will start downloading the pic until you see the full res image.

Now one possible scenario is that this process is broken into 4 steps:

  1. sender uploads image to whats app server
  2. whatApp creates a mini version of the img on the server
  3. whatApp sends the mini version of img to receiver, which displays quickly as a low res img, and meanwhile uploads the high res version of the img to the receiver
  4. receiver gets the high res image and views it.

what i’m trying to do is create a thumbnail view of all the attachments sent to an email client. There is no server side aspect to my app (it’s all client side).. and so I won’t be able to replicate the above process (if that were the case with whatsapp)

doing further research, three20 implements a thumbnail view of images.. the problem with this library is that each image you instantiate for the thumbnail view must specify a thumbnail URL, which is different from the full sized URL as well (see @interface MockPhoto here for example ).. so that’s a dead end as well..

This post about progressive image rendering/interlacing was interesting, but it instructs creators of images to save it in a special way, which won’t help me.

any ideas? Maybe there is a library that electively fetches information from an image via a network call?

If you regularly run into issues opening images that use the .heic extension, the easiest solution is to convert the file into a more compatible format. Using apps like Photos and Preview on a Mac makes the process simple, but macOS Monterey just streamlined the process so that you don’t even have to open an app anymore.

Ever since iOS 11, Apple has supported the HEIF image format for pictures taken with the iPhone’s Camera app. While these types of photos, which use the .heic and .heics extensions, have worked on Macs since macOS High Sierra, there are still app developers and non-Apple devices that have not fully embraced the High-Efficiency Image File Format. The new macOS 12 can help with that.

Why You Might Need to Convert HEIC to Other Formats

On an iPhone, there are two ways to capture photos from the camera — High Efficiency and Most Compatible — and you can set your preferred capture method in Settings –> Camera –> Formats. To put it simply, High Efficiency uses the .heic and .heics extension (HEIF format), depending on the number of images inside the file, while Most Compatible uses .jpg or .jpeg (JPEG format).

The HEIF format is excellent because it compresses photos into smaller file sizes than JPEG while preserving image quality. Some might even say that the image quality is better overall with HEIF. The problem is that not all software and platforms support .heic and .heics file types yet. So depending on what you plan to do with your photo (open in an app, upload to a website, etc.), you may have difficulties.

Big apps like Facebook, Twitter, and Flickr will automatically convert an HEIF file to JPEG, but not all services will do that. For example, HEIF images are not compatible with the Media Library of WordPress.com websites. Some stock photo sites may not support HEIF yet either, such as Unsplash, which requires JPEG formats (.jpg, .jpeg).

Those are just a few examples of why taking HEIF images on your iPhone could cause problems. Apple made it an option in the Camera app’s settings since HEIF support was few and far between when iOS 11 first hit, but it’s still an option, which means it’s still not universally supported. Before macOS Monterey, the main ways to avoid HEIF were:

  • Choose “Most Compatible” in the Camera app’s settings on your iPhone. This will default to JPEG format when shooting photos.
  • Choose “Automatic” in the Photos app’s settings on your iPhone. This will convert most HEIF files into JPEGs whenever you transfer them to a Mac or PC.
  • Open the HEIF file in Photos or Preview on your Mac, then choose File –> Export –> [your intended file type].
  • Use a third-party desktop, mobile, or web app to convert HEIF to other formats.

Converting HEIC in MacOS Monterey Is Easy

With macOS Monterey (version 12), there is an easier option. If you have an .heic or .heics file on your Mac, right-click or control-click the file to reveal the contextual menu. Image conversion also works with multiple files simultaneously, so if you need to convert two or more images, save time by selecting them all before opening the contextual menu.

Near the bottom of the menu, hover over “Quick Actions,” then find the new “Convert Image” option.

How to save bandwidth by lowering imessage’s image quality

If you don’t see it, select “Customize” and make sure “Convert Image” is checked in the Finder extensions list.

How to save bandwidth by lowering imessage’s image quality

Selecting “Convert Image” will bring you to a dialog box with a few options. For an HEIF image, you can convert it to either JPEG or PNG (.png) formats. You can also choose the image size to be small, medium, large, or original. For PNG, the file sizes will usually be larger than JPEGs.

There is also a checkbox to “Preserve Metadata,” which will keep image data such as location, camera details, tags, and date/time.

When ready, hit “Convert to JPEG” or “Convert to PNG.” The converted copy (or copies) will appear in the same directory the HEIF image or images were located.

How to save bandwidth by lowering imessage’s image quality

Each converted file’s name will remain unchanged aside from the file extension. If you perform a single conversation from within Finder (instead of Desktop), it gives you a chance to rename the file right away. If you do more than one, it will highlight all the files instead.

The “Convert Image” quick action can also convert other files types to JPEG, PNG, or HEIF, such as JPEG, PNG, TIFF, GIF, Bitmap, and even Google’s WebP files, but it won’t let you convert PDFs.

Aside from working with multiple file types and batch conversion, you can convert various file types simultaneously too. That means you can convert a group of images in different formats to a single format type.

“Convert Image” is an excellent addition to macOS, which will make it easier to work with and share HEIF images until the format becomes more ubiquitous.

How to save bandwidth by lowering imessage’s image quality

Les images que vous envoyez dans iMessage peuvent utiliser une bande passante et un espace précieux sur votre téléphone. Cependant, iOS 10 offre désormais un moyen de réduire la taille des images envoyées, si vous n’avez pas besoin d’une photo de qualité complète.

Les entreprises de téléphonie cellulaire sont avares de données et la plupart d’entre nous ont un plan de données limité. Vous pouvez partager des photos et des images avec vos amis et votre famille via iMessage dans l’application Messages, mais vous n’avez pas besoin de graver 1 à 2 Mo par photo ou image partagée, surtout s’il ne s’agit pas d’une image à enregistrer. Les deux photos dans l’image ci-dessus ont à peu près la même apparence dans le message, mais la différence de taille entre les deux est perceptible, comme indiqué ci-dessous.

How to save bandwidth by lowering imessage’s image quality

Bien sûr, s’il s’agit d’une photo que votre destinataire voudra sauvegarder, imprimer et cadrer, vous voudrez l’envoyer en pleine qualité. Mais pour les images de type «regarde mon chat idiot», ce réglage est utile.

REMARQUE: cette fonctionnalité concerne uniquement les messages envoyés via iMessage à d’autres utilisateurs d’iPhone.

Dans l’écran d’accueil, touchez «Paramètres».

Appuyez sur “Messages” sur l’écran Paramètres.

How to save bandwidth by lowering imessage’s image quality

Faites défiler l’écran Messages jusqu’au bas de l’écran et appuyez sur le bouton coulissant Mode image basse qualité pour l’activer (il deviendra vert). Désormais, la qualité des images que vous envoyez dans iMessage sera de qualité inférieure et de taille réduite.

How to save bandwidth by lowering imessage’s image quality

Il y a un inconvénient: ce paramètre est activé ou désactivé pour tous les messages que vous envoyez dans iMessage. Vous ne pouvez pas l’activer pour certains contacts, comme vous pouvez choisir d’empêcher certaines personnes de recevoir des accusés de lecture de votre part dans iMessage. Par conséquent, si vous souhaitez envoyer une photo ou une image de qualité supérieure à une personne, désactivez ce paramètre avant de l’envoyer. Vous pourrez ensuite le réactiver lorsque vous souhaitez envoyer des photos et des images de taille réduite.

iOS 10 has been unveiled on 13th September, as proclaimed previously at the iPhone 7 event. Despite Apple has been evaluating iOS 10 since quite a long time now but now they have launched the stable version of iOS 10, which will not have any bug or error. If perhaps you were using iOS 10 beta version, you may know that Apple has incorporated plenty of features in iOS 10 those can enhance your efficiency as well as upgrade your user experience. Having said that, if you haven’t used any beta version of iOS 10, you can now download the stable edition. But, before installing that, you should know what are you about to get with iOS 10. Consequently, what follows is a list of most imperative features that Apple has included in iOS 10.

How to save bandwidth by lowering imessage’s image quality

Bedtime Alarm

Bedtime is a very useful application or inclusion of iOS 10, which helps users to track the sleeping time. You know health is the greatest wealth and iOS 10 will take care of your most valuable asset with the aid of Bedtime. You need to setup few things to start using this feature, which is included in the Clock app for iOS 10.

Low-Quality Image in iMessage

If bandwidth is an issue of your internet browsing and you want to save bandwidth in any way, iOS 10’s iMessage app can help you for sure with the help of “Low-Quality Image.” Low-Quality Image is a imperative feature to reduce the image size (memory) dramatically so that you can see the same image but the compressed version.

Lock Screen Widgets

Android users know what lock screen widgets are. As the name defines you can find some widgets on your lock screen so that you can check different things without unlocking your device. It can be weather report, latest news, Twitter timeline or anything else. If you are always a busy person and want to do something faster, lock screen widgets may help you to do so.

Raise to Wake

Raise to Wake feature lets you check your notifications without even tapping on any physical button and even when your mobile is locked. This smart feature of iOS 10 will assist iPhone 6S and above users to check notification by just picking it up. Active Display or this Raise to Wake feature uses proximity and motion sensor to do all those things.

Suggestive Correction of Siri

Siri has now become more sophisticated with the upgrade of iOS 10. Now, you can get suggestions from Siri when you are asking for something using Siri. Previously, Siri just told you about no search result but now in most of the times, you will get something as Siri will make the correction on its own. Therefore, if you make anything wrong, it won’t be a huge problem.

Siri can Find Parked Car

If your phone’s Bluetooth of CarPlay is connected to your car, you can easily find your parked car utilizing Siri. Just ask Siri “Where is my car?” or “Find my car.” It will show you on your map. It happens because the Maps took note of when you turned off your car Bluetooth or CarPlay, and it notes that on the Map. Therefore, you can find your parked car easily.

Hide System Apps

Like other mobile platforms, iOS 10 also comes with some system apps or stock apps. Sometimes they help us or sometimes they just stay on our mobile without helping much. If you think that you do not need any stock app, you can indeed disable or hide them from the home screen. Later, you can download that from App Store whenever you need. Just tap and hold the app for a few moments until you get the -ve sign. Therefore, tap on that and hit the affirmative option. That’s it!

Night Shift

Who doesn’t get eyestrain? Everyone. If you use your mobile for a long time even in the low light area, you can easily get rid of eyestrain with the help of Night Shift. It will add a yellow layer on your existing screen to reduce the brightness and contrast so that you can get a better viewing experience. You can turn on Night Shift right from Control Center or from Settings.

Book Cab using Siri

Now Siri can book a cab for you. All you need to is just to ask her to get a cab from a particular location. Obviously, you need the cab application on your mobile. But, you do not have to open the cab app or do anything else. Just ask Siri like this,

Get a cab from X

That’s it! You can find your bookings right away.

Apple Pay + Safari = Quicker Payment

If you are using Apple Safari and want to pay somewhere, you can simply opt for the Apple Pay option, which has been included into iOS 10. Now, you do not have to enter your card details all the times. If you have set up Apple Pay, you can easily pay the money with the help of that.

There are many other features those will certainly assist you to do something quicker. iOS 10 is much more feature-rich than former versions. Just upgrade your iPhone to iOS 10 and experience all the new features.

Bildene du sender i iMessage kan bruke verdifull båndbredde og plass på telefonen. Imidlertid gir iOS 10 nå en måte å redusere størrelsen på bilder som sendes, hvis du ikke trenger et fullverdig bilde.

Cellfirmaer er gjerrig med data, og de fleste av oss har en begrenset dataplan. Du kan dele bilder og bilder med venner og familie via iMessage i appen Meldinger, men det er ikke nødvendig å brenne opp 1-2 MB per delt bilde eller bilde, spesielt hvis det ikke er et bilde du skal lagre. De to bildene i bildet ovenfor ser omtrent like ut i meldingen, men størrelsesforskjellen mellom de to er merkbar som vist nedenfor.

Die Bilder, die Sie in iMessage senden, können auf Ihrem Telefon wertvolle Bandbreite und Speicherplatz verbrauchen. Allerdings bietet iOS 10 jetzt eine Möglichkeit, die Größe von gesendeten Bildern zu reduzieren, wenn Sie kein Foto in voller Qualität benötigen.

Zellfirmen sind geizig mit Daten und die meisten von uns haben einen begrenzten Datentarif. Sie können Fotos und Bilder mit Freunden und Familie über iMessage in der Nachrichten App teilen, aber es ist nicht nötig, 1-2 MB pro geteiltem Foto oder Bild zu brennen, besonders wenn es sich nicht um ein Bild handelt, das Sie speichern möchten. Die zwei Fotos im obigen Bild sehen in der Nachricht ziemlich gleich aus, aber der Größenunterschied zwischen den beiden ist erkennbar, wie unten gezeigt.

iMessage에서 보내는 이미지는 귀중한 대역폭과 공간을 휴대 전화에서 사용할 수 있습니다. 그러나 iOS 10은 완전한 품질의 사진이 필요하지 않은 경우 전송 된 이미지의 크기를 줄이는 방법을 제공합니다.

셀 회사는 데이터가 부족하고 대부분의 사용자는 제한된 데이터 플랜을 가지고 있습니다. 메시지 앱에서는 iMessage를 통해 친구 나 가족과 사진 및 이미지를 공유 할 수 있지만 공유 할 사진이나 이미지 당 1-2MB를 소모 할 필요가 없습니다. 특히 저장하려는 이미지가 아닌 경우에는 특히 그렇습니다. 위 이미지의 두 사진은 메시지에서 거의 동일하게 보이지만 두 사진의 크기 차이는 다음과 같이 두드러집니다.

How to save bandwidth by lowering imessage’s image quality

물론 수신자가 사진을 저장하고 인쇄하고 프레임하려는 경우 전체 품질로 보내고 싶을 것입니다. 그러나 “내 어리석은 고양이를 보아라.”형 그림의 경우이 설정이 유용합니다.

참고 :이 기능은 iMessage를 통해 다른 iPhone 사용자에게 전송 된 메시지에만 적용됩니다.

초기 화면에서 ‘설정’을 탭합니다.

메시지 화면의 맨 아래로 스크롤하여 저화질 이미지 모드 슬라이더 버튼을 탭하여 켜십시오 (녹색으로 바뀝니다). 이제, iMessage에서 보내는 이미지의 품질은 더 낮은 품질과 더 작은 크기입니다.

How to save bandwidth by lowering imessage’s image quality

여기에는 하나의 단점이 있습니다.이 설정은 iMessage에서 보내는 모든 메시지에 대해 켜짐 또는 꺼짐 중 하나입니다. 특정 사람이 iMessage에서 읽음 확인을받지 못하도록 선택할 수있는 것처럼 특정 연락처에 대해서는 켤 수 없습니다. 따라서 누군가에게 고품질의 사진이나 이미지를 보내려면 보내기 전에이 설정을 해제 한 다음 축소 된 크기의 사진과 이미지를 보내려는 경우 다시 켜십시오.

Az iMessage-ben küldött képek értékes sávszélességet és helyet használhatnak a telefonon. Az iOS 10 azonban lehetővé teszi, hogy csökkentse a küldött képek méretét, ha nincs szüksége teljes minőségű fotóra.

A cellás cégek az adatokkal szembesülnek, és a legtöbbünknek korlátozott adatterve van. Megoszthatja fényképeit és képeit barátaival és családjával az Üzenetek alkalmazásban az iMessage segítségével, de nincs szükség megosztott fotóra vagy képre 1–2 MB-ra égetni, különösen, ha nem egy kép, amelyet menteni fog. A fenti képen látható két kép az üzenetben meglehetősen megegyezik, de a kettő közötti méretkülönbség észrevehető, ahogy az alábbiakban látható.

How to save bandwidth by lowering imessage’s image quality

Természetesen, ha az a kép, amelyet a címzett meg akar menteni, kinyomtatni és keretbe helyezni, teljes minőségben kívánja elküldeni. De a „buta macska” típusú képeim esetében ez a beállítás hasznos.

MEGJEGYZÉS: Ez a funkció csak az iMessage által más iPhone felhasználóknak küldött üzenetekre vonatkozik.

A kezdőképernyőn érintse meg a „Beállítások” elemet.

How to save bandwidth by lowering imessage’s image quality

Érintse meg az „Üzenetek” gombot a Beállítások képernyőn.

How to save bandwidth by lowering imessage’s image quality

Görgessen az Üzenetek képernyő aljára, és érintse meg az Alacsony minőségű kép mód csúszkát, hogy bekapcsolja (zöldre vált). Most az iMessage-ben küldött képek minősége alacsonyabb és kisebb lesz.

How to save bandwidth by lowering imessage’s image quality

Az egyik hátránya: ez a beállítás az iMessage-ben küldött összes üzenet esetében be vagy ki van kapcsolva. Bizonyos kapcsolatokhoz nem kapcsolhatja be, például úgy, hogy megakadályozhatja, hogy bizonyos személyek olvasási nyugtákat kapjanak tőled az iMessage-ben. Tehát, ha magasabb minőségű fotót vagy képet szeretne küldeni valakinek, kapcsolja ki ezt a beállítást, mielőtt elküldi azt, majd újra bekapcsolhatja, ha csökkentett méretű fényképeket és képeket szeretne küldeni.

How to save bandwidth by lowering imessage’s image qualityThe high-speed LXT cameras with integrated JPEG image compression save bandwidth, CPU load, and storage capacity for a simpler and more cost-effective system design. The new LXT cameras with integrated JPEG image compression allow image capture with very high resolution and speed via the widely available and easy-to-use GigE interface. This means, for example, that 500 frames/s with full HD or more than 1500 frames/s with SVGA can be used without any time limitations. As a result, the bandwidth, CPU load, and required storage capacity are reduced. This simplifies the system design and lowers integration costs. The cameras are optimally suited for capturing long image sequences in which original images can be compressed, transmitted, and stored, e.g., inspection of pantographs in railway, control of continuous material in paper production, analysis of motion sequences in the sports industry, or process monitoring. The first models will become available this quarter.

Thanks to the configurable JPEG compression rate, the image quality can be individually adjusted to the application. Data reduction in the range of 1:10 to 1:20 is possible. The image compression takes place directly in the FPGA of the camera, which relieves the PC-based image processing system of computing-intensive image compression algorithms. This allows several cameras to be used simultaneously from one PC via a switch. Compared to the transfer and storage of full images, applications can benefit from reduced storage capacity requirements plus the associated hardware savings.

The five new models with resolutions from 0.5 MP to 9 MP feature the latest Sony Pregius CMOS sensors of the 2nd and 3rd generation coupled with very high sensitivity with a pixel size of up to 9 µm. Short exposure times of up to 1 µs are especially advantageous for capturing very fast movements. The exceptionally high image quality with low noise facilitates reliable image evaluation, even under adverse circumstances, e.g., motion analysis for indoor sports with reduced illumination intensity.

The 10 GigE models of the LX series are the ideal choice for demanding inspection tasks that place strict demands on high-definition image quality at high throughput. Their robust industrial design withstands mechanical loads and ensures reliable image processing. The cameras are equipped with four opto-decoupled power outputs with pulse width modulation and an output performance of up to 120 W (max. 48 V / 2.5 A) for the direct control of illumination without an external controller. Thanks to the optional patented tube system, the cameras offer the protection class IP 65 and IP 67, entirely without an external housing. Equipped with Precision Time Protocol (PTP) according to the IEEE 1588 standard, the LXT models additionally support precise time synchronization in Ethernet networks. The flexible activation of objectives with liquid lenses allows simple adjustment to varying working distances. The integrated HDR function facilitates stable image capture even in difficult illumination situations, such as outdoors.

I n this tutorial, we are going to see how to increase font size in CMD. The famous cmd.exe of Windows allows increasing the size of texts for better readability on the screen. A little-known but very useful option. which is compatible with all versions of Windows: both workstation (Windows 10, 8.1, 8, 7) and Windows Server (2019, 2016, 2012 / R2, 2008 / R2 …). In short, all versions of Windows and even XP can change, up or down, the text size and font for more comfort on the screen.

It is also possible to change the colors of the text and the background of the command prompt. Some other options exist to customize the Windows Command Prompt: the size of the cmd window, the size of the buffer (number of history lines displayed on the screen). We won’t make it like a Linux Terminal but these options allow us to have a full-screen cmd, for more comfort when playing a script or analyzing traces.

How To Increase Font Size In CMD

Step 1: Click on start button and type CMD. Then click on its icon.

Step 2: In the Command Prompt, right click on the title bar and choose Properties:

Step 3: Go to the Font tab in the “Command Prompt Properties”:

Step 4: Change the Size and/or the Font, an immediate preview allows you to see the changes:

Step 5: Validate with OK and run a new cmd to see the changes:

Изображенията, които изпращате в iMessage, могат да изразходват ценна лента и пространство на вашия телефон. Въпреки това iOS 10 вече осигурява начин да намалите размера на изпратените изображения, ако не ви е необходима снимка с пълно качество.

Клетъчните компании са оскъдни с данни и повечето от нас имат ограничен план за данни. Можете да споделяте снимки и изображения с приятели и близки чрез iMessage в приложението Messages, но няма нужда да записвате 1-2MB на споделена снимка или изображение, особено ако това не е изображение, което ще запазите. Двете снимки в горното изображение изглеждат почти еднакви в съобщението, но разликата в размерите между двете е забележима, както е показано по-долу.

How to save bandwidth by lowering imessage’s image quality

Разбира се, ако това е картина, която получателят ще иска да запази, разпечата и подреди, ще трябва да го изпратите в пълно качество. Но за снимките от вида „поглед към моята глупава котка“ тази настройка е полезна.

ЗАБЕЛЕЖКА: Тази функция е само за съобщения, изпратени чрез iMessage на други потребители на iPhone.

В началния екран натиснете „Настройки“.

How to save bandwidth by lowering imessage’s image quality

Докоснете „Съобщения“ на екрана с настройки.

How to save bandwidth by lowering imessage’s image quality

Превъртете до дъното на екрана Съобщения и докоснете плъзгача на бутона за ниско качество на изображението, за да го включите (той ще стане зелен). Сега качеството на всички изображения, които изпращате в iMessage, ще бъдат с по-ниско качество и по-малки по размер.

How to save bandwidth by lowering imessage’s image quality

Има един недостатък: тази настройка е включена или изключена за всички съобщения, които изпращате в iMessage. Не можете да го включите за определени контакти, например можете да избегнете да забраните на определени хора да получават разписки от вас в iMessage. Така че, ако искате да изпратите снимка или изображение с по-високо качество на някого, изключете тази настройка, преди да я изпратите, след което можете да я включите отново, когато искате да изпратите снимки и изображения с намален размер.

Holographic rendering enables your application to draw a hologram at a precise location in the world around the user, whether it’s precisely placed in the physical world or within a virtual realm you’ve created. Holograms are objects made of sound and light. Rendering enables your application to add the light.

Device support

Feature HoloLens (first gen) HoloLens 2 Immersive headsets
Rendering вњ”пёЏ вњ”пёЏ вњ”пёЏ

Holographic rendering

Key to holographic rendering is knowing what kind of device is being used. Devices with see-through displays, such as HoloLens, add light to the world. Black pixels are fully transparent, while brighter pixels are increasingly opaque. Because the light from the displays is added to the light from the real world, white pixels are translucent.

While stereoscopic rendering provides one depth cue for your holograms, adding grounding effects can help users see more easily what surface a hologram is near. One grounding technique is to add a glow around a hologram on the nearby surface, and then render a shadow against this glow. In this way, your shadow appears to subtract light from the environment. Spatial sound is another important depth cue, letting users reason about the distance and relative location of a hologram.

Devices with opaque displays, like Windows Mixed Reality immersive headsets, block out the world. Black pixels are solid black, and any other color appears as that color to the user. Your application is responsible for rendering everything the user sees. This makes it even more important to maintain a constant refresh rate so that users have a comfortable experience.

Predicted rendering parameters

Mixed reality headsets (both HoloLens and immersive headsets) continually track the position and orientation of the user’s head relative to their surroundings. As your application begins preparing its next frame, the system predicts where the user’s head will be in the future at the exact moment that the frame shows up on the displays. Based on this prediction, the system calculates the view and the projection transforms to use for that frame. Your application must use these transforms to produce correct results. If system-supplied transforms aren’t used, the resulting image won’t align with the real world, leading to user discomfort.

To accurately predict when a new frame will reach the displays, the system is constantly measuring the effective end-to-end latency of your application’s rendering pipeline. While the system adjusts to the length of your rendering pipeline, you can improve hologram stability by keeping that pipeline as short as possible.

Applications that use advanced techniques to augment the system prediction can override the system view and projection transforms. These applications must still use system-supplied transforms as a basis for their custom transforms to produce meaningful results.

Other rendering parameters

When rendering a frame, the system specifies the back-buffer viewport in which your application should draw. This viewport is often smaller than the full size of the frame buffer. Whatever the viewport size, once the frame is rendered by the application, the system upscales the image to fill the entirety of the displays.

For applications that find themselves unable to render at the required refresh rate, system rendering parameters can be configured to reduce memory pressure and rendering cost at the cost of increased pixel aliasing. The back buffer format can also be changed, which for some apps can help to improve memory bandwidth and pixel throughput.

The rendering frustum, resolution, and framerate in which your app is asked to render might also change from frame to frame, and might differ across the left and right eye. For example, when mixed reality capture (MRC) is active and the photo/video camera view configuration isn’t opted-into, one eye might be rendered with a larger FOV or resolution.

For any given frame, your app must render using the view transform, projection transform, and viewport resolution provided by the system. Additionally, your application must never assume that any rendering or view parameter remains fixed from frame-to-frame. Engines like Unity handle all these transforms for you in their own camera objects so that the physical movement of your users and the state of the system is always respected. If your application allows for virtual movement of the user through the world (e.g. using the thumbstick on a gamepad), you can add a parent rig object above the camera that moves it around. This causes the camera to reflect both the user’s virtual and physical motion. If your application modifies the view transform, projection transform, or viewport dimension provided by the system, it must inform the system by calling the appropriate override API.

To enhance the stability of your holographic rendering, your app should provide to Windows each frame the depth buffer it used for rendering. If your app does provide a depth buffer, it should have coherent depth values, with depth expressed in meters from the camera. This enables the system to use your per-pixel depth data to better stabilize content if the user’s head ends up slightly offset from the predicted location. If you aren’t able to provide your depth buffer, you can provide a focus point and normal, defining a plane that cuts through most of your content. If both the depth buffer and a focus plane are provided, the system might use both. In particular, it’s helpful to provide both the depth buffer and a focus point that includes a velocity vector when your application displays holograms that are in motion.

Refer to Rendering in DirectX article for low-level details about this topic.

Holographic cameras

Windows Mixed Reality introduces the concept of a holographic camera. Holographic cameras are similar to the traditional camera found in 3D graphics texts; they define both the extrinsic (position and orientation) and intrinsic camera properties. (For example, field-of-view is used to view a virtual 3D scene.) Unlike traditional 3D cameras, the application isn’t in control of the position, orientation, and intrinsic properties of the camera. Rather, the position and orientation of the holographic camera is implicitly controlled by the user’s movement. The user’s movement is relayed to the application on a frame-by-frame basis via a view transform. Likewise, the camera’s intrinsic properties are defined by the device’s calibrated optics and relayed frame-by-frame via the projection transform.

In general, your application will render for a single stereo camera. A robust rendering loop will support multiple cameras, and will support both mono and stereo cameras. For example, the system might ask your application to render from an alternate perspective when the user activates a feature like mixed reality capture (MRC), depending on the headset shape. Applications that can support multiple cameras get them by opting-in to the kind of cameras they can support.

Volume rendering

When rendering medical MRIs or engineering volumes in 3D, volume rendering techniques are often used. These techniques can be interesting in mixed reality, where users can naturally view such a volume from key angles, simply by moving their head.

WinSnap allows you to save screenshots in several different image formats: PNG, JPEG, GIF, TIFF and, of course, BMP. There is no the “best for all” image format – each one has its own scope of possible applications.

How to save bandwidth by lowering imessage’s image quality

More details on the supported image formats:

  1. PNG (Portable Network Graphics) is a relatively new image format specially invented for the Web images. The main advantage of this picture format is its alpha-channel transparency support. The PNG is possibly the best choice for saving the screenshots as it doesn’t add distortions and noises due to its lossless data-compression algorithm. It is also the only appropriate image format for screenshots with shadows and reflections.
  2. JPG or JPEG (named after Joint Photographic Experts Group) features lossy image compression algorithm. On one hand it significantly decreases the size of the image, however the underside of such advantage are noises and distortions in the compressed image. JPG format is an excellent choice for digital photos, or high-color screenshots with a picture background, though it performs much worse with detailed images, or images that contain text. Also, JPG doesn’t support the alpha-channel so it is not suitable for screenshots with shadows or a transparency.
  3. GIF (Graphic Interchange Format) was initially developed in 1987 and was the major image format on the Web until the PNG development. The main advantage and, at the same time, the main disadvantage of the GIF is its low color depth. The Gif is capable of storing picture with 8-bit color only which ends up with 256 color in total. Too bad for most of the nowadays images. However, GIF has its pluses too. It is an ultimately light-weight format and is still applicable for the Web images. It also provides a very good compression for solid color images (like windows with large empty areas) and doesn’t add image artifacts thanks to lossless compression algorithm.
  4. TIFF (Tagged Image File Format) is a flexible image format suitable for holding a pack of images and data within a single file. TIFF uses a lossless LZW compression and thus can be edited and re-saved without losing image quality. TIFF is mostly used as a container to save scanned images and various graphics. It is also a de-facto standard for sending faxes.
  5. BMP (Bitmap) is a legacy image format with simple RLE compression algorithm or no compression at all. It stores images with any color depth from 1-bpp to 32-bpp. Due to lack of efficient compression algorithms, a BMP file is 10-15 times larger than the same image stored as PNG or JPG file. That is why BMP is not used on the Web and is only a compatibility format these days.

WinSnap is capable of saving any image (except images in JPG format) in 8-bpp (bits per pixel) color depth. It utilizes the smart color reduction algorithm, so there is no huge loss in the quality of the final image.

What are Suitable Image Formats to Use?

In the real life, you’ll generally choose between PNG and JPG image formats to store your screenshots. Puzzled which one you need? Both PNG and JPG are suitable for Web usage, though there are several significant differences between them.

This funny picture created by Louis Brandy clearly shows the main disadvantage of JPEG.

What PNG Is Good For?

Pros: Supports the alpha-channel, so you can use it for images with transparent background and/or translucent shadows. It uses a lossless image compression, so you won’t see visual artifacts around a text or small details of a picture. Due to that, this format is best used with screenshots.

Cons: Lossless compression isn’t very good when you need to compress a high-quality photography. A digital photo saved as PNG is 3-4 times larger (in file size) then the same image in the JPG format which doesn’t make it the right choice if you want to build a digital photo-gallery, for example.

What JPG Is Good For?

Pros: It features very good image compression algorithms, so it can reduce the size of an image in dozens of times in some cases! Thanks to that, a high-quality digital photo of a decent resolution takes very little bandwidth if put on the Web. This format is a perfect choice to upload your family photos to Flickr.

Cons: When you save an image with lot of texts or small contrast details, you can easily notice the strange noises around them – these are the compression artifacts, and they are the price you pay for the small size of the output image file. Because of that, it is not a good idea to choose this format if you need to save screenshots of dialog windows, or screenshots with large amount of text within.

Summary

In today’s world of light-speed fast Internet, PNG has become the prevailing format on the Web. Indeed, it merges a high-quality, artifacts-free compression, the alpha-channel and a quite good compressed size. That’s why this format is the default selection for saving screenshots with WinSnap.
