paint.net 4.1.7 alpha build 7079 is now available

I believe I’ve fixed the issues that were preventing some images from being saved (as reported earlier). I also fixed a few things in the Save Configuration dialog that were supposed to make it into alpha build 7077, but didn’t because I incorrectly merged my pull request on GitHub.

The issue with the images that wouldn’t save was that they had UserComment metadata in them (EXIF tag ID #37510). WIC (Windows Imaging Component) handles this in a way that my code wasn’t coping with, so the data didn’t round-trip correctly, and WIC decided to refuse the transaction instead. (And there was another bug: part of my wrapper was returning an error when WIC tried to send an IStream::Write() call with a 0 byte payload … weird, probably a bug in their code, but shouldn’t have broken down on my side.)

To download, head on over to the forum. I’m currently adding this to the auto-updater as well, so in a few minutes you should be able to open up the app and head over to Settings (gear icon at top right of main window) –> Updates, and click on the “Check Now” button (but make sure “Also check for pre-release (beta) versions of paint.net” is enabled!). For Microsoft Store users, you’ll need to install the Classic version to try this build out (I don’t yet have alpha/beta builds working for the Store). It can be installed side-by-side with the Store version and uninstalled when you’re done with it without affecting the Store copy.

Change log:

  • Fixed: Some images could not be saved as JPEG due to mishandling of some metadata
  • Fixed some error handling in the Save Configuration dialog. An error dialog will now pop up to show the exception that occurred in addition to the usual "Preview: (error)" text that has always been shown.
  • Fixed: HEIC/HEIF file extensions are now registered with Windows so that you can double-click on them in Explorer to open them in Paint.NET

Enjoy! :)

    I love Paint.net.

    I was just wondering if there were any plans to add support for JPEG 2000, JPEG XR, and / or WebP.

    From what I understand, these formats offer better compression than traditional JPEG.

    Thanks again for an awesome product!
