Paint.NET v3.5.4 is now available

This is another small update that fixes a few bugs. It also optimizes the Image->Flatten command for multiple CPUs/cores.

You can either use the built-in updater from the Utilities menu, or go to the website and download it. There’s no need to uninstall the old version; that will be taken care of automatically.

Changes and fixes since v3.5.3:

  • Improved performance of the Image->Flatten command by making it multithreaded.
  • Fixed the File->Save As dialog not opening to the correct folder.
  • Fixed a crash with certain plugins and their use of the File Open dialog.
  • Fixed a very rare crash with the toolbar’s font list.

By the way, this comic is completely true.

    I’m interested in PNG chunks, in particular iTXt, and was surprised and delighted to open a PNG image (not knowing it had been created by Paint.NET) in a disk editor and see several chunks. Among them is the iTXt chunk, and there was something like “created by Paint.NET.” Cool.

    Are you writing these chunks via the .NET API? I want to insert text in some archival PNG images, and haven’t found a utility to do so. A promising image metadata editor from Microsoft (unofficial) doesn’t handle PNG.

    I’m hoping to avoid writing my own.

    I (re)found TweakPNG, which supports the iTXt chunk since version 1.3 (current is 1.3.2).

    This utility shows that Paint.NET overwrites any iTXt chunk.
