Paint.NET is image and photo manipulation software designed to be used on computers that run Windows. It supports layers, unlimited undo, special effects, and a wide variety of useful and powerful tools. It started development as an undergraduate college senior design project mentored by Microsoft, and is currently being maintained by some of the alumni that originally worked on it. Originally intended as a free replacement for the MS Paint software that comes with Windows, it has grown into a powerful yet simple tool for photo and image editing. The programming language used to create Paint.NET is C#, with a small amount of C++ for installation and shell-integration related functionality.
- Performance in many areas has been substantially improved, and overall memory usage has also been greatly reduced (especially when more than 1 image is open).
- The user interface has been refreshed with new icons, and visual styling has been enhanced for Aero Glass (Windows 7 / Vista only).
- Upgraded to use the latest .NET Framework 3.5 SP1, which has many built-in performance improvements.
- New effect: Blurs -> Surface Blur, by Ed Harvey
- New effect: Distort -> Dents, by Ed Harvey
- New effect: Distort -> Crystalize, by Ed Harvey
- The font manager for the Text Tool has been completely rewritten, resulting in increased performance and better reliability. On Windows 7, the quality of text is much better as a result of using DirectWrite (this also works on Windows Vista if you have installed DirectX 11).
- The built-in updater now has the ability to download updates in the background, and will wait until you exit Paint.NET to install them. In previous versions, the download happened in the foreground, and you had to wait for the entire process to complete before you could use Paint.NET again.
- Now includes a Russian translation.
For the Classic release, you should be offered the update automatically within the next week or so. You can get the updater soon by going to Settings → Updates → Check Now. You can also download and install it directly from the website.
- New: Completely redone high-res icons throughout the app which match the Microsoft Office style guidelines, with native support for up to 400% scaling (384 DPI)
- New: File -> Save All (thanks @Bruce Bowyer-Smyth!)
- New: Turkish language
- New: Move Layer commands are now present in the Layers menu, not just on the Layers window
- New: Layers -> Rotate 180 (thanks @null54!)
- New: Plugins can now use the UIScaleFactor class, which simplifies making decisions about DPI and scaling
- Improved: Image thumbnail list at the top of the main window now reacts to horizontal mouse wheel or trackpad swiping
- Improved: The Text Tool’s "Font Size Metric" button now has a tooltip explaining it
- Improved: When many images are open, Paint.NET now closes significantly faster (thanks @Bruce Bowyer-Smyth for the fix!)
- Improved: File -> Open Recent now has up to 10 images (up from 8 )
- Changed: Ctrl+Shift+F6 and +F7 will now also reset the floating window sizes for History and Layers, respectively (same if you Ctrl+Shift+Click on the button at the top-right of the main window)
- Changed: (for plugins) EffectFlags.SingleRenderCall is deprecated. Plugins should use the new EffectRenderingSchedule.None option instead.
- Changed: Settings -> Plugin Errors now shows up even if there are no plugin errors. This ensures consistency, especially with the newly asynchronous nature of plugin loading (otherwise there’s no way to distinguish "no errors" from "not done loading plugins").
- Fixed: Items in the File -> Open Recent menu will no longer get bigger or smaller when moving between monitors with different DPIs
- Fixed: An icon handle was being leaked every time a dialog was opened (thanks @null54 for the fix!)
- Fixed a crash when running GPU effects (e.g. Black & White) on very large, very tall images
- Fixed: "Bad" plugins can no longer ruin the undo system by rendering outside of the selection (thanks @BoltBait for helping out with this!)
