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.
Changes:
This is a minor update that adds a new effect, improves certain parts of the user interface, and fixes a few minor bugs.
* New: Pencil Sketch effect
* New: In Windows Vista, the new-style Save/Open dialogs are used
* Changed: The View->Units, Image->Flip, Image->Rotate, and Layers->Flip submenus have been "flattened" (their commands were moved out into the View, Image, Image, and Layers menus respectively)
* Improved: Download size reduced by about 300 KB by using PNGOUT
* Improved: Some uses of confusing "MessageBox" style dialogs have been changed to a much friendlier "TaskDialog" style interface
* Improved: When changing the language, Paint.NET can now restart itself automatically
* Improved: Performance for Move Selected Pixels tool for quad-core systems
* Removed: The "Clear History" button has been removed because it was not very useful
* Fixed: Sometimes the Colors window would get "lost" between sessions of Paint.NET
* Fixed: Stack-overflow crash when using certain effects, such as Gaussian Blur, on very large images with certain settings (such as a 200 pixel radius)
* Fixed: When cancelling the multi-image Unsaved Changes dialog, the input focus was sometimes confused
* Changed: Renamed PdnLib.dll to PaintDotNet.Core.dll
* Fixed: Very rare race condition in background thumbnail renderer
