Paint.NET是一个图像和照片处理软件，它由华盛顿州立大学的学生开发和维护并由微软公司提供项目指导，早期定位于MS Paint的免费替代软件，现在逐渐发展为一个功能强大且易用的的图像和照片处理软件，支持图层，无限制的历史记录，特效，和许多实用工具，并且开放源代 码和完全免费，界面看起来有点像Photoshop。该软件的开发语言是C#。Changelog:
- Note: New features will be displayed in English through the Alpha and Beta release(s). The final release will include full translations for the other supported languages.
- Fixed: If a floating tool window (Colors, History, Layers, Tools) was not docked/snapped, and the screen resolution was lowered or a Remote Desktop session was initiated, then the window would stay off screen and be "lost". It is now moved to keep it on-screen.
- Fixed: An issue for plugin developers where Effect`1.Render(3) was incorrectly throwing an exception when indirectly called through Effect.Render(6). This was preventing an updated version of the "Film Noir" plugin from working, even though its code was correct.
- Integrated updated translations for Spanish, French, Japanese, Korean, Portuguese (Brazil), and Chinese (Simplified). An updated German translation will be present in the final release.
