Paint.net
  (Redirected from Paint.NET v3.5.10)
Paint.net (stylized as Paint.NET or paint.net) is a freeware raster graphics editor program for Microsoft Windows, developed on the .NET Framework. Paint.net was originally created by Rick Brewster as a Washington State University student project,[3] and has evolved from a simple replacement for the Microsoft Paint program into a program for editing mainly graphics, with support for plugins.

History
Paint.net originated as a computer science senior design project during spring 2004 at Washington State University. Version 1.0 consisted of 36,000 lines of code and was written in fifteen weeks.[4] In contrast, version 3.35 has approximately 162,000 lines of code. The paint.net project continued over the summer and into the autumn 2004 semester for both the version 1.1 and 2.0 releases.
Development continues with one programmer who worked on previous versions of Paint.net while he was a student at WSU. As of May 2006 the program had been downloaded at least 2 million times,[5] at a rate of about 180,000 per month.[6]
Initially, Paint.net was released under a modified version of the MIT License, with the exclusion of the installer, text, and graphics.[7] It was completely open-source, but because breaches of license, all resource files (such as interface text and icons) were released under a non-free Creative Commons license forbidding modification, and the installer was made closed-source.[8] Version 3.36 was initially released as partial open-source, but Brewster later took down the source code, citing problems with plagiarism. In version 3.5, paint.net became proprietary software. Users are now prohibited from modifying it.[8][9]
Starting with version 4.0.18, paint.net is published in two editions: A classic edition remains freeware, similar to all other versions since 3.5. Another edition, however, is published to Microsoft Store under a trialware license and is available to purchase for US$7. According to the developer, this was done to enable the users to contribute to the development with more convenience, even though the old avenue of donation was not closed.[10][11]
Overview
Paint.net is primarily programmed in the C# programming language. Its native image format, .PDN, is a compressed representation of the application's internal object format, which preserves layering and other information.[12]
Plugins
Paint.net supports plugins, which add image adjustments, effects, and support for additional file types. They can be programmed using any .NET Framework programming language, though they are most commonly written in C#.[13] These are created by volunteer coders on the program's discussion board, the paint.net Forum. Though most are simply published via the discussion board, some have been included with a later release of the program. For instance, a DirectDraw Surface file type plugin, (originally by Dean Ashton) and an Ink Sketch and Soften Portrait effect (originally by David Issel) were added to Paint.net in version 3.10.
Hundreds of plugins have been produced;[14] such as Shape3D, which renders a 2D drawing into a 3D shape. Some plugins expand on the functionality that comes with Paint.net, such as Curves+ and Sharpen+, which extend the included tools Curves and Sharpen, respectively.
Examples of file type plugins include an Animated Cursor and Icon plugin and an Adobe Photoshop file format plugin.[14] Several of these plugins are based on existing open source software, such as a raw image format plugin that uses dcraw and a PNG optimization plugin that uses OptiPNG.
Forks
paint-mono
Paint.net was created for Windows, and has no native support for any other system. With its previous open-source nature, the possibility for alternate versions was available. In May 2007, Miguel de Icaza officially started a porting project called paint-mono.[15] This project had partially ported Paint.net 3.0 to Mono, an open-source implementation of the Common Language Infrastructure on which the .NET Framework is based. This allowed Paint.net to be run on Mono-supported platforms, such as Linux. This port is no longer maintained and has not been updated since March 2009.[15]
Pinta
Main article: Pinta (software)
In 2010 developer Jonathan Pobst started a project called Pinta, describing it as a clone of Paint.net for Mono and Gtk#. Pinta reused the adjustments and effects code from Paint.net but otherwise is original code.[16]

3.22January 12, 2008Adds a new Reduce Noise effect.
3.30April 10, 2008This release adds an Italian translation, a new "Fragment Blur" effect, and the ability to save PNG images at 8- and 24-bit color depths. For developers, the IndirectUI system has some new controls, some new constraint rules, and can now be used for file type plugins.
3.35June 7, 2008A new Posterize adjustment, a new Intersect selection mode, dramatically improved performance for selection editing.
3.5November 6, 2009Improved performance reliability, reducing memory usage, upgrading to the latest .NET Framework version, and refreshing the user interface for Aero and glass (Windows 7 / Vista)
3.5.2January 4, 2010Resolves some feature disparities in the Text tool between GDI (Windows XP) and DirectWrite (Windows 7/Windows Vista). It also improves overall performance, as well as the correctness and quality of the Move Selected Pixels tool, the Image->Resize function, and the Hue/Saturation adjustment.
