Paint.NET is an open source, raster graphics editing program for Windows, developed on the .NET Framework. Paint.NET has evolved from a simple replacement for the Microsoft Paint program, which is included with Windows, into a powerful editor with support for layers, blending, transparency, and plugins.
Paint.NET has many of the powerful features that expensive commercial applications have, including the ability to use layers.
- Simple, intuitive, and innovative user interface. Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance.
- Layers. Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience.
- Frequently Updated. Updates usually come about every 4 to 6 weeks, and contain new features, performance improvements, and bug fixes.
- Special Effects. Many special effects are included for enhancing and perfecting your images. Everything from blurring, sharpening, red-eye removal, distortion, noise, and embossing are included. Also included is our unique 3D Rotate/Zoom effect that makes it very easy to add perspective and tilting.
- Adjustments are also included which help you tweak an image's brightness, contrast, hue, saturation, curves, and levels.
- Powerful Tools. Paint.NET includes simple tools for drawing shapes, including an easy-to-use curve tool for drawing splines or Bezier curves.
- Unlimited History. Once you've undone an action, you can also redo it. The length of the history is only limited by available disk space.
- Open Source and Free.
Paint.Net requires the .NET Framework 2 in order to run.
- Added: "Fluid mouse input" option in Settings -> UI -> Troubleshooting. If you see major glitches while drawing, try disabling this.
- Improved: Default brush size, font size, and corner radius size now scales with major DPI scaling levels (brush size of 2 at 100% scaling, brush size of 4 at 200% scaling, etc).
- Improved: Default image size now scales with major DPI scaling levels (800x600 at 100%, 1600x1200 at 200%, etc.).
- Improved performance and drawing latency by removing explicit calls to System.GC.Collect() except when low memory conditions are encountered.
- Improved performance by greatly reducing object allocation amplification by reducing the concurrency level when using ConcurrentDictionary, and by removing WeakReference allocations in favor of direct GCHandle usage.
- Improved: Performance and battery usage by ensuring animations always run at the monitor's actual refresh rate.
- Improved (reduced) CPU usage when moving the mouse around the canvas
Removed: "Hold Ctrl to hide handle" from the Text tool because it was not useful and caused lots of confusion.
- Fixed: Various high-DPI fixes, including horrible looking mouse cursors caused by a bug in .the latest .NET WinForms update.
- Fixed: Gradient tool no longer applies dithering "outside" of the gradient (in areas that should have a solid color).
- Fixed: Very slow performance opening the Effects menu when lots of plugins are installed after installing the Windows 10 Creators Update.
- Fixed: When cropping and then performing an undo, the scroll position was totally wrong.
- Fixed a rendering glitch in the Save Configuration dialog (it would "wiggle").
- Fixed: At certain brush sizes, the brush indicator on the canvas had a visual glitch in it due to a bug in Direct2D.
- Fixed: Text tool buttons for Bold, Italics, Underline were not localized for a few languages.
- Fixed a rare crash in the taskbar thumbnails.
- Fixed: Drawing with an aliased brush and opaque color (alpha=255) sometimes resulted in non-opaque pixels due to a bug in Direct2D's ID2D1RenderTarget::FillOpacityMask.
- Fixed: "Olden" effect should no longer cause crashes (it still has some rendering artifacts due to its multithreading problems, however).
