Paint.NET 4.0.17 / 3.5.11

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.

Features of Paint.NET:

- 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.

Attention:

Paint.Net requires the .NET Framework 2 in order to run.

Changes in recent version change history

- 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).
