Paint.NET is an image and photo manipulation application. Every feature and user interface element was designed to be immediately intuitive and quickly learnable without assistance. In order to handle multiple images easily, Paint.NET uses a tabbed document interface. The tabs display a live thumbnail of the image instead of a text description. This makes navigation very simple and fast.
Usually only found on expensive or complicated professional software, layers form the basis for a rich image composition experience. You may think of them as a stack of transparency slides that, when viewed together at the same time, form one image.
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. You can also convert an image to black and white, or sepia-toned.
Paint.net 4.2.16 changelog:
- New: Effect -> Color -> Quantize, which applies palette reduction to 256 colors or less, along with dithering. This is the same algorithm used when saving images at 8-bit color depth or lower.
- Fixed and improved palette generation when saving at 8-bit color depth or less
- Greatly optimized performance of palette generation and image quantization
- Added option to choose between Octree (default) and Median Cut algorithms for palette quantization when saving at 8-bit color depth or less
- Fixed a crash in Move tools when the selection was 0-width and/or 0-height
- Added tooltips w/ shortcut keys to the Tools dropdown in the toolbar
- Fixed IndirectUI ColorWheel rendering (thanks @toe_head2001!)
- Fixed a crash in the Text tool when using Ctrl+(Left,Right,Backspace,Delete) (thanks @Bruce Bowyer-Smyth!)
- Changed: New layers are now filled with #00000000 instead of #00FFFFFF
- Fixed a crash when working with selections (OutOfMemoryException)
- New: Effects can now access the Document’s DPI via EffectEnvironmentParameters.DocumentResolution
- Fixed drawing of the color palette in the Colors window when using some non-standard DPI scaling settings (e.g. 1.15x)
- Fixed a crash when using @Ed Harvey‘s Threshold plugin
- Fixed the return value from PdnRegion.GetBoundsInt() so it’s not anchored at (0,0) unless it should be
- Fixed premultiplied-to-straight color conversion on some code paths (thanks @null54!)
- Updated bundled AvifFileType plugin to v22.214.171.124, which includes performance optimizations and bug fixes. See its GitHub releases page (https://github.com/0xC0000054/pdn-avif/releases) for more info. (thanks @null54!)
- Updated bundled DDSFileTypePlus plugin to v126.96.36.199, which uses an updated version of DirectXTex (2021-04-06). (thanks @null54!)
