Readme

The KGy SOFT Drawing Core Libraries package offers advanced drawing features for completely managed bitmap data on multiple platforms.

Among others:

Creating managed bitmap data of any pixel format on every platform.
Creating bitmap data for any preallocated buffer using any pixel format. This allows accessing the pixels of bitmaps of any technology if the bitmap data is exposed as a pointer or array.
Shape drawing with feature-rich brushes, pens and other drawing options.
Supporting color correct alpha blending.
Quantizing using predefined or optimized colors
Dithering using ordered, error diffusion, random noise or interleaved gradient noise dithering techniques.
Creating GIF animations even in high color.

See the online help for the complete documentation or the GitHub page for some highlighted code examples.

💡 Tip:

Feel free to explore the application examples to see how to use KGy SOFT Drawing Libraries in various environments such as MAUI, UWP, WinForms, WinUI, WPF and Xamarin.

For GDI+ specific solutions see the KGySoft.Drawing package. It makes possible to create managed, fast accessible bitmap data for the Bitmap class, supporting all pixel formats. It also contains many extensions for the Icon, Bitmap, Image, Metafile and Graphics types.

For WPF specific solutions see the KGySoft.Drawing.Wpf package. It makes possible to obtain managed, fast accessible bitmap data for a WriteableBitmap instance of any pixel format, offering all features of an IReadWriteBitmapData for a WriteableBitmap. It also offers extension methods for the BitmapSource class.

For dedicated UWP support see the KGySoft.Drawing.Uwp package.

For dedicated WinUI support see the KGySoft.Drawing.WinUI package.

For SkiaSharp specific solutions see the KGySoft.Drawing.SkiaSharp package. It makes possible to obtain managed, fast accessible bitmap data for SKBitmap and SKPixmap instances of any pixel format, offering all IReadWriteBitmapData features for them. It also offers extension methods for the SKImage, SKSurface, SKBitmap, SKPixmap and SKImageInfo classes.

See also the KGySoft.Drawing.Tools repository, which contains debugger visualizers for several bitmap, palette and color types of the frameworks listed above.
