Svg.Skia

Svg.Skia is an SVG rendering library.

About

Svg.Skia can be used as a .NET library or as a CLI application to render SVG files based on a static SVG Full 1.1 subset to raster images or to a backend's canvas.

The Svg.Skia is using SVG library to load Svg object model.

The Svg.Skia library is implemented using SkiaSharp rendering backend that aims to be on par or more complete then original System.Drawing implementation and more performant and cross-platform.

The Svg.Skia can be used in same way as the SkiaSharp.Extended.Svg (load svg files as SKPicture).

The Svg library has more complete implementation of Svg document model then SkiaSharp.Extended.Svg and the Svg.Skia renderer will provide more complete rendering subsystem implementation.
