Svg.Skia

Skia SVG rendering library.

About

The Svg.Skia is using internally SVG library from NuGet to load Svg object model. The original Svg library provides only System.Drawing rendering backend. The Svg.Skia library is providing rendering backend implementation using SkiaSharp that aims to be at least on par or more complete then original System.Drawing implementation and also more performant. The Svg.Skia can be also 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.
