Svg.Skia is an SVG rendering library.
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.
Svg.Skia is delivered as a NuGet package.
You can find the packages here NuGet and install the package like this:
Install-Package Svg.Skia
or by using nightly build feed:
