Yesterday I have discovered resvg, an MPL 2.0-licensed SVG rendering and optimisation library and a tool, written in Rust. It is said to be faster than some SVG renderers while currently slower than librsvg:
It aims to support the static subset of SVG better than other libraries:
The author writes:
One of the major differences from other rendering libraries is that resvg does a lot of preprocessing before rendering. It converts shapes to paths, resolves attributes, removes groups and invisible elements, fixes a lot of issues in malformed SVG files. Then it creates a simple render tree with all elements and attributes resolved. And only then it starts to render. So it's very easy to implement a new rendering backend.
- librsvg, currently, is heavily tied to the cairo library, unlike resvg
- librsvg is heavily tied to GNOME which makes it painful to distribute outside the Linux ecosystem
- librsvg doesn't really preprocess input files, rendering them as is
- librsvg has a minimal support of the edge-cases, which leads to rendering errors
I’m thinking of packaging this for Debian, but I would be interested to know what others think of this.
