What's Changed

This is a brand new version with 2-3x faster performance. It also resolves an issue with a specific SVG causing an error, and all users are advised to upgrade to this version.

    39.6 ops/s, ±1.72%   | fastest

    10.9 ops/s, ±31.43%   | 72.47% slower

  svg2img(canvg + node-canvas):
    10.8 ops/s, ±28.52%   | slowest, 72.73% slower

The upgrade will be hard due to the big changes made to upstream resvg. resvg 0.28.0 started with the removal of the ability to output SVG string, and we had to backport that functionality to a new crate: usvg-writer.

Eventually, we upgraded resvg for 2 successive versions, and are now at the latest 0.29.0.

  • chore: remove bench-related dependencies. #200 Thanks to @yisibl


  • fix: 'the previous segment must be M/L/C' error. #204 Thanks to @yisibl

    This is a normal error thrown by resvg when parsing Path Command, and has been confirmed as fixed in resvg 0.29.0.

    Add a test to ensure it is now fixed.
