Is there a handy way to rasterise the paths obtained via pen protocol in a cross-platform manner?

  • CocoaPen/QuartzPen is pretty handy unless you are on a non-macOS environment (e.g. Google Colab)
  • QtPen/WxPen is useful only if it's already used within your codebase as a widget toolkit
  • skia-pathops is a library dedicated to boolean operations but not for drawing

I might be missing something, but I couldn't find a solution that fully suits my needs. After all, I wrote a pen that finds the existing FreeType installation on the system, constructs FT_Outline and let FreeType rasterise the paths. As mentioned in #1769, I agree this is out of scope, but on the other hand I think it makes more sense to wrap it as a pen. If you are interested, I'll share and compile a PR.

I think it would be nice to have a pen that uses freetype-py to rasterize a glyph, yes please send a PR thanks!
