so if I understand correctly, this is a monochrome-only (not anti-aliased) rasterizer that probably doesn't handle the subtle drop-out control rules we need for fonts.

I'm still interested to see how this works though. Anyone has the source code ?, I feel reluctant to download and unpack a 80 MB tarball just to see this.

The performance of rasterizing various paths with QRasterizer compared to the Freetype rasterizer can bee seen in the following figure:





Very interesting!
