Although I'm unsure of the feasibility of it, my initial thought was to sum the pixel intensity differences between the baseline and test glyphs. Supposedly, these values could be stored for every glyph (although maybe not for 12 million) in an index, and we could consider these values when displaying the glyphs in the browser. This could help focus on the pairs with the greatest differences. However, as you've said in your second suggestion, a demo test will help determine what sort of comparison method will do. _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
