I've submitted a draft proposal and I appreciate any comments on it. I also submitted it as a final proposal just to be safe this close to the deadline but I can edit my final submission anytime.

I elaborated a bit in the proposal but I went with the root mean square measurement for contrast. Given the appearance of font glyphs, it made the most sense to take into account the average intensity of the glyph and the intensity of each pixel to obtain a nice overall measurement of contrast. In other image contrast calculations that only take into account the most intense and least intense pixel, we might find the contrast to be the same for two similar (but different on a pixel level) glyphs. _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
