Yes. The original version involves complex remainder accounting. I strongly suspect that it breaks down a bit upon entering gray_render_scanline. That function should be aware of the remainder above, but it is not. You are welcome to track it down but it is a tough code to grasp. _______________________________________________ Freetype-devel mailing list Freetype-devel@nongnu.org https://lists.nongnu.org/mailman/listinfo/freetype-devel
