I see warping is a kind of hinting where shifting/scaling is tweaked for all segments at once rather than for each segment individually. Therefore, warping option would replace normal hinting, of course. > >> - Autohinter LIGHT and LCD modes will switch to fractional advances > > For LIGHT, I'm not sure that we can do that for backward > compatibility... Yes, but such incompatibility should go either unnoticed or result in improvement as if we are fixing a bug: - If someone was using lsb_delta and rsb_delta correctly, then the fractional part just shifts from rsb_delta to fractional advance width, while lsb_delta is always 0 in LIGHT. There should not be no changes in layout whatsoever. - Even if someone was not using the deltas, he now has a chance to do his own rounding, whichever way. Nikolas is right, we have fractional advance with disabled hinting, so this is not a big surprise. _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
