The old algorithm removed segments from edges to make the auto-hinter ignore a tilde. However, the implementation had two flaws. - Edge array elements were moved around without reordering them afterwards. - The linking between edges and segments wasn't correctly updated for moved edges, which could cause endless loops. Correcting both problems are non-trivial; additionally, a fix would make the auto-hinter slower. For these reasons, a new, simpler approach is taken: A new flag allows points to be tagged as being ignored, and if such a point is enountered, it doesn't get added to a segment. Fixes issue #1333. * src/autofit/afhints.h (AF_FLAG_IGNORE): New macro. * src/autofit/aflatin.c (af_latin_hints_compute_segments, af_touch_contour): Use it. (af_remove_segments_containing_point, af_remove_top_points_from_edges, af_remove_bottom_points_from_edges): Removed. (af_latin_stretch_top_tilde): Call `af_touch_top_contours` and `af_touch_bottom_contours` unconditionally. (af_latin_hints_apply): Updated. |
