Here is an example two stems shifted but with the same spacing [0 64] [260 324] [30 94] [290 354] after hinting [0 64] [256 320] [0 64] [320 384] This is ugly! Forget hinting in the context of subpixel positioning. Nothing better than lsb_ and rsb_delta exists, _______________________________________________ Freetype-devel mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/freetype-devel
