public BufferDiffFlags diff (Buffer reference, Codepoint dottedcircle_glyph, uint position_fuzz)
If dottedcircle_glyph is (hb_codepoint_t) -1 then DOTTED_CIRCLE_PRESENT and NOTDEF_PRESENT are never returned.
This should be used by most callers if just comparing two buffers is needed.
| reference |
other buffer to compare to. |
| dottedcircle_glyph |
glyph id of U+25CC DOTTED CIRCLE, or (hb_codepoint_t) -1. |
| position_fuzz |
allowed absolute difference in position values. |
| buffer |
a buffer. |
