bufferDiff

If dottedcircle_glyph is (hb_codepoint_t) -1 then #HB_BUFFER_DIFF_FLAG_DOTTED_CIRCLE_PRESENT and #HB_BUFFER_DIFF_FLAG_NOTDEF_PRESENT are never returned. This should be used by most callers if just comparing two buffers is needed.

harfbuzz.buffer.Buffer reference

harfbuzz.types.Codepoint dottedcircleGlyph

uint positionFuzz

)

Parameters

buffer harfbuzz.buffer.Buffer: a buffer.
reference harfbuzz.buffer.Buffer: other buffer to compare to.
dottedcircleGlyph harfbuzz.types.Codepoint: glyph id of U+25CC DOTTED CIRCLE, or (hb_codepoint_t) -1.
positionFuzz uint: allowed absolute difference in position values.
