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.

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.

Return Value

Type: harfbuzz.types.BufferDiffFlags
