DWRITE_OPTICAL_ALIGNMENT enumeration
The optical margin alignment mode.
By default, glyphs are aligned to the margin by the default origin and side-bearings of the glyph. If you specify DWRITE_OPTICAL_ALIGNMENT_NO_SIDE_BEARINGS, then the alignment uses the side bearings to offset the glyph from the aligned edge to ensure the ink of the glyphs are aligned.
Syntax
typedef enum _DWRITE_OPTICAL_ALIGNMENT { DWRITE_OPTICAL_ALIGNMENT_NONE, DWRITE_OPTICAL_ALIGNMENT_NO_SIDE_BEARINGS } DWRITE_OPTICAL_ALIGNMENT;
Constants
- DWRITE_OPTICAL_ALIGNMENT_NONE
-
Align to the default origin and side-bearings of the glyph.
- DWRITE_OPTICAL_ALIGNMENT_NO_SIDE_BEARINGS
-
Align to the ink of the glyphs, such that the black box abuts the margins.
