DWRITE_OPTICAL_ALIGNMENT enumeration (dwrite_2.h)

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
} ;

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.
