DWRITE_GLYPH_RUN structure
Contains the information needed by renderers to draw glyph runs. All coordinates are in device independent pixels (DIPs).
Syntax
struct DWRITE_GLYPH_RUN { IDWriteFontFace *fontFace; FLOAT fontEmSize; UINT32 glyphCount; const UINT16 *glyphIndices; const FLOAT *glyphAdvances; const DWRITE_GLYPH_OFFSET *glyphOffsets; BOOL isSideways; UINT32 bidiLevel; };
Members
- fontFace
-
Type: IDWriteFontFace*
-
The physical font face object to draw with.
- fontEmSize
-
Type: FLOAT
-
The logical size of the font in DIPs (equals 1/96 inch), not points.
- glyphCount
-
Type: UINT32
-
The number of glyphs in the glyph run.
- glyphIndices
-
Type: const UINT16*
-
A pointer to an array of indices to render for the glyph run.
- glyphAdvances
-
Type: const FLOAT*
-
A pointer to an array containing glyph advance widths for the glyph run.
- glyphOffsets
-
Type: const DWRITE_GLYPH_OFFSET*
-
A pointer to an array containing glyph offsets for the glyph run.
- isSideways
-
Type: BOOL
-
If true, specifies that glyphs are rotated 90 degrees to the left and vertical metrics are used. Vertical writing is achieved by specifying isSideways = true and rotating the entire run 90 degrees to the right via a rotate transform.
- bidiLevel
-
Type: UINT32
-
The implicit resolved bidi level of the run. Odd levels indicate right-to-left languages like Hebrew and Arabic, while even levels indicate left-to-right languages like English and Japanese (when written horizontally). For right-to-left languages, the text origin is on the right, and text should be drawn to the left.
