IDWriteFactory3::CreateGlyphRunAnalysis method (dwrite_3.h)

  • Article

Creates a glyph-run-analysis object that encapsulates info that DirectWrite uses to render a glyph run.

Syntax

HRESULT CreateGlyphRunAnalysis(
  [in]           DWRITE_GLYPH_RUN const     *glyphRun,
  [in, optional] DWRITE_MATRIX const        *transform,
                 DWRITE_RENDERING_MODE1     renderingMode,
                 DWRITE_MEASURING_MODE      measuringMode,
                 DWRITE_GRID_FIT_MODE       gridFitMode,
                 DWRITE_TEXT_ANTIALIAS_MODE antialiasMode,
                 FLOAT                      baselineOriginX,
                 FLOAT                      baselineOriginY,
  [out]          IDWriteGlyphRunAnalysis    **glyphRunAnalysis
);

Parameters

[in] glyphRun

Type: DWRITE_GLYPH_RUN

A DWRITE_GLYPH_RUN structure that contains the properties of the glyph run.

[in, optional] transform

Type: DWRITE_MATRIX

A DWRITE_MATRIX structure that describes the optional transform to be applied to glyphs and their positions.

renderingMode

Type: DWRITE_RENDERING_MODE1

A DWRITE_RENDERING_MODE1-typed value that specifies the rendering mode, which must be one of the raster rendering modes (that is, not default and not outline).

measuringMode

Type: DWRITE_MEASURING_MODE

A DWRITE_MEASURING_MODE-typed value that specifies the measuring method for glyphs in the run. This method uses this value with the other properties to determine the rendering mode.

gridFitMode

Type: DWRITE_GRID_FIT_MODE

A DWRITE_GRID_FIT_MODE-typed value that specifies how to grid-fit glyph outlines. This value must be non-default.

antialiasMode

Type: DWRITE_TEXT_ANTIALIAS_MODE

A DWRITE_TEXT_ANTIALIAS_MODE-typed value that specifies the type of antialiasing to use for text when the rendering mode calls for antialiasing.

baselineOriginX

Type: FLOAT

The horizontal position of the baseline origin, in DIPs, relative to the upper-left corner of the DIB.

baselineOriginY

Type: FLOAT

The vertical position of the baseline origin, in DIPs, relative to the upper-left corner of the DIB.

[out] glyphRunAnalysis

Type: IDWriteGlyphRunAnalysis**

A pointer to a memory block that receives a pointer to a IDWriteGlyphRunAnalysis interface for the newly created glyph-run-analysis object.

Return value

Type: HRESULT

If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
