IDWriteGlyphRunAnalysis::GetAlphaTextureBounds method (dwrite.h)
Gets the bounding rectangle of the physical pixels affected by the glyph run.
HRESULT GetAlphaTextureBounds( DWRITE_TEXTURE_TYPE textureType, [out] RECT *textureBounds );
Specifies the type of texture requested. If a bi-level texture is requested, the bounding rectangle includes only bi-level glyphs. Otherwise, the bounding rectangle includes only antialiased glyphs.
When this method returns, contains the bounding rectangle of the physical pixels affected by the glyph run, or an empty rectangle if there are no glyphs of the specified texture type.
If this method succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
