IDWriteFontFace::GetGdiCompatibleMetrics method
Obtains design units and common metrics for the font face. These metrics are applicable to all the glyphs within a fontface and are used by applications for layout calculations.
Syntax
virtual HRESULT GetGdiCompatibleMetrics( FLOAT emSize, FLOAT pixelsPerDip, [in, optional] const DWRITE_MATRIX *transform, [out] DWRITE_FONT_METRICS *fontFaceMetrics ) = 0;
Parameters
- emSize
-
Type: FLOAT
The logical size of the font in DIP units.
- pixelsPerDip
-
Type: FLOAT
The number of physical pixels per DIP.
- transform [in, optional]
-
Type: const DWRITE_MATRIX*
An optional transform applied to the glyphs and their positions. This transform is applied after the scaling specified by the font size and pixelsPerDip.
- fontFaceMetrics [out]
-
Type: DWRITE_FONT_METRICS*
A pointer to a DWRITE_FONT_METRICS structure to fill in. The metrics returned by this function are in font design units.
