IDWriteFontFace::GetDesignGlyphMetrics method (dwrite.h)

Obtains ideal (resolution-independent) glyph metrics in font design units.

Syntax

HRESULT GetDesignGlyphMetrics(
  [in]  UINT16 const         *glyphIndices,
        UINT32               glyphCount,
  [out] DWRITE_GLYPH_METRICS *glyphMetrics,
        BOOL                 isSideways
);

Parameters

[in] glyphIndices

Type: const UINT16*

An array of glyph indices for which to compute metrics. The array must contain at least as many elements as specified by glyphCount.

glyphCount

Type: UINT32

The number of elements in the glyphIndices array.

[out] glyphMetrics

Type: DWRITE_GLYPH_METRICS*

When this method returns, contains an array of DWRITE_GLYPH_METRICS structures. glyphMetrics must be initialized with an empty buffer that contains at least as many elements as glyphCount. The metrics returned by this function are in font design units.

isSideways

Type: BOOL

Indicates whether the font is being used in a sideways run. This can affect the glyph metrics if the font has oblique simulation because sideways oblique simulation differs from non-sideways oblique simulation

Return value

Type: HRESULT

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

Remarks

Design glyph metrics are used for glyph positioning.
