Member Data Documentation

◆ horizontalLeftOrigin

D2D1_POINT_2L DWRITE_GLYPH_IMAGE_DATA::horizontalLeftOrigin

Left origin along the horizontal Roman baseline.

◆ horizontalRightOrigin

D2D1_POINT_2L DWRITE_GLYPH_IMAGE_DATA::horizontalRightOrigin

Right origin along the horizontal Roman baseline.

◆ imageDataSize

UINT32 DWRITE_GLYPH_IMAGE_DATA::imageDataSize

Size of glyph data in bytes.

◆ pixelSize

D2D1_SIZE_U DWRITE_GLYPH_IMAGE_DATA::pixelSize

◆ pixelsPerEm

UINT32 DWRITE_GLYPH_IMAGE_DATA::pixelsPerEm

Pixels per em of the returned data. For non-scalable raster data (PNG/TIFF/JPG), this can be larger or smaller than requested from GetGlyphImageData when there isn't an exact match. For scaling intermediate sizes, use: desired pixels per em * font em size / actual pixels per em.

◆ uniqueDataId

UINT32 DWRITE_GLYPH_IMAGE_DATA::uniqueDataId

Unique identifier for the glyph data. Clients may use this to cache a parsed/decompressed version and tell whether a repeated call to the same font returns the same data.

◆ verticalBottomOrigin

Bottom origin along vertical central baseline.

◆ verticalTopOrigin

D2D1_POINT_2L DWRITE_GLYPH_IMAGE_DATA::verticalTopOrigin

Top origin along the vertical central baseline.
