Note

Some information relates to pre-released product, which may be substantially modified before it's commercially released. Microsoft makes no warranties, express or implied, with respect to the information provided here.

Defines constants that specify which formats are supported in a font, either at a font-wide level or per glyph.

For color fonts, these formats can be used to represent color glyphs. Fonts can contain multiple drawable data formats for glyphs. And an app can use these values to tell DirectWrite which formats to return when splitting a color glyph run.

Specifies that the glyph has multilayered COLR data.
DWRITE_GLYPH_IMAGE_FORMATS_SVG
Value: 0x00000008
Specifies that the glyph has SVG outlines as standard XML. Fonts may store the content gzip'd rather than plain text, indicated by the first two bytes as gzip header {0x1F 0x8B}.
DWRITE_GLYPH_IMAGE_FORMATS_PNG
Value: 0x00000010
Specifies that the glyph has PNG image data, with standard PNG IHDR.
DWRITE_GLYPH_IMAGE_FORMATS_JPEG
Value: 0x00000020
Specifies that the glyph has JPEG image data, with standard JIFF SOI header.
DWRITE_GLYPH_IMAGE_FORMATS_TIFF
Value: 0x00000040
Specifies that the glyph has TIFF image data.
DWRITE_GLYPH_IMAGE_FORMATS_PREMULTIPLIED_B8G8R8A8

Specifies that the glyph has raw 32-bit premultiplied BGRA data.
DWRITE_GLYPH_IMAGE_FORMATS_COLR_PAINT_TREE
Value: 0x00000100

IMPORTANT

The DWRITE_GLYPH_IMAGE_FORMATS_COLR_PAINT_TREE constant is available in pre-release versions of the Windows Insider Preview.

Specifies that the glyph is represented by a tree of paint elements in the font's COLR table.
