View the official Windows Driver Kit DDI referenceNo description available.
The UFF_FONTDIRECTORY structure is used to specify the directory of font descriptions contained in a Unidrv font format file (.uff file).
dwSignatureSpecifies the font metrics record signature. This value must be FONT_REC_SIG.
wSizeSpecifies the size, in bytes, of the UFF_FONTDIRECTORY structure.
wFontIDSpecifies the font identifier. This value must match the wDataID member of a DATA_HEADER structure that specifies font metrics information within the .uff file.
sGlyphIDSpecifies the glyph set identifier. This value specifies the glyph set that is to be associated with the font. See the following Remarks section.
wFlagsIs a set of bit flags. One or more of the following flags can be specified.
| Flag | Definition |
|---|---|
| FONT_FL_DEVICEFONT | The font is a device font. |
| FONT_FL_GLYPHSET_GTT | The glyph set is specified in GTT format. |
| FONT_FL_GLYPHSET_RLE | The glyph set is specified in RLE format. |
| FONT_FL_IFI | Font metrics are specified in IFI format. |
| FONT_FL_PERMANENT_SF | The font is a PCL permanent soft font. |
| FONT_FL_SOFTFONT | The font is a PCL soft font. |
| FONT_FL_UFM | Font metrics are specified in UFM format. |
dwInstallerSigSpecifies the signature value of the font installer that installed the font.
offFontNameSpecifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned, NULL-terminated, Unicode string representing the name of the font.
offCartridgeNameSpecifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned, NULL-terminated, Unicode string representing the name of the font cartridge containing the font. If the font is not contained in a cartridge, this value should be zero.
offFontDataSpecifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned DATA_HEADER structure specifying a font metrics section.
offGlyphDataSpecifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned DATA_HEADER structure specifying a glyph set section. If sGlyphID is zero or negative, offGlyphData should be zero.
offVarDataSpecifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned DATA_HEADER structure specifying a data section. If the FONT_FL_PERMANENT_SF flag is set in wFlags, offVarData must be zero.
If sGlyphID is a greater than zero, it must match the wDataID member of a DATA_HEADER structure that specifies a glyph set within the .uff file.
If sGlyphID is less than zero, it must be one of the CC_-prefixed constants defined in prntfont.h, which identify predefined glyph sets.
If sGlyphID is zero, Unidrv uses the glyph set resource identifier contained in the font's UNIFM_HDR structure. The glyph set resource must be contained in the minidriver's resource DLL, or else Unidrv uses the default glyph translation.
