UFF_FONTDIRECTORY structure (prntfont.h)

  • Artikel

The UFF_FONTDIRECTORY structure is used to specify the directory of font descriptions contained in a Unidrv font format file (.uff file).

Syntax

typedef struct _UFF_FONTDIRECTORY {
  DWORD dwSignature;
  WORD  wSize;
  WORD  wFontID;
  SHORT sGlyphID;
  WORD  wFlags;
  DWORD dwInstallerSig;
  DWORD offFontName;
  DWORD offCartridgeName;
  DWORD offFontData;
  DWORD offGlyphData;
  DWORD offVarData;
} UFF_FONTDIRECTORY, *PUFF_FONTDIRECTORY;

Members

dwSignature

Specifies the font metrics record signature. This value must be FONT_REC_SIG.

wSize

Specifies the size, in bytes, of the UFF_FONTDIRECTORY structure.

wFontID

Specifies the font identifier. This value must match the wDataID member of a DATA_HEADER structure that specifies font metrics information within the .uff file.

sGlyphID

Specifies the glyph set identifier. This value specifies the glyph set that is to be associated with the font. See the following Remarks section.

wFlags

Is 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.

dwInstallerSig

Specifies the signature value of the font installer that installed the font.

offFontName

Specifies 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.

offCartridgeName

Specifies 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.

offFontData

Specifies the offset, in bytes, from the beginning of the .uff file to a DWORD-aligned DATA_HEADER structure specifying a font metrics section.

offGlyphData

Specifies 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.

offVarData

Specifies 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.

Remarks

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.
