UNIFONTOBJ structure (printoem.h)

  • Article

The UNIFONTOBJ structure is used as an input parameter to font functions in rendering plug-ins.

Syntax

typedef struct _UNIFONTOBJ {
  ULONG      ulFontID;
  DWORD      dwFlags;
  IFIMETRICS *pIFIMetrics;
  PFNGETINFO pfnGetInfo;
} UNIFONTOBJ, *PUNIFONTOBJ;

Members

ulFontID

Specifies a resource identifier for an RC_UFM resource contained in a Unidrv minidriver's resource DLL. Supplied by Unidrv.

dwFlags

A set of Unidrv-supplied bit flags. Flag definitions are as follows:

Flag Definition
UFOFLAG_TTDOWNLOAD_BITMAP If set, the font is a bitmap font.
UFOFLAG_TTDOWNLOAD_TTOUTLINE If set, the font is a TrueType outline font.
UFOFLAG_TTFONT If set, the font is a downloadable TrueType font. If not set, the font is a device font.
UFOFLAG_TTOUTLINE_BOLD_SIM If set, the TrueType font has bold simulation done by GDI.
UFOFLAG_TTOUTLINE_ITALIC_SIM If set, the TrueType font has italic simulation done by GDI.
UFOFLAG_TTOUTLINE_VERTICAL If set, the TrueType font is a vertical font. Note that this flag is available only for those Asian fonts that can be written vertically. If not set, text is written horizontally.
UFOFLAG_TTSUBSTITUTED If set, the device font is a font substituted for the TrueType font. In the font substitution, GDI requests that Unidrv print using a TrueType font. For performance reasons, Unidrv substitutes a device font for the TrueType font. (The substitution is specified by a [generic printer description (GPD)](/windows-hardware/drivers/) file or in a table in the registry.) For this substitution, for some printers, it is necessary to adjust the baseline position of the device font, because the baseline position of the device font can be higher than that of the TrueType font. The adjustment causes the output of the substituted device font to be shifted down to correct this discrepancy. Depending on the flags set in the UNIFONTOBJ structure, the printer minidriver is able to adjust the baseline position of device fonts.

pIFIMetrics

Pointer to an IFIMETRICS structure. Supplied by Unidrv.

pfnGetInfo

Pointer to Unidrv's UNIFONTOBJ_GetInfo callback function. Supplied by Unidrv.
