The EnumFontFamProc function is an application-defined callback function that retrieves data describing available fonts.
int CALLBACK EnumFontFamProc(
ENUMLOGFONT FAR *lpelf, |
// pointer to logical-font data |
NEWTEXTMETRIC FAR *lpntm, |
// pointer to physical-font data |
int FontType, |
// type of font |
LPARAM lParam |
// address of application-defined data |
); |
DEVICE_FONTTYPE
RASTER_FONTTYPE
TRUETYPE_FONTTYPE
The return value must be a nonzero value to continue enumeration; to stop enumeration, it must return zero.
An application must register this callback function by passing its address to the EnumFontFamilies function.
The EnumFontFamProc function is a placeholder for the application-defined function name.
The AND (&) operator can be used with the RASTER_FONTTYPE, DEVICE_FONTTYPE, and TRUETYPE_FONTTYPE constants to determine the font type. If the RASTER_FONTTYPE bit is set, the font is a raster font. If the TRUETYPE_FONTTYPE bit is set, the font is a TrueType font. If neither bit is set, the font is a vector font. DEVICE_FONTTYPE is set when a device (for example, a laser printer) supports downloading TrueType fonts or when the font is a device-resident font; it is zero if the device is a display adapter, dot-matrix printer, or other raster device. An application can also use DEVICE_FONTTYPE to distinguish graphics device interface (GDI)-supplied raster fonts from device-supplied fonts. GDI can simulate bold, italic, underline, and strikeout attributes for GDI-supplied raster fonts, but not for device-supplied fonts.
