The SetMapperFlags function alters the algorithm the font mapper uses when it maps logical fonts to physical fonts.
DWORD SetMapperFlags(
| HDC hdc, | // handle of device context |
| DWORD dwFlag | // font-mapper flag |
| ); |
Parameters
hdc
Identifies the device context that contains the font-mapper flag.
dwFlag
Specifies whether the font mapper should attempt to match a font's aspect ratio to the current device's aspect ratio. If bit zero is set, the mapper selects only matching fonts.
Return Values
If the function succeeds, the return value is the previous value of the font-mapper flag.
If the function fails, the return value is GDI_ERROR. To get extended error information, call GetLastError.
Remarks
If the dwFlag parameter is set and no matching fonts exist, Windows chooses a new aspect ratio and retrieves a font that matches this ratio.
The remaining bits of the dwFlag parameter must be zero.
