IPrintCoreHelperPS::GetFontSubstitution method (prcomoem.h)
The IPrintCoreHelperPS::GetFontSubstitution method indicates which device font, if any, is used as a substitution font for a specified TrueType font.
HRESULT GetFontSubstitution( [in] IN PCWSTR pszTrueTypeFontName, [out] OUT PCWSTR *ppszDevFontName );
A pointer to a null-terminated Unicode string that contains the name of a TrueType font.
A pointer to a variable that receives the address of a null-terminated Unicode string. This string contains the name of the device font that will be used in place of the TrueType font specified in the pszFontName parameter. If there is no device font that can serve as a substitute for the specified TrueType font, this parameter will be set to NULL.
IPrintCoreHelperPS::GetFontSubstitution should return one of the following values:
|S_OK||The method read the option for the specified feature.|
|E_FAIL||The font that was requested does not exist or was not a TrueType font.|
|E_INVALIDARG||One or more of the arguments is invalid.|
|E_OUTOFMEMORY||The core driver was not able to service the request because there was insufficient memory.|
|E_UNEXPECTED, or other return codes not listed here||The core driver seems to be in an invalid state. The caller should return a failure code.|
If an application attempts to print text that uses the TrueType font specified in the pszTrueTypeFontName parameter, that text will instead be printed in the device font specified in the ppszDevFontName parameter. The device font name must be that of a valid, installed font.
A font is identified by its font face name, which appears in the lfFaceName member of the LOGFONT structure.
To obtain a list of available fonts, create an information context for the current printer, and call SetGraphicsMode(hIC, GM_ADVANCED). Then enumerate device fonts by means of a call to EnumFontFamilies. The callback parameter (see EnumFontFamProc) of EnumFontFamilies should filter for device fonts by incrementing a counter for each font for which the bitwise AND result (FontType & TRUETYPE_FONTTYPE) is nonzero.
