The GetFontLanguageInfo function returns information about the currently selected font for the specified display context. Applications typically use this information and the GetCharacterPlacement function to prepare a character string for display.
DWORD GetFontLanguageInfo(
|
HDC hdc |
// handle to a device context |
|
); |
The return value identifies characteristics of the currently selected font. The function returns 0 if the font is “normalized” and can be treated as a simple Latin font; it returns GCP_ERROR if an error occurs. Otherwise, the function returns a combination of the following values:
|
Value |
Meaning |
|
GCP_DBCS |
The character set is DBCS. |
|
GCP_DIACRITIC |
The font/language contains diacritic glyphs |
|
FLI_GLYPHS |
The font contains extra glyphs not normally accessible using the codepage. Use GetCharacterPlacement to access the glyphs. This value is for information only and is not intended to be passed to GetCharacterPlacement. |
|
GCP_GLYPHSHAPE |
The font/language contains multiple glyphs per code point or per code point combination (supports shaping and/or ligation), and the font contains advanced glyph tables to provide extra glyphs for the extra shapes. If this value is given, the lpGlyphs array must be used with the GetCharacterPlacement function and the ETO_GLYPHINDEX value must be passed to the ExtTextOut function when the string is drawn. |
|
GCP_KASHIDA |
The font/ language permits Kashidas. |
|
GCP_LIGATE |
The font/language contains ligation glyphs which can be substituted for specific character combinations. |
|
GCP_USEKERNING |
The font contains a kerning table which can be used to provide better spacing between the characters and glyphs. |
|
GCP_REORDER |
The language requires reordering for display--for example, Hebrew or Arabic. |
The return value, when masked with FLI_MASK, can be passed directly to the GetCharacterPlacement function. To get extended error information, call GetLastError.
