GetFontLanguageInfo
[Now
Supported on Windows NT]
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 |
|
); |
|
Parameters
hdc
Handle to a
display context.
Return Values
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.
