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.

Nostalgia .Net |
|
.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
