Function Documentation

LoadWin32Font() [1/2]

void LoadWin32Font

(

FontSize

fs

)

Loads the GDI font.

If a GDI font description is present, e.g. from the automatic font fallback search, use it. Otherwise, try to resolve it by font name.

Parameters

fs	The font size to load.

LoadWin32Font() [2/2]

void LoadWin32Font	(	FontSize	fs,
		const std::string &	file_name,
		uint	size
	)

Load a TrueType font from a file.

Parameters

fs	The font size to load.
file_name	Path to the font file.
size	Requested font size.

References FS_MONO, and MemSetT().

SetFallbackFont()

bool SetFallbackFont	(	struct FontCacheSettings *	settings,
		const std::string &	language_isocode,
		int	winlangid,
		class MissingGlyphSearcher *	callback
	)

We would like to have a fallback font as the current one doesn't contain all characters we need.

This function must set all fonts of settings.

Parameters

settings	the settings to overwrite the fontname of.
language_isocode	the language, e.g. en_GB.
winlangid	the language ID windows style.
callback	The function to call to check for missing glyphs.

Returns

true if a font has been set, false otherwise.
