OSGTEXT_EXPORT std::string osgText::findFontFile

(

const std::string &

str

)

OSGTEXT_EXPORT Font* osgText::readFontFile	(	const std::string &	filename,
		const osgDB::ReaderWriter::Options *	userOptions = 0
	)

Read a font from specified file. The filename may contain a path. It will search for the font file in the following places in this order:

• In the current directory
• All paths defined in OSG_FILE_PATH or OSGFILEPATH environment variable
• Filename with path stripped: In the current directory
• Filename with path stripped: All paths defined in OSG_FILE_PATH or OSGFILEPATH

Then the file will be searched in OS specific directories in the following order:

• Again in the current directory
• Windows: In C:/winnt/fonts
• Windows: In C:/windows/fonts
• Windows: In the fonts directory of the windows install directory
• Other OS: In /usr/share/fonts/ttf
• Other OS: In /usr/share/fonts/ttf/western
• Other OS: In /usr/share/fonts/ttf/decoratives

If the given file could not be found, the path part will be stripped and the file will be searched again in the OS specific directories.

OSGTEXT_EXPORT Font* osgText::readFontStream	(	std::istream &	stream,
		const osgDB::ReaderWriter::Options *	userOptions = 0
	)
