Member Function Documentation

virtual TextVectorFace* osg::TextBackend::createVectorFace	(	const std::string &	family,
		TextFace::Style	style
	)			[virtual]

Creates a new vector face. Descendants of the TextBackend class have to override this method with their own implementation. The default implementation of the TextBackend class always return 0.

Parameters:

	family	The font family of the face (Arial, Courier etc.)
	style	The style of the face (bold, italic etc.)

Returns:

The vector face object or 0 in case of an error.

virtual TextPixmapFace* osg::TextBackend::createPixmapFace	(	const std::string &	family,
		TextFace::Style	style,
		UInt32	size
	)			[virtual]

Creates a new pixmap face. Descendants of the TextBackend class have to override this method with their own implementation. The default implementation of the TextBackend class always returns 0.

Parameters:

	family	The font family of the face (Arial, Courier etc.)
	style	The style of the face (bold, italic etc.)
	size	The size of the pixmap font in pixels.

Returns:

The pixmap face object or 0 in case of an error.

virtual TextTXFFace* osg::TextBackend::createTXFFace	(	const std::string &	family,
		TextFace::Style	style,
		const TextTXFParam &	param
	)			[virtual]

Creates a new TXF face. Descendants of the TextBackend class have to override this method with their own implementation. The default implementation of the TextBackend class always returns 0.

Parameters:

	family	The font family of the face (Arial, Courier etc.)
	style	The style of the face (bold, italic etc.)
	param	Some parameters that affect the creation of the TXF face.

Returns:

The TXF face object or 0 in case of an error.

virtual void osg::TextBackend::getFontFamilies

(

std::vector< std::string > &

families

)

[pure virtual]

Returns the names of all font families available.

Parameters:

families

A vector that gets filled with the names of all font families.

const TextBackend& osg::TextBackend::operator=

(

const TextBackend &

)

[private]

Copy operator (not implemented!)
