Member Function Documentation

◆ FallbackShape()

void ICURun::FallbackShape ( UChar * buff )

Manually shape a run for built-in non-truetype fonts.

Similar to but not quite the same as UniscribeRun::FallbackShape.

Parameters

buff	The complete buffer of the run.

◆ Shape()

void ICURun::Shape	(	UChar *	buff,
		size_t	buff_length
	)

Shape a single run.

Parameters

buff	The buffer of which a partial (depending on start/length of the run) will be shaped.
length	The length of the buffer.
