Member Function Documentation

bool GR_PangoFont::doesGlyphExist ( UT_UCS4Char g ) const [virtual]

Determine if character g exists in this font. We assume here that coverage is not affected by font size -- since we only operate with single fonts and assume scalable fonts, this should be OK.

NB: it is essential that this function is fast

Reimplemented from GR_Font.

bool GR_PangoFont::glyphBox	(	UT_UCS4Char	g,
		UT_Rect &	rec,
		GR_Graphics *	pG
