Detailed Description

Subclass of vtkFreeTypeTools that uses system installed fonts.

vtkFontConfigFreeTypeTools defers to vtkFreeTypeTools for rendering and rasterization, but sources fonts from a FontConfig system lookup. If the lookup fails, the compiled fonts of vtkFreeType are used instead.

Warning: Do not instantiate this class directly. Rather, call vtkFreeTypeTools::GetInstance() to ensure that the singleton design is correctly applied. Be aware that FontConfig lookup is disabled by default. To enable, call vtkFreeTypeTools::GetInstance()->ForceCompiledFontsOff();

Creates a new object of this type, but it is not preferred to use this method directly. Instead, call vtkFreeTypeTools::GetInstance() and let the object factory create a new instance. In this way the singleton pattern of vtkFreeTypeTools is preserved.

static bool vtkFontConfigFreeTypeTools::LookupFaceFontConfig	(	vtkTextProperty *	tprop,
		FT_Library	lib,
		FT_Face *	face
	)

static

Modified version of vtkFreeTypeTools::LookupFace that locates FontConfig faces. Falls back to the Superclass method for compiled fonts if the FontConfig lookup fails.

FT_Error vtkFontConfigFreeTypeTools::CreateFTCManager ( )

protectedvirtual

Reimplemented from Superclass to use the FontConfig face lookup callback.

Reimplemented from vtkFreeTypeTools.
