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();

Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.

Reimplemented from vtkFreeTypeTools.

virtual void vtkFontConfigFreeTypeTools::PrintSelf	(	ostream &	os,

virtual

Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.

Reimplemented from vtkFreeTypeTools.

static vtkFontConfigFreeTypeTools* vtkFontConfigFreeTypeTools::New ( )

static

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.
