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();
