- * Note: When printing a DWrite font to a

- * will substitute each DWrite font with a Win32 font created from the same
- * underlying font file. If the matching font file can not be found,
- * the #CAIRO_SURFACE_TYPE_WIN32_PRINTING surface will convert each
- * glyph to a filled path. If a DWrite font was not created from a system
- * font, it is recommended that the font used to create the DWrite
- * font be made available to GDI to avoid the undesirable fallback
- * to emitting paths. This can be achieved using the GDI font loading functions
- * such as AddFontMemResourceEx().
- *
- * Return value: a newly created #cairo_font_face_t. Free with
- *  cairo_font_face_destroy() when you are done using it.
