This would require to create a new class, - say SVG_Graphics_Driver, derived from class Fl_Graphics_Driver, and another new class, - say SVG_Surface, derived from class Fl_Surface_Device. The new SVG_Graphics_Driver class should - implement all virtual methods of the Fl_Graphics_Driver class to support all FLTK drawing functions - and have them draw into SVG files. Alternatively, class SVG_Graphics_Driver could implement only some - virtual methods, and only part of FLTK drawing functions would be usable when drawing to SVG files. - The Fl_Graphics_Driver class is essential for developers of the FLTK library. Each platform supported by FLTK requires to create a derived class of Fl_Graphics_Driver that implements all its virtual member functions according to the platform. |
