Current definition of offscreen functions defined using "#define" makes difficult to call them from different functions. So, from thread where geometry can be calculated and prepared for complex line visualization we cannot set vertex by vertex into offscreen drawing.
Current definition requires all drawing functions to be set between fl_begin_offscreen() and fl_end_offscreen(), otherwise source code cannot be compiled.

Please use class Fl_Image_Surface instead which is also available in FLTK 1.3.4 (or even lower).

If this doesn't help with your issue please feel free to open a new STR.

Closing this STR.
