Call cairo_recording_surface_create with second argument equal "NULL".<br> </div> <div><br> </div> <div>2. Draw the figure.<br> </div> <div><br> </div> <div>3. Measure the figure using "cairo_recording_surface_ink_extents" or "cairo_recording_surface_get_extents".<br> </div> <div><br> </div> <div>4. Shift and scale figure as appropriate for final rendering.<br> </div> <div><br> </div> <div>In my attempts to follow this strategy produce nonsensical results for both options in item 3.
