Example
Example 126. Draw two filled curves
// start a PDF document $cpdf = cpdf_open(0, "test.pdf"); // create a 600x400 page cpdf_page_init($cpdf, 1, 0, 600, 400, 1); // move pointer cpdf_moveto($cpdf, 300, 100, 1); // draw first curve and stroke cpdf_lineto($cpdf, 350, 100, 1); cpdf_curveto($cpdf, 350, 100, 325, 300, 300, 100, 1); cpdf_stroke($cpdf); // move pointer again cpdf_moveto($cpdf, 200, 50, 1); // draw second shape and stoke/fill cpdf_lineto($cpdf, 250, 50, 1); cpdf_curveto($cpdf, 250, 50, 225, 200, 200, 50, 1); cpdf_fill_stroke($cpdf); // close and write document cpdf_finalize($cpdf); cpdf_close($cpdf);
