Scales the coordinate system rather than the object itself. This affects not only x and y coordinates when placing shapes but the width, height, line width and radius of shapes as well.
In the example below, the coordinate system is scaled up by a factor of two each time. Note how the circle placement, the radius and the line width also change.
// start a PDF document $cpdf = cpdf_open(0, "test.pdf"); // create a 600x400 page cpdf_page_init($cpdf, 1, 0, 600, 400, 1); // draw a circle cpdf_circle($cpdf, 50, 50, 10); cpdf_stroke($cpdf); // scale coordinate system and draw circle cpdf_scale($cpdf, 1.5, 1.5); cpdf_circle($cpdf, 50, 50, 10); cpdf_stroke($cpdf); // resale coordinate system and draw circle cpdf_scale($cpdf, 1.5, 1.5); cpdf_circle($cpdf, 100, 100, 10); cpdf_stroke($cpdf); // close and write document cpdf_finalize($cpdf); cpdf_close($cpdf);
