Since the graphic's coordinate system assumes (0,0) to be the origin, the page coordinate system is also translated to place the graphics not on the edge of the page. Pay attention to the order of ps_translate and ps_rotate. In the above case the rectancle is rotated around the point (100, 100) in the untranslated coordinate system. Switching the two statements has a completely different result. In order to output the following text at the original position, all modifications of the coordinate system are encapsulated in ps_save and ps_restore. &reftitle.seealso; ps_scale ps_translate
