swf_orthoDescriptionCreates a co-ordinate system inside the SWF background for manipulation and transformation of objects. Normally the X and Y axis starts from the bottom left corner. Using swf_ortho() the co-ordinate system can be redefined indpedent of where to co-ordinates usually start and the dimensions of the file. In the example below, a SWF file 200x200 pixels is adjusted to have a co-ordinate system of 100x100x100 pixels with an origin startting in the middle of the square. This means that the displayed text is displayed at 0,0,0, or at the centre. ExampleExample 1272. Modify 3D co-ordinates swf_openfile("test.swf", 200, 200, 30, 0.8, 0.8, 0.8); swf_addcolor(1, 1, 0, 0); swf_definefont(1, "Pix3"); swf_fontsize(10); swf_definetext(2, "Hello World", 0); swf_translate(0,50,0); swf_placeobject(2, 1); swf_showframe(); swf_ortho(-100,100,-100,100,-100,100); swf_definetext(2, "Ortho World", 0); swf_placeobject(2, 1); swf_showframe(); swf_closefile();
