swf_ortho2 — Define 2D co-ordinate system


void swf_ortho2(xmin, xmax, ymin, ymax);
double xmin: X-axis minimum
double xmax: X-axis maximum
double ymin: Y-axis minimum
double ymax: Y-axis maximum




Creates 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_ortho2() 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 100x100 pixels with an origin startting in the middle of the square. This means that the displayed text is displayed at 0,0, or at the centre.

This function differs from swf_ortho() in that in only operates in 2 dimensions.
