Notes
 
     

This allows you to draw a string of Postscript onto the Canvas.  The postscript can be any Level 3 postscript as described in the 'Postscript Language Reference Third Edition' from Adobe Systems.

If the size of the canvas has not been previously determined, the Canvas will be sized as an 8.5 x 11 inch page with image width and height determined by the current value of the 'Res' parameter.

myps = "/Courier findfont 14 scalefont setfont 1 1 0 setrgbcolor"

ca.DrawFile Server.MapPath("Pictures/desert1.jpg", ""
ca.DrawPS myps, ""
ca.SaveAs Server.MapPath("Pictures/desert1Annotated.png"), ""
