Clientside TDrawingPanel

[fowlplay4]

Well I decided I would experiment with it today but I just can't get it to work.

PHP Code:

//#CLIENTSIDE
function onCreated() {
  temp.panel = new TDrawingPanel();
  temp.panel.setsize(getimgwidth(player.head), getimgheight(player.head));
  temp.panel.drawimage(0, 0, player.head);
  temp.panel.saveimage("test.png");
  temp.panel.destroy();
} 


The error.

GraalScript: Couldn't create object: type TDrawingPanel is not existing in script of Weapon Jerret/Debugger

Edit: I was able to find success with GuiDrawingPanel but I'm still curious as to why the above doesn't work.
