WSIZE sets the size of the Image window. Optionally, it positions the window at x and y. Some window managers might not support positioning.

Example

Make the Image window match the size of the image that is being displayed:

main:
   height=0;
   width=0;
   rc=imgop(task-id,'READ',path);
   rc=imgop(task-id,'QUERYN','WIDTH',iwidth);
   rc=imgop(task-id,'QUERYN','HEIGHT',iheight);
   rc=imgctrl(task-id,'WSIZE',iwidth,iheight);
   rc=imgop(task-id,'PASTE',1,1);
return;
