who can help me on the function:  
 SCREEN(windowPtr,'PutImage',imageArray,[rect],[copyMode])  
I just don't know how to create imageArray. How is the imageArray related to   
the image? what is the meaning of the value of the array. for   
example,imageArray(3,3)=5, what is the meaning of 5?.  
If anyone can provide the source code of screen function, it'll be highly   
appreciated.  
  
thanks,  
  
buell
