Hi,
	I had strted on X windows(Open Look 2.0) recently and I am working on
 Image package and not sure how to do the following, can some one help me on 
this.
 I want to acess pixel information of an image and manipulate them for writing 
Image processing routines. I dont want to use XPutpixel etc as that slows down
the whole thing, is there any way I can assign a arry containing the pixel 
values to the data of the image.

	what I am looking for is something like assigning memory pixrect in
Sunview.
(i.e) equivalent for 
	mpr_d(mem)->md_image =(short *) buf;
where buf is an array containing the pixel values and mem is a memory pixrect.
	
		Thank you.
					Sincerely
					Shyam Kotha
