I have a Postscript file containing some image data, and I would like to be
able to have the image drawn by a function.  However, the proc

	776 109 1
	[ 776 0 0 -109 0 109] 
	{ currentfile picstr readhexstring pop} 
	image

reads from the current position in the file (right after the call to the
function).

Is there any way I can store all of the hex image data in a big array or
something
and have the image procedure read it from there? What would the
procedure 
that's on the top of the stack before the call to "image" look like?
