Help, please.  I would like to define a command that includes an image
operator, but keep getting a stackoverflow.  The image data is approx 50k
and my printer has 2 meg in it (HP Lasterjet II with the Adobe PostScript
cartridge). This is what I would like to do:

/mypic {
	/dopic {
	gsave width height 1
	[width 0 0 height neg 0 height]
	{currentfile picstr readhexstring pop}
	image grestore } def
	0 0 translate pixwidth pixheight scale
	dopic
FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

...... picture data deleted

} def

then in several places in he document do a 

x y moveto mypic


Any hints/help/``this is impossible'' would be appreciated.

Thanks.

You can't do it this way.  "readhexstring" reads from the file, not
from the procedure body.
