color bitmaps?

   Subject:      color bitmaps?
I have a 700 by 700 array of bytes which I want to display as a grey scale
image.  (Actually, what I really want to do is print it out, but if I can
display it I can print it.)  Is there a FAST way to do this in MACL?  The
obvious thing of doing a set-fore-color followed by a line-to for each pixel is
painfully slow.  Is there such a thing as a color bitmap that I can just plop
into a window using quickdraw?

Thanks,
E.
