* HELP *
All you Postscript/NeWS experts out there-- I need to know
what's going on with imagemask. When I execute the following
fragment of Postscript code in the NeWS psh environment......
100 100 translate
400 400 scale
0 1 0 rgbcolor setcolor %green
900 900 % width and height of bitmap
true % color if bit is set to 1
[900 0 0 900 0 ] % starts in lower left hand corner
{<
(202500 hex characters arranged in rows of 72
characters each except the final row has 36)
>}
imagemask
....... the image, that should look(generically) like
this_
|

\|/

# ### ### # # ### ### #
# ### ### # ### ### # #
# ### ### # turns into # ### ## ##
# ### ### # something like--> ## ## ### #
# ### ### # ## ### ###
# ### ### # # ### ### #
Is there something obvious that I am overlooking? I'm fairly
certain the bitmap itself is correct in the sense of scanning
left to right and up by rows from the lower left hand corner
of the image.
Thanks,
-Malcolm.
