Hi Everyone,
I am struggling with IDL and I am ready to through my PC out the window.
Please help me, so we can save this machine! :-)
I am despearetly trying to use MAP_SET and MAP_IMAGE with Postscript device,
but every image that I TV is just white. Does anyone have a working example?
(I know that it would work if the image is created before switching to the
PS device, but, trust me, this is completely unfeasible in this piece of
code.) Any help is greatly appreciated.
Haje

No, it's never happened to me. :^)
Cheers,

David,
sorry about the panic. I just found out about the /noerase keyword in
map_set. Since I write the headeline of the plot first, the routine created
a second page in an eps file, which you never ever get to display! So, I was
able to fix the problem. (I accidentially looked at the footer in gsview and
it said page 1/2; this gave me the hint.) Since my page was all white, I
thought that I was positioning wrong! I was barking up the wrong tree for
two hours. ...and as you can imagine, you can get pretty mad in such a long
time. I actually had to close my door not to upset my neighbors! :-)

Oh, dear! Could we just have a peak at your code to
see what it is you *think* you are doing? :-)
I'm particularly interested in how you are setting up
the PostScript device and how you are "creating" the
image.
Cheers,
David
