Yes, this is quite a common feeling when you are
on the rising trajectory of your career. Later on,
MatLab starts to look better and better. :-)

haha yes, a lot of conditions.
Dr. Fanning, you are awesome and that is brilliant! Appreciate the
time and thought. Over the past couple of weeks, I am realizing how
powerful IDL really is, it is quite an amazing piece of software...

OK, I thought about this the whole time I was taking my
shower and I've come up with what I think is a brilliant
solution.
PS_Start, File='example_wo_tvrd.ps'
TVImage, LoadData(7), /KEEP
XYOUTS, 0.5, 0.5, /NORMAL, 'This is some text', FONT=0, CHARSIZE=2.0
PS_END, /TIFF
You will find the file "example_wo_tvrd.tif" in your
current directory. It will have text written on the
image!
Cheers,
David
P.S. Of course, I *assume* you have ImageMagick installed
properly.

OK, and you have religious reasons for not wanting to
use TVRD, right? Humm.
You remind me of of my youngest son. He sets up all these
conditions that make a job almost impossible to do and then
he seems surprised when he can't get the job done.
Let me ask you this. What connection do you see between
pixels that have changed color on your display and the
image variable you are writing to the TIFF file?
Cheers,
David

haha nothing like that :).
I have an image, where I have written text using XYOUTS. When I save
the image as a TIFF, the XYOUTS do not show in the image. Anyway I can
make them show when I save the image?

Maybe you should explain what you it is you really
want here. You wrote something on your image, and
now you wish you hadn't, or what? Maybe something
critical of the boss?
Cheers,
