Zoom out of astronomical image preserving header info [message #42625]

Ciao,

I need to zoom out an astronomical image, in order to make it visible a
part of the sky which is NOT included in the image itself. In other
words, I need to display the original image in a smaller region of the
picture and the rest is black. BUT, I need to preserve the RA and DEC
coordinates in the black part of the picture, because I have to draw a
box at certain coordinates to show that it is well outside the original
image. Moreover, I need to put RA and DEC axis (as it's done with
imcontour), BUT for all the total picture, not only the original image.
I hope it's clear! In any case, I've done it succesfully with ds9, so
that I can show what I want to you, but in IDL the result can be much
better!

Thank you very much,

Stefano
