Open the isv in an itool (in Windows, double-clicking the file should
do it, or just open any itool from IDL (a simple iplot in the command
line is enough, it does not matter which itool made the isv file)).
Then select the image you are interested in, and use File->Export data
to IDL (I think before IDL 7.1 it used to be in File->Export->To an
IDL variable). You can then select to export the image (imagepixels)
and/or the palette, and pick the name of the variables where they are
put (they default to image_planes and palette).
