You might have a look at the IDL astronomy library if there is something
like that already there at
http://idlastro.gsfc.nasa.gov/homepage.html

> 2. graphic editing (paint, flood fill, zoom, etc.)

A seedfill routine and maybe other graphics related stuff is contained in
the JHU/APL/S1R IDL Library. See ftp://fermi.jhuapl.edu/www/s1r/idl/idl.html.

> 3. Display JPEGs

You can read and write JPEGs using idl procs read_jpeg and write_jpeg. See
user guide chapter 16 (Image Display Routines) how to display them on your
graphics device once they are read into idl arrays.

Regards,

Christian
