Only cover the basics; these are powerful tools!

The GIMP

[GIMP]

GNU IMAGE MANIPULATION TOOL: the GIMP
Built on GTK+, aimed at Unix/Linux/X11 (soon Windows too)
Installed on Linux/CV (may want gimp-data-extras)
File -> New or Open to start.
Right Click for many things.
Ultimate Reference: GIMP.Org.

GIMP - Use it for This Stuff

Annotating Images (from this to this)
Almost anything to do with Web Graphics
Publication Quality Image Manipulation
For best print results, assume 300 dpi, do the math!
Examples:
- Book Cover (layers, transparency)
- Edgemont Road Photo (drop shadow)
- Cygnus/GBT Image (text, titling)
- Various NRAO Logo variants: shiny, goldstar, Millner/Bridle.

Xfig - Figure Drawing

Start at command prompt: xfig
Drawing, Editing modes on left
Mouse Button chart on top right
Like vi: lots of modes
Extra options at bottom, depending on mode

Xfig - what it's good for

Making charts like this
Line drawing, postscript manipulation
Enhancing AIPS output plots (use OUTPRINT)
Printouts that need scalable fonts
Some nits: WYSINAWYG (what you see is not always what you get), but this is improving.
Linux version much more recent than Solaris (in CV).

Conclusions

The GIMP and XFIG can handle most graphic/image tasks
Recommend use on Linux (part of the system, upgrades etc)
Use the right tool for the job
Many other tools (xpaint, ee, gqview, xv...)
