Image conversion package required

Does anyone know of a package which has a non point and click interface to
 manipulate images.
The reuirement is basically to ask an image its size, type etc and then to
 create an image in a different format and to automate this.
There are obviously plenty where a mouse is used but it would be nice if one of
 these had a small language of it's own.
I apologise if this question has been asked before but there around 2500 items
 in this group and I have no seach facility within AOL newsgroup reader.

netpbm is THE standard tool for this. :-)

It really is a great package & a great way of doing things, I just wish
it was as common as vi. :-)

I highly recommend it, even if you do have a GUI.

Several:
net-pbm.

Image-Magic, Xv.

Yes, I know, the last two have a gui-interface, but are also usible
from the command-line.

1. Batch image conversion program?

I wrote such a thing in Tcl using ImageMagik's convert program:

#!/usr/bin/tclsh

foreach jpg [glob -nocomplain *.jpg] {
  set gi  "[file rootname $jpg]_I.gif"
  exec convert -geometry 10%x10% $jpg $gi

With Tcl installed, you should be able to do:

man n foreach
man n glob
man n file
man n exec

and with ImageMagik installed:

man convert

To get documentation on the functions used above.
