I accidentally discovered 'convert'. It is a command line utility. Changing a file from png to gif works like this
convert aaa.png aaa.gif
Amazingly simple, powerful and effective.
I've since discovered it has an amazing list of options
convert --help
a manual
file:///usr/share/doc/ImageMagick-6.2.8/www/convert.html
and a web site
Does anyone have suggestions for a GUI which works for Centos 5.6 ? In production I run the command line program from PHP with 'exec'.
Thank you,
Paul.
Currently automatically, rotating when necessary, downsizing photographs to 900 pixels wide (the software calculates the height) and labelling them with the file reference and photograph date - all in one quick operation. Mind boggling options, more than I've ever seen in similar software.
Really amazed :-)

imagemagick is a batch oriented utility. putting a gui wrapper on a batch program inevitably ends up with something clunky and not usable.
for GUI image editing, you want to use something interactive like Gimp.

I wanted to explore all the options and see the effects in a GUI application rather than laboriously type-in the parameters on the command line then double-click on the latest photograph to see the effects.

but there's a nearly infinite number of possible combinations of the options, and the order you specify transforms can have an effect on the output, how would you represent this in a GUI ?

Two possibilities come to mind. One, the display command, also part of the ImageMagick suite will display the picture. If you click on said picture, a menu pops up. In that menu are many options.
Second possibility, type in the commands and put all your output into one directory. When you've made your different pictures, install feh with yum install feh.
Then, you can type feh <directory_name> and hit the n (as in next) key. This will go through the pictures, showing a new one each time you hit the next key.
The real advantage of convert and other commands is the fact that they are typed commands. For example, at an old job, a graphic artist was given a bunch of pictures. She had to resize them, often dozens at a time, and the only way she knew how to do it was in photoshop, one by one. Now _that_ was laborious.
When she mentioned it to me, I had her drop them in a directory on a server and I would run a script to resize them.
Anyway, good luck with it. The whole ImageMagick suite is extremely userful.

photoshop has a very powerful macro and batch facility. you can interactively create a complex series of operations as a macro, then run it on a bunch of files
but thats neither here nor there. certainly not CentOS related.

I am not writing a GUI for it. However a useful GUI could show the effects of making simple changes - perhaps one change at a time - not multiple changes. This would show new users what commands actually do and the relevant CLI instructions.
You are correct about the order of commands altering the output. The commands are performed sequentially, left to right. It is impressive software.

Sorry. Do you mean having a complete image processing toolbox ,like MATLAB image processing toolbox, on centos? Do we have such a powerful tool on centos?

I have experience working with MATLAB image processing toolbox. I found GIMP very powerful ,especially in its tools for 'selecting image foreground/background' that is not so simply available even in MATLAB toolbox. But unfortunately, my centos 5.6 built-in GIMP is too old (GIMP 2.2) that does not have these new tools. I didn't find any straightforward procedure on how to migrate to GIMP 2.4/2.6 . Don't you ?

ImageMagick includes its own GUI:
man display
And see:
man ImageMagick
for a complete list of ImageMagick programs.
The GUI is rather basic -- it is not meant as a anything like a replacement for the likes of GIMP or xv or any of the other other image display and manipulation programs out there. ImageMagick is meant to be a *CLI* workhorse.
Thank you,
Paul.

Thank you for mentioning Display ... a friendly wizard has appeared inviting me to experiment.
Previously I tried
man convert
but your suggestion of
man ImageMagick
gives a lot more information.
I use IM as an extremely useful CLI 'workhorse' via PHP Exec. With so many possibilities, it is very time consuming manually trying the effects from the command line interface.
My most recent achievement was to extract and superimpose the Exif date and time.

I upgraded from centos 5.6 to centos 6.0 to have all of the new featues on GIMP at hand. I selected Desktop when installing. But I don't see it under Applications -> Graphics as I had it under my previous centos 5.6 . Can you please let me know why?

yum install gimp

same as any other package.
CentOS6, I've noticed, installs a LOT less junk on the default installs.

You almost always want yum to resolve package dependencies for you instead of executing rpm directly for installs or updates. Rpm will tell you about the dependencies but not do anything else helpful like finding and installing the needed libraries.

And you really, really don't what to install *every* RPM on the install CD/DVD. In some cases there are 'mutually exclusive' packages (or pairs of packages where installing both makes no sense, like more than one SMTP daemon, etc.). Most of the time installing *both* mysql AND postgresql makes no sense -- you can do it and sometimes it is needful and proper to have two (or even more) database servers running at the same time, just most of the time most people are not going to do that. OTOH it can be useful to have a selection of PDF viewers or text editors.
