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.

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 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.


Paul.

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 ?
