Re: [Gimp-user] How to treat several pictures at once?

2004-02-06 Thread David Hodson
Dirk,

I took a series of pictures (measures) and I have to normalize and 
equalize them to see any result. [...]

Any help, tutorial or hint would be cool because it is quite urgent.
I've got a batch processing plugin at:

http://members.ozemail.com.au/~hodsond/dbp.html

It applies some common operations to a collection of images.

It doesn't do equalisation, but it has brightness and contrast, so
if the adjustment is the same for all images you might be able to
use it.

Assuming it can do the job (and it can do a lot of jobs), your best option 
is probably not the GIMP, but rather ImageMagick, which provides set of 
command line tools for doing all sorts of image operations.
 
You mentioned normalizing and equalizing.  To do that with ImageMagick, you 
would just run, e.g.:

mogrify -normalize -equalize *.JPG

Done!

If you find that ImageMagick won't do it, then you should look into 
scripting the GIMP.  I recommend writing your scripts in Python, but it 
really depends on what you're most comfortable with -- or most interested 
in learning.

Shawn.

[Gimp-user] How to treat several pictures at once?

Hi there,

I am a new gimp user as well as a new list member. I have got the following 
question: I took a series of pictures (measures) and I have to normalize and 
equalize them to see any result. Is there any perl skript or smth. else that 
does this step with all the pictures I have because it is impossible to treat 
~ 50 pictures seperately (no time ...) I have never used perl, so I also do 
not know how to use it with gimp.

Any help, tutorial or hint would be cool because it is quite urgent.
