Forget the question, ignorant old me has sorted it out.

That will certainly be my goal, but I still expect to find some hiccups 
or interface inconsistencies. If I'm lucky, I won't need this list, but 
if not, I want to know the most important batch functions for me to add. 
In fact, my goal is to create a plugin that scans the undo history for 
the current image and allows you to apply those changes to a whole bunch 
of images. Now that would be slick.

I would like to try this idea but I am not sure how to copy a layer into
a mask. I have tried various things and even referred to the help file
with no success. Could you please explain to ignorant old me what to do?

Evan,

- a _pause_ for subjective actions

One action I use when I make a python script for batch manipulation is a
_pause_ where I can make subjective decisions like cropping and then
click go, where the python script returns to the automated actions like
uniform resizing etc, then it brings up the next image, automated
actions, stops again for me to crop etc.

This should actually read '0.2'. ('0.35 ... 0.50' are the
values I use for the final 'Unsharp Mask'.)

I have never done this sort of thing but, from what I have learned, the
last thing I would do is sharpen the image and the step before that
would be to size the image.


I personally would really like to have

a) Resampling
b) 'Smart' Unsharp Mask

available, which I use quite frequently.

The latter is an advanced  'Unsharp Mask'
technique, which goes as follows:

1.) Decompose the image to HSV
2.) Select the 'V' layer
3.) Copy this layer into a mask
4.) Perform 'Find Edges (Sobel)' on the  mask
5.) Perform a 'Gaussian Blur' (value: 0.35 ... 0.50)
on the mask
6.) Mask -> selection
6.) Delete the mask
7.) Perform 'Unsharp Mask' on the now-selected 'V' layer
8.) Compose the image back to RGB

The results one gets when using this technique are visibly
better than a mere 'Unsharp Mask'.

Greetings,

Claus

Have you seen David's Batch Processor at
http://members.ozemail.com.au/~hodsond/dbp.html ?

If you like, I could give you a list of functions that people have asked
me to add to it.

I have never done this sort of thing but, from what I have learned, the
last thing I would do is sharpen the image and the step before that
would be to size the image. What you do before that is up to you but you
certainly should crop early in the process.

Hope this helps.

[Gimp-user] Batch tool suggestions?

2009-04-09 Thread Evan Kroske
Hello GIMP users,
I'm going to be developing a batch image processor plugin for GIMP, 
and I'd like to know which functions should be the first on my list. 
Obviously, scaling is the first priority, because I use that to optimize 
pictures for my websites. However, past that, I'm not sure which 
functions are the most used. Should I add ...
... cropping?
... layer management? (eg. adding a layer with a signature to a whole 
bunch of pictures)
... filters?
... color management?
... or something else?
I would like to add all of those functions, but I will probably only get 
two or three of these actions enabled. What are the most important 
functions for you?
