I have a gut feeling that what you really want is http://scantailor.org/.

Dear Sirs,
I wrote to the List Maintainers with my query and was directed to register with the List and ask my question to the List Members. The following was my email-query to the maintainers: ------------------------------------------------------------------------ I have been using Debian/Knoppix and GIMP for nine years now. While GIMP helps me a great deal in my very limited photo- and picture-editing works I still don't know whether GIMP has automated macro / batch processing.
There are some work that need to be automated. Like, I scan a book and wish to split the scanned left-right pages separately into a left page and a right page during post-processing. Now if I have scanned ten pages, I would like to do likewise for all the ten pages.
In this regard I need to write a macro/batch processing that would help me achieve this with the click of a Run button during post-processing.
I have not yet joined a forum or the mailing list. If my needs could be fulfilled I would then like to join a mailing list. Otherwise, posting my needs to the mailing list would be a distraction for the list members.
------------------------------------------------------------------------ Eager for your advice.
Regards,
Rajib

Sir,
Doesn't GIMP have such tools as I have mentioned that I require - like batch processing / automated macros for a series of files?

GIMP doesn't do macros recording. You'd have to write scripts in an interpreted programming language.

Dear Sir,
How to write scripts in an interpreted programming language which could use GIMP?
Any advice? Any example?

https://docs.gimp.org/2.8/en/gimp-using-script-fu-tutorial.html could be a start.

Will this query be considered off-topic?

Probably not? Frankly, I have no idea.

Alex

If all you have are 10 pages it is faster to just do them manually. If you have many more pages, scripting in Script-fu may be the way to go. I know nothing about Script-fu but I did find this site. If you know programming or scripting it may be of use to you: http://gimpbook.com/scripting/ .

It comes from a book which may be useful to GIMP beginners generally. "Beginning GIMP: From Novice to Professional ... by Akkana Peck"

Good luck. Rick S.

Dear Sir, Thank you for your quick and informative reply. I am encouraged to ask: Is there a Script-Fu forum? I found some posts in Ubuntu:Forum by Google search with the string, "script-fu forum linux" but they are threads.
Any dedicated forum for Script-Fu?
I have perused your link. It gave me an useful lead. I then found the link: https://docs.gimp.org/en/index.html , and reached the following, but did not come across any relevant example:

13. Scripting ...
2. Using Script-Fu Scripts
2.1. Script-Fu?
2.2. Installing Script-Fus
2.3. Do's and Don'ts
2.4. Different Kinds Of Script-Fus 2.5. Standalone Scripts
2.6. Image-Dependent Scripts

3. A Script-Fu Tutorial 3.1. Getting Acquainted With Scheme 3.2. Variables And Functions 3.3. Lists, Lists And More Lists 3.4. Your First Script-Fu Script 3.5. Giving Our Script Some Guts 3.6. Extending The Text Box Script 3.7. Your script and its working

Could you (or any kind-hearted individual) provide any idea or feedback about http://gimpchat.com ?

What I need is a script as follows: I have a book that I have scanned. It has both the left page and the right page.
When the script is run, it will open a copy of the file in a new window and first select the right page, wait for minor alterations in selection, when done, will delete the selected area and autocrop the image to have the left page. Rename the page as "file name"_left.jpg and close the new file.
Then it will open another copy of the file, select the left page, ait for minor alterations in selection, when done, will delete the selected area and autocrop the image to have the right page. Rename the page as "file name"_right.jpg and close the new file. Any advice?
Regards

I would certainly recommend you post your requirement at GimpChat as there are a few people there who could create the script you require.

You have many examples installed with your Gimp, since Gimp itself uses scripts. Look into /usr/share/gimp/2.0/scripts

You can also write scripts in Python. See https://www.gimp.org/docs/python/index.html

Some examples of Python scripts here: http://sourceforge.net/projects/gimp-tools/files/scripts/

You may also find this useful, as you are working with a Linux OS:

https://www.imagemagick.org/Usage/crop/

Imagemagick is a very versatile tool for doing repetitive operations on images. In your use case, it would be possible to run the program twice, to save cropped copies of the right half of every image, then save copies of the left half of every image.

Determining the exact commands to use takes a little digging in the documentation, but that's way easier than learning Scheme (or so I imagine, not having learned Scheme myself).

If your scans don't need tweaking, and your target output is a PDF document, Imagemagick covers that in one operation:

Oops, that's how to do the opposite thing: Convert PDF to image files with various tweaks. Here's something more like what I intended:

convert *.jpg [output].pdf

Combining a large number of big images into one PDF file takes a lot of resources and may even fail if your system is not very powerful. For those cases, this little script will do the job:

for f in *.jpg; do
convert "$f" "${f%.jpg}.pdf"
done
pdftk *.pdf cat output combined.pdf/

(Needs the pdftk "PDF toolkit", available in all the major Linux repos.)
