You can export settings of a Color Curves Settings to a file by:
clicking top right little arrow then choose Export Settings to File...

then save it as a file under Gimps/curves folder.
You can then import this file whenever you want to load up those same Color Curves settings.
This python plugin will allow you to select an exported curve file as input and apply it to the currently active layer/or selection.

It'll be availabe under Filters/Apply Curve... (just extract the zip it and toss it in your Gimp's plug-ins folder)

This came about because currently, I couldn't find away to apply a saved preset curves settings from Script-Fu. So i hunted for code on the internet and found some code written by Raymond Ostertag for batch processing curves on a whole set of images (https://github.com/alessandrofrancesconi/gimp-plugin-bimp/issues/83). So i extract some of his code and made this .py file.

Now people like myself can have access to applying an exported curve file from script-fu by calling

the 1 just indicates that it runs NON-INTERACTIVE

Here's a sample .scm file that calls python-fu-apply-curve.

I thought this problem sounded familiar: http://www.gimptalk.com/index.php?/topi ... it-curves/

Nice to see it done in Python though.

Only because i found code in Python... I really don't like the fact that everything time you change anything that has to do with the registration of a python script that you have to restart Gimp... if only there was a refresh similarly to scheme scripts i would then do python more often
