automating a filter

[sierratango]

I would like to create a series of images by systematically varying just one parameter of a filter (e.g., changing the X1 or X2 input to Fractal Trace). As a GIMP beginner, it appears to me that for each new image, I have to re-open my source image, make all the initial parameter selections, change the value of the selected parameter, and then export the image. Is there a way to automate this process or at least to minimize the number of manual inputs?

You don' t have to reopen, you can Ctrl-Z or at worst use File>Revert if you don't export to the source image. You can also reopen the last-run filter dialog with Ctrl-Shift-F, so you would have to only change one parameter.

I don't know of any one-to-many filter runners, all those I heard of apply the same set of parameter to multiple images.

I can post later some code that you can run in the python console if needed. What combination of ranges do you want to try?
