A simple for loop while using Colorize

I'm looking to loop through and generate individual images by changing the "Hue" variable by 1 (ideally going from 1 - 360) and saving the resulting image.

So, my process is like this:

1. Set x to 1 2. Apply Colorize with Hue = x (all other values are at their default) 3. Save image as x.png
4. Undo to previous state.
5. Increment x by 1
6. Repeat steps 2-5 until x equals 361

What would be the best approach to accomplishing this?

Thanks, Tim

A small script written in Scheme or Python would be the best way to do the above. Doing it by hand will be very tedious. As I suspect you are about to say you wouldn't know how to write such a script, you would have to see if you can talk someone in to writing such a script for you.

BTW, hue values range from -180 through to 180 (inclusive) in GIMP.

Try this plug-in I threw together: http://registry.gimp.org/node/24963

A simple for loop while using Colorize

I was aware of scheme scripting, but not of python. I'll have to look into that. It shouldn't be too difficult.

However, I was going off of the "portable apps" version of GIMP as I was writing, which went from 0 to 360, not -180 to 180. Is that a version difference?

Wonder if this couldn't be done with GAP?  If so, it would be trivial to do, just load the original, duplicate it enough times to get 360, then run through the frames with "apply filter varying".

If you are using a portable version of GIMP, the files needed to support Python scripts are probably not available to you.

The -180 to 180 for hue is the range of the sliders in the GUI and is listed as the range in the Procedure Browser text in GIMP 2.6.7 (and later). The current version of GIMP as a portable app is 2.6.11 so it will have that same range.

The portable version was only temporary, as I was on a different computer. I have it installed at home. I'll try scripting with Google and python.

I have never herad of GAP, and thus enver used it. It does look impressive though, and I'll have to play with it at a further date. Tim Butram
