I tried that sample and image by RobA, nothing is happening, I didn't get any kind of dialogue. I deleted his script, went to latest gimp scripts above... and I now get a dialogue when I right click the gradients. That is as far as I can get... I dont get a new image when I do that, it just goes to one of the gradients already in the list. I opened a picture and tried to make a gradient from it and I get a gradient already on the list.

I noticed that when I right click and choose sample along gradient, the dialog appears behind GIMP. I don't know why that happens but I have to move to my task bar and select it to bring the dalog to the front.

So, first I use the path tool to create a path over the image I want to sample, then right click on the gradient dialog and select Sample Gradient Along Path. I bring the dialog to the front, and enter the name of the New Gradient. I increase the Number of samplea to 256, ensure I have the correct image/drawable/path selected and click OK. It then creates a new gradient in the list with the name I specify.

Those are very nice tux, it works like a charm for you.

This is really useful.

Doesn't the Sample Gradient Along Path script do the exact same thing? It's easy to use.

Tux, this is what I started with and ended up with. I didn't get that nice strip that you have.

I have the best gradient maker I have ever used over in windows. I don't think I can get it in Fedora but if anyone can identify this language, (I think it is Dutch) I would like to look it up. ...

Is this the one:

Does not look like it will be available in linux anytime. maybe it works in WINE.

It is not the same one Rich. The one I have has a Polish home screen, the one I posted in the first post on this thread.. It is so easy peasy. I never thought of wine, that might work for the one I have in windows, I dunno

Molly, it looks like it worked like it was supposed to for you. You will probably need to lower the number of samples because there are so many subtle color changes in your image. If you set the samples to 256 you might get 256 different color changes in your gradient, with that image. Try experimenting with lower numbers, even 10 or below and you'll get less of the subtle color changes and smoother transitions in your gradient.

The line I posted was just a selection filled with the sampled gradient, so I could see what it looked like in action.

Ok, I will start over. funny, I only had the tiniest piece of the orange selected and that gave me the widest section. :tyspin

Edit: Molly's pink flower gradient.

It is called ChangeImage

http://registry.gimp.org/node/25571

This is the splash in a little linux netbook. Unfortunately it crashes later on when trying to save the .ggr file.

For the clever people here, there is a python script about halfway down this page.
http://www.gimpuj.info/index.php?action ... ic=52156.0

Code: Select all

#!/usr/bin/env python
# -*- coding: utf-8 -*-
# The idea taken from RobA Shellout http://registry.gimp.org/node/24977
# GradientfromImage by Krzysztof Zaj\u0105czkowski  http://registry.gimp.org/node/25571

from gimpfu import *
import shlex
import subprocess
import os, sys

def plugin_main(img, drawable):
  command = "\"C:\\Program Files\\GradientfromImage\\ChangeImage.exe\""  #<<--EYTUJ \u015bcie\u017ck\u0119 do katalogu programu ChangeImage.exe
  args = shlex.split(command)
  child = subprocess.Popen(args, shell=True)

register(
        "python_fu_GradientfromImage",
        "Gradient from Image",
        "Gradient from Image",
        "www.gimpuj.info",
        "MareroQ for Ma\u0142yszKZ",
        "2011",
        "<Image>/Edit/Edytor gradient\u00f3w z obrazka",
        "*", 
        [],
        [],
        plugin_main,
        )

main()

Might give this a try when back on my regular machine.

This bit is looking for a windows executable. It's not going to work (natively) in Linux.

I have just got that ChangeImage working in my little Acer netbook (Bodhi linux).

Took a bit of tweaking in WINE - had to get a new msvcp90.dll file to fix the 'crash' (app freezes)

In my regular machine (PClinuxOS) I have shellout and XnView installed and working, so I might see if I can call ChangeImage from Gimp via shellout. Maybe tomorrow
