Saturation Equalizer
May 7, 2011 - 21:39 — Tibor95
Saturation equalizer is saturation plugin that can adjust saturation of an image via 6 sliders – effectively the saturation curve. You can alo modify brightness of image with two spinboxes – they work like „levels“ tool.
Additionally you can autoalign RGB channels to eliminate color cast and there are few more features. I believe they are self-explanatory, once you work with plugin.
It internally works in floats, that means no information is lost during processing.
Plugin is multithreaded.

saturation equalizer 0.7
Hi, I have new version of my plugin. If I ignore development versions (not published here) changes are
- multithreading
- sliders coupling (you draw one slider, other follows in some distance)
- masks (Not related to saturation, but it seems usefull to me)
- preserve color (hue) button - It limits saturation boost of a pixel, if some of RGB values is to get out or range (and be cropped and this way it would change color (hue) of pixel)
- resizeable (expandable) preview
- GUI reworked (was necessary as there are much more options now)
Lately Im thinking if the plugin doesnt became too bloated. But as I have no feedback in this regard from users, I follow the rule "What is good to me, is also good for others". :)
So enjoy this my little work and whatever you have to say to me, dont hesitate....
Regards

Bonjour,

For the icons in the plugin, place the directory "satequalizer" which contains 4 images png in C:\
(result C:\satequalizer)
Thanks Tibor for the update
Thanks Tibor for the update and samj for the windows compile. Much appreciated. :)
Thanks again! Really useful
Thanks again! Really useful ideas (sun filter, slider coupling and of course expandable preview)!
One curious issue: the sliders are not in line, but are slightly ascending to the right :)
Thanks for positive feedback,
Thanks for positive feedback, owl_2 (and lylejk as well).
To your question about ascending sliders.. yes, but this is rather side effect of a feature than bug. My idea is that less saturated areas would have bigger upper limit for saturation boost - in plain language, maximum value of sliders differs -move them to the top and see values above them.
Of course, this detail whether all sliders have to have the same max values, or more important question - what should be maximum values of sliders are quite subjective... The numbers came to existence when I started coding this plugin and needed some numbers to put there. And then I just did not feel any need to change them.
You were fast, thanks. But is
You were fast, thanks.
But is it necessary for a user to MANUALY create that directory and copy those png there? In linux any package manger can take care on this and place any files anywhere - unless there is a conflit - f.e. if it tries to overwrite existing files.... I cant believe that windows cant do this...
But I just want to emphasize that plugin will work withouth those images, just user will see only "broken image" placeholders instead...

Uable to create c:\satequalizer. I'm not allowed to create a rootdir because I'm no admin. Can you modify it to the Gimp-plugins directory??
Modification directory
Bonjour,
@ E. Sullock Enzlin
I'll see if I can modify the source code to no longer use the absolute addressing.
@ Tibor95
It would be a good idea to use relative addressing for images directory.
The user just needs to drag the folder from the archive with the file explorer .
"It would be a good idea to
"It would be a good idea to use relative addressing for images directory." - this is GTK+ issue, but I will investigate what can be done with this...
I believe installation should be as trivial for user as possible. Also, what in case of uninstall, who will remeber what files and where did he ever copied during installation of various packages?
It would be best if these images were directly compiled into binary, but i dont know how to do it, and if it is possible at all.
All right, as I said, I will check what can I do with this problem

I will continue to look for another example of a plugin. I have already compiled one with an embedded picture but I can not remember its name.
There is also a logo in GMIC.
