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.

I cant read in French (I believe it was French) but I have read some manuals of course.

It is really good idea to seek out how it this done in other plugins. Maybe the gimp has own friendly way how to do this.....

What I don't understand is what is the "base" or "working" directory of gimp. And without this it is really hard to consider relative paths. Moreover, working directory can differ based on way how the gimp was launched (probably).

Bonjour,

Some ideas :

gdk_pixbuf_new_from_xpm_data ()

Yes, I know about this, but this solution seemed to me too complex. But I would avoid a lot of problem.
I will investigate this....

I did some investigation,

I did some investigation, first from your example and then from gdk-pixbuf Library page.
It seems there are two similar ways possible, first one is the one in your example - gdk_pixbuf_new_from_xpm_data and second is gdk_pixbuf_new_from_inline. I dont see any significant difference between them...

I will have to learn how to place the image data into separate header file (should be easy).... should be done in few days...

Is I said few times, there is lack of howto/developers tutorials in this area of programming...

Gimp 2.6.11 on Mac OS X 10.4

Can I install this plug in on my system?

Im not familiar with Mac OS X

Im not familiar with Mac OS X at all. Did you try the procedure in attached README.txt - copied below. This is the procedure for linux but perhaps...

gimptool-2.0 --install saturate.c

Let me know if you succeeded, I would mention it in the README file.

(of course the *gz package must be unpacked and you must be in the directory with saturate.c file)
