Help with functions - chlebna - 10-21-2017
Hello,
do you know if it is possible to script funciton:
colors - desaturate - color to grey?
I didn t find it
as well as: colors- Color temerature
Thanks for your help

In python, either:
Code:
pdb.gimp_desaturate(drawable)
pdb.gimp_desaturate_full(drawable, desaturate_mode)I have no "Color>Color temperature" in my Gimp, it must be an add-on script/plugin? I can't answer without seeing it.

There is one by Luca de Alfaro: (under Filters/Colors/ convert color temperature
"script-fu-colortemp"

@Ofnuts, Dinasset
I think the OP is using the development Gimp 2.9.x
Both of those are GEGL functions.

Thanks for a respond guys.
I am using 2.9.6 GIMP
There is this option "Color to Gray" as it create 3D like structure out of picture. So just desaturation isn t enough for my case. It iseems it is part of GEGl operations integrated into menu.
What I don t understand - why isn t it possible to use GEGl functions in scripting - it makes it quite limitable.
temperature color - I didn t find function for input of stable values as I need it for batch processing.
Thanks

Tools>GEGL functions in Gimp allow people to experiment/debug with things that will be in 2.10. They aren't always fit for everyday consumption. In particular gegl-c2g is a performance hog. And it doesn't really create a 3D look, is mostly increases local contrast. You can use it to do a poor man's HDR: duplicate layer, do c2g on the bottom one, and set top (unchanged) layer to "color" mode.
2.9.x is work-in-progress, you can't complain that you cannot use the bathroom in a house that is still being built
This said, there are very many ways to do thing in Gimp, if you stated the original problem maybe we could come up with a solution that doesn't involve functionality that doesn't exist (yet).
