Sorry to derail -- but this piqued my interest in c2g -- where can one find it in recent GIMPs? It's not in the Tools->GEGL menu... (I'm on otto-kesselgulasch-gimp-edge PPA).

Thanks, -c

Hello folks!

Is there some way how to run Tools/GEGL/C2G convertion in command line like batch?

For example - I have 10 pictures which I want to convert with some params. This conversion takes a lot of time when you have to load picture into Gimp, set C2G params and convert. I would like to convert it trough night like batch

Thx for your advice in advance.

In gimp 2.9.5 the menu entry is

colors -> desaturate -> color to gray

For incorporating in a batch operation? AFAIK since c2g does not show in the procedure browser, it might not be possible.

rich: www.gimp-forum.net

It's under Colors -> Desaturate -> Color to Gray

If I am not mistaken, you need to put everything in an XML file as gegl from command line needs an XML file to operate on. Put everything in an XML file and then do the following:
gegl file.xml -o output.png.

Once you do that I am sure you can figure out how to do that for 10 images.

Anyway, that's my understanding. Others may be more helpful to you.

In recent GEGL releases there is an underdocumented commandline one-liner shorthand to avoid creating XML documents:

For instance:

gegl input.jpg -o output.png -- c2g radius=1300 samples=4 iterations=23 vignette

will apply the c2g operation with the following paramteres, followed by the vignette filter with default parameters. To make this apply to multiple images one could for instance do:

mkdir /tmp/out ; for a in *.jpg; do echo $a; gegl $a -o /tmp/out/$a.png -- gegl:c2g radius=1300 samples=4 iterations=90 ; done

GEGL will complain if you specify properties not valid for a given operation and print the exisiting properties that can be assigned. If the gegl: prefix is avoided on an operation gegl tries with gegl: pre-pended.

I don't know what to tell you. :(

I loaded your original image in McGimp (my Mac GIMP build) and then used the gegl command line with same parameters: rad = 300, samples = 4, iter = 10 and I got identical results.

$ date; gegl res_WLDF1130.jpg -o res_WLDF1130-GEGL-CLI.jpg -- c2g

radius=300 samples=4 iterations=10; date Sat Feb 11 22:59:19 EST 2017

I tried it again and have to say I overlooked this message. I got the same error(?) message. :/

What error message is that?
