GEGL Gradient Map

[Konstantin]

I just watched a video on youtube which uses a GEGL gradient map.

However this filter is not in my Gimp 2.10.18 "Tools - GEGL Operation" list. In fact i have only 12 filters in my list.

I don't have it either.
Win 10 Samj's pack Gimp 2.10.19

[ofnuts]

It's there in 2.10.14 but in my 2.10.19 it disappeared (like 9 other GEGL filters...);

will i miss anything crucial if i go back to 2.10.14 ?

Same as Ofnuts:
I only know of one specific version which has the long listing. A linux Gimp 2.10.14 from the ubuntu otto-kesselgulasch PPA Everything else I have come across has the shorter listing. It was mentioned by the developers two years ago, seems to have been dropped, not in the listing of GEGL operations http://gegl.org/operations/

If you are running ubuntu 18.04 or Mint 19 It should still install. That is what I use in kubuntu 18.04 + a Gimp 2.10.18 appimage. They co-exist.

I don't think anyone has posted this but if you don't want the long list and only search for the function (Gradient Map), there is Colors > Map > Gradient Map. It's not exactly the same, but it works for me. You just need to edit the Brush/Pattern/Gradient area of the Toolbox.

Indeed it works well, but with almost no control (chose the gradient) nor visual adjustment

On the other hand, Filters > G'MIC > Black & White > Colorize [with Colormap], is even better (IMHO) than the GEGL Gradient map and it has also more options

I will see if I can rescue these filters.

I failed to build it (unless I rebuild GEGL). If someone gets it alone then hooray.

[rich2005]

For a linux binary, you can get a libgegl-0.4 debian package from here: https://launchpad.net/~otto-kesselgulas ... /+packages

Unpack the deb for possible binary plugins. Example:

can you link the file exactly, I can't find it.

[rich2005]

Comes from this package https://launchpad.net/~otto-kesselgulas ... _amd64.deb (edit-this the 20.04 packge)

and from there gradient-map.so attached

Thank you I got it. I am also tinkering with the GEGL transparency inpaint operation as an alt to resynth and GMIC's inpaint.

I wonder of paint select's raw GEGL operation will compile on 2.10? Not the new brush in Gimp 3 but the raw GEGL Operation behind it.

HSL color goes good with Gradient map

The case is a little different.
Lost Gegl Operations are available in GEGL code.
It is up to the compiler whether to include them - they are turned off by default as experimental (workshop = false).

Workshop contains (list of gegl-0.4.16):

aces-rrt.dll
bayer-matrix.dll
bilateral-filter-fast.dll
connected-components.dll
demosaic-bimedian.dll
demosaic-simple.dll
ditto.dll
domain-transform.dll
enlarge.dll
gcr.dll
gradient-map.dll
hstack.dll
inpaint.dll
integral-image.dll
linear-sinusoid.dll
rawbayer-load.dll
segment-kmeans.dll
selective-hue-saturation.dll
voronoi-diagram.dll

external:
gluas.dll
line-profile.dll
spyrograph.dll

generated:
average.dll
blend-reflect.dll
negation.dll
soft-burn.dll
soft-dodge.dll
subtractive.dll

I do not know if anyone is interested in it, but apart from the information provided, I would like to add that currently (Gegl-0.4.35 in Windows) creates one file gegl-workshop.dll out of 17 source files:
aces-rrt.c
alpha-inpaint.c
band-tune.c
bilateral-filter-fast.c
boxblur.c
boxblur-1d.c
connected-components.c
demosaic-bimedian.c
demosaic-simple.c
ditto.c
gcr.c
gradient-map.c
integral-image.c
rawbayer-load.c
segment-kmeans.c
selective-hue-saturation.c

The Vignette GEGL Operation was more powerful than the one you can use in GEGL Graph. I did not see that on the list at all.

This is a picture of me and my granddaughter I took with my cellphone, and then after running it through GMIC and using the gradient map.

[MareroQ]

Was this gegl filter different?
