No i don't want upload yet another cartoon filter, also because i am not really happy with it

Not that is so bad but...oh well if you want try it

Has the same controls of BW/Charcoal (and as charcoal is a bit tricky, the positive/negative shift is hard to control )

Add the posterized color of the original to the outlines and black filling from Charcoal

Where will I find this filter. I placed the code in my Roaming/gmic file refreshed filters and restarted gimp but no changes "the Flying Cartoonist" has flown away.

Sorry a copy and paste error

now fixed, delete that snippet please and replace with the correct
It should appear on top under the faves

Do I have my gmic and gmic_faves files back to front I placed your ammended code in my gmic file not gmic_faves file and there she blows And it does not like transparencies.

Ah transparency and multiple I/O
This should fix both..sorry replace again

i slightly change function name so should be not conflict with the order code
the difference is that instead then use -index that require a colormap use -quantize , hopefully colors will be more close to the posterized original color

This version is no good as it did not show in gmic menu? Sorry had to leave last night to go out for tea at the club

My fault a "#" at the very start went lost..now is fixed

yes now should work

Ok another one as now is called Color Stamp to not confuse but will be Flying Cartoonist
The other based on Charcoali want to simplify (removing chalk highlight and boost contrast options that i do not like and make the gui too confusing

ok COLOR STAMP

actually are 5 recolored gmic filters all here viewtopic.php?f=9&t=3311

Maybe i will put soon in my filter source as now they all work but ...well i didn't find yet how to remove unwanted options from charcoal and quantize has not the posterize effect i wish

but well i like play with a idea (and a hope David to pop out with a new .autoindex command)

That is cool!

That is cool Griatch, It put shadows where there weren't any.

that may be increased or decreased unchecking the first option (the "automatic" ) and setting manually the first slider

the first slider is inactive if "automatic" is enabled

some more example this is Colored Sketch seems perfect to simulate a quick draft



or with less intense sketch lines(i lowered the sketch opacity...from the filter is one of the sliders)



This is Colored Pencil...maybe too similar to Graphic Novel even if use another approach

You are just a wizard with this stuff, all looks so cool!
