Results of my "photo to cartoon" plugin

mahvin · **Joined:** Oct 06, 2010 **Posts:** 4050

I must say, after spending the whole day reading, dabbling, and tweaking with FINK, Homebrew, CMake, and shell scripts, MacPort came to the rescue on this 2013 iMac. My goal was to get this (bede2.10.py) up and running on a MacOS just so I could see how the bede plugin worked. Great, btw! I tossed in a bit of Hillustrative to enhance, (both plugins rely on G'MIC) and I just can't get enough of this cartoon effect. I'm flabbergasted at how well it works!

Hello,

On some photos, I like when an emboss effect is applied after the "cartoon" effect.

Here is an example:

Enjoy!

Cli345,
This effect looks really cool.

Thank you Nidhogg!
The merits are all of Cli345, which created the technique, the plugin and shared them with us, in addition to doing the same with the steps for the emboss associated with this plugin.

Many beautiful results displayed here on this thread, that of Mahvin (above) is a work of art!

Krikor, I like your creation a lot. It's great!

Nidhogg · **Posted:** Thu May 27, 2021 9:08 am **(#66)**

Tried the emboss effect, saved all steps to presets. Bede rocks!

This is probably a temporary bug with the number of parameters in the G'MIC for fx_curves_interactive - because running it gives an error.

Look here:

I tested the modified version and no problem.

Hello,

Thanks, rich2005, mahvin, Krikor, Nidhogg, Issabella, level_0, MareroQ for your very valuable feedbacks! :tyspin

(particularly to MareroQ for the fix).

Hello!

Here is a similar filter (photo to cartoon). It's not exactly the same effect.

Attachment:

apples_k7252-65_compGegl.jpg [ 389.26 KiB | Viewed 11604 times ]

It's not better but it's made entirely with "GEGL graph".

Enjoy!

cli345 · **Posted:** Sun Jul 25, 2021 9:21 am **(#73)**

Hello!

It's just the "photo to cartoon" plugin ("Comic Book for 2.10") with an additional option: "Simplify".

If the "Simplify" option is 0, the plugin acts almost exactly according to the old behavior. If it's 1, a slight simplification is applied. For 2, a stronger one is applied.

On my PC, with this file, this G'MIC version was faster than the "Comic Book for 2.10" filter.

In Windows it is "%APPDATA%\user.gmic"

Now that gmic_gimp_qt stable is now 2.9.8 you might want to look at the changes in the syntax again. As commented on pixlus.
I have been using 2.9.8 for some time now so my bede_cartoon.py script already modified.

Code: Select all

    #pdb.plug_in_gmic_qt(img, layer, 1, 0, '-fx_curves_interactive 7,0,1,7,0,0,'+pointLum+',100,100,-1,0,0,'+pointSat+',100,100,-1,0,0,100,100,-1,0,0,100,100,-1,')
    pdb.plug_in_gmic_qt(img, layer, 1, 0, 'fx_curves_interactive 7,0,1,"7","0,0,'+pointLum+',100,100,-1,0,0,'+pointSat+',100,100,-1,0,0,100,100,-1,0,0,100,100,-1"')

The .gmic file, well I got that going with some nested quotes

Code: Select all

+fx_curves_interactive.  7,0,1,"7","0,0,{'50-$augmLum'},{'50+$augmLum'},100,100,-1,0,0,{'50-$augmSat'},{'50+$augmSat'},100,100,-1,0,0,100,100,-1,0,0,100,100,-1"

....but the simplify variable can throw up an out of range error

beyond my pay-grade.

Indeed, I haven't seen that G'MIC stable version has become "2.9.8" for 11 days!

The .gmic code is quick and gives a really good result.
The frequent updating of the gmic syntax is understandable - gmic is work-in-progress but frequently results in filters breaking.

(Using a 2.10.22 appimage and a gmic_gimp_qt 2.9.8 plugin that I compile for it.)
