I've had problems with "pencil portrait" on G'MIC. Works, but takes forever. Is it possible to make a stand alone script/plugin for this feature? I wondered if it would take as long if separate? Thanks.

Have you tried Rod's or Dinasset's Pencil Portrait scripts?

Huh uh. I was wanting the same Pencil Portrait as on G'MIC. Love that feature.

I don't think G'MIC is slow because it has many filters, since when you select a filter it goes into that piece of code it's not running other things at the same time.
I wouldn't know how to reproduce the effect in G'MIC in GIMP.
Unless you knew the steps to reproduce it in GIMP then i could script it but i doubt it'll be faster, probably even slower (as i think G'MIC is already compiled code).

I wondered if it wouldn't be slower. Funny that it's the only feature on G'MIC that does that.Everything else works fine. I uninstalled it, and reinstalled it, to no avail. It used to work fine, then all of a sudden didn't anymore. I don't know if it was from something different in G'MIC itself, or something wrong with my PC.

It seems others have the same problem with it: viewtopic.php?f=28&t=13648

Try to follow the original tut

I created script that does what this tutorial described.
It's slow on large images, so i only tested with image of 400pixel width.

by the way it was really easy too that you posted the gmic command used for the plugin...but how did you get that command string? is there an output of that somewhere when you run any gmic filter?

"...but how did you get that command string? is there an output of that somewhere when you run any gmic filter?"
third entry in Input/output, use "Verbose (layer name)", you'll get the command string used

Thanks jamac4k.

Thanks tin, but after 5 minutes, I gave up.

Problem is Ink Wash usually is so slow.

I just doing the tut changing Ink Wash by Freaky B&W (default values):

Very nice jamac4k. Thanks again, appreciate it. Perhaps tin can alter the plugin.

It's not Inkwash it's slow but it is not that slow.
It's the Sketch layer that takes the longest for me.

It seems odd to me. Sketch by itself doesn't take much time at all.
