Good stuff. A few more optimizations and maybe, just maybe, I might be able to pull one off myself.
Thought it was a butterfly until I scrolled up (No; didn’t take any drugs. lol)

Does your version match the latest (2.67 or 2.7)? Might be an older version…

How does one go about doing this by command line? and to use own images as style?
I am trying to start to use pyton-gmic 
The example I was given is
gmic.run(“pathtoimage _fx_stylize starrynight +fx_stylize 1,6,0,0,0.5,2,3,0.5,0.1,3,3,0,0.7,1,0,1,0,5,5,7,1,30,1,2,1.85,0”)
But it says it can’t find the image. And if I try to put the path in my own disk it still tries to download it from the server.
I write this message also for the future if someone wants to do the same
try with
… output out.png")
It has nothing to do with the output.
The problem is it’s not reaching the image for the style.
GmicException Traceback (most recent call last)
in
----> 1 gmic.run(“athoimage _fx_stylize starrynight +fx_stylize 1,6,0,0,0.5,2,3,0.5,0.1,3,3,0,0.7,1,0,1,0,5,5,7,1,30,1,2,1.85,0 output out.png”)
GmicException: *** Error in ./_fx_stylize/*if/ *** Unreachable network file ‘https://gmic.eu/img/style_starrynight.png’.
But the file exists.
and if I try my own image it still tries to search in the server so I need to know if the command is different for a local style or if it’s not possible with a local style

The command string you are showing calls:
_fx_stylize starrynight
this commando looks in ${-path_cache} for the file starrynight.png . If it is not located there gmic tries to download it. Seemingly you have a net problem. try “e ${-path_cache}” to see where it is located.
With your own style image try something like
“sourceimage styleimage +fx_stylize 1,6,0,0,0.5,2,3,0.5,0.1,3,3,0,0.7,1,0,1,0,5,5,7,1,30,1,2,1.85,0”
or
“sourceimage styleimage rv +fx_stylize 1,6,0,0,0.5,2,3,0.5,0.1,3,3,0,0.7,1,0,1,0,5,5,7,1,30,1,2,1.85,0”
sourceimage and styleimage should be filenames of images in gmic. I don’t know how images are addressed in python-gmic. rv exchanges the two images in the list if necessary, I don’t know the sequence for stylize of the images! At least you have to load two images and than call fx_stylize!

yay gmic-py in the place!! It seems your computer’s or network’s proxy settings block access to gmic.eu… does running the same command in the gmic cli executable work? gmic-py and gmic cli both use libcurl for accessing internet files… but maybe I should improve the python module’s self-configuration…
Just tested now with Wifi at home:

I guess you can see
libcurl_enabled:1
in your gmic.__build__ output
if yes, then you may have something blocking outgoing http/https calls on your computer or network

Thanks! This worked. I am now on a quest to understand the parameters. It works beautifully! I just want to tweak things here and there.

gmic-py has exactly the same syntax as the g’mic language, except that to follow also closely the C++ API, a gmic_list of images is updated along your command string, with the buffers in order. In gmic-py this gmic_list has no special type, it is just a list of GmicImage object.
This images list thing is shown here in the doc’s Quickstart chapter: Quickstart — gmic-py 2.9.4-alpha1 documentation
But writing to you makes me realize there is not even one example on gmic-py’s Github dealing with images list for beginners…
so in short
you may be used to doing this in command line
gmic "my command"
G’MIC commands work in sort of polish notation like:
<buffers aka images from scratch or from previous command> some_command com,mand,scal,ar,para,meters
gmic-py imitates the very little known c++ api where the gmic interpreter takes actuall 2 parameters: a string, optionally: images to use and edit in place:
import gmic
images = []
gmic.run("sp apples sp earth blur 4", images)
#and images are in-memory images to reuse in a gmic.run
gmic.run("sharpen 3", images)
