I want to remove black edge line whenever I generate svg files using stack(-s --stack_ option

Anyone know how to do that?

I'm passing the following command to convert a JPG to SVG but it's not generating any new file in the output directory:

python3 color_trace_multi.py --input="/content/logo.jpg" --output="/content/color-results" --colors=2

When providing an output path without quotes, the program does not recognize the argument. When quotes are provided when the output file is saved in the wrong directory, because the quotes are interpreted as part of the path.

I am not a python expert but this way it works just fine

Add this code to the main function ( def main(args=None): ) to line 883:

output_pattern =output_pattern.strip('\"\'')
inputs_outputs = zip(*get_inputs_outputs(args.input, output_pattern))

This will let the script work with long paths quoted.

After that the script can be called with quotes without problems e.g. :
python3 color_trace_multi.py -i "path1" -o "path2" -q as -c 32 -s

I'm trying to run the windows version, with this command line:
color_trace_multi -i png\*.png -o svg\* -c 0
But al i got is this error:
[Errno 2] No such file or directory: 'svg\\accept~tmp_scaled.png'
The path svg is created and accessible, so i can't figure out the error...

Can anybody help on this one?
Thanks

Hi, I would like to use this in windows. Wondering if there is a binary release or .exe already built?

When i submit a transparent background .png, the background results all black

Hi guys,

White color is getting automatically converted to transparent (removed)

Is it possible to preserve it?

Thank you

Regards,

Hi,
in my ubuntu os, i tried with
python3 /var/www/html/apps/color_trace/color_trace_multi.py -i /var/www/html/apps/color_trace/test.png -o /var/www/html/apps/color_trace/after.svg -c 8 but its gives error

Hi,
the only way I get any vectorizing done by this is script is using -c 0 option, if I change the value to anything else, I get just "Tracing complete!" but no output... Could you explain please?

Is there a way to omit the BG from the SVG?

Hello!

Could someone paste the command they're running in their terminal when working on a Windows machine? I haven't been able to get mine to run without errors and I can't tell if it's because I don't understand the formatting of the run command or if something is actually wrong. Thanks so much!

Hello;
the module threw "TypeError: can't pickle weakref objects" today at line 801 p.start()

As I have only very simple graphics (black + white + transparent), is it possible without greater rework, to remove the multiprocessing?
I took a look at your code today and it seems to be a big part of your code.

Here's a dump of the error trace

my code:
ctm.color_trace_multi(inputs=picpath,
outputs=outpath,
colors = 1,
processcount = 1)

error:
Traceback (most recent call last):

File "", line 4, in
processcount = 1)

File "C:\Users\Andreas\25 Heroquest\Questimator\Code\Multicolor_Symbols\color_trace_multi.py", line 801, in color_trace_multi

python3 color_trace_multi.py -v -i page.bmp -r remap.png -o out.svg

yields:
unsupported operand type(s) for *: 'int' and 'NoneType'.

EDIT
Hello,
i had some problems to use color_trace, the main problem was that i was using python in the terminal instead of python3 !

The correct syntax for me is:

linux@pop-os:~/Downloads/color_trace-master$ python3 color_trace_multi.py -i test.png -o test.svg  -c 8
Tracing complete!

Thank you for the project!

Best explained with a demonstration:

[stephan@host:~/src/color_trace]$ ./color_trace_multi.py 
/usr/bin/env: ‘python\r’: No such file or directory

\r characters are Evil.
