Question autotrace batch processing


I have been using

autotrace input.png --output-file output.svg
to convert single .png to .svg

how do I convert more than one file at the time? I have 200 .png in one folder that I want to convert to .svg.

Should be quite easy:

for i in *.png; do
autotrace "$i" --output-file "$(echo $i | sed 's/.png/.svg/')"
That will take all the files in the current directory (e.g. 1.png, foo.png, bah.png) and convert them to .svg (writing them to 1.svg, foo.svg and bah.svg respectively)

Hope this helps,

thank you Snark1994!

It worked fine.

I am new to the command line, but I shall get into it more when I have some time.

I am using it as an "effect" on a video, like this:

ffmpeg -i fro.avi image%d.png
for i in *.png; do autotrace "$i" -despeckle-level 14 --output-file "$(echo $i | sed 's/.png/.svg/')"; done
for i in *; do rsvg-convert $i -o `echo $i | sed -e 's/svg$/png/'`; done
ffmpeg -i image%d.png -vcodec huffyuv test.avi
and it gives a really nice cartoonie look to the video, when I know more about what I am doing, I shall put togheter a script of it, so that it deletes all svgs and pngs in the end.

Thanks again!
