Question

How can I convert multiple .jpg files to .eps files on Linux?

Answer 1

When using the ImageMagick's convert, it is a good practice to use the eps2 format. This make the resulting eps file much smaller because it uses the JPEG compression algorithm (DCT).

So, to convert a.jpg to a.eps do:

convert a.jpg eps2:a.eps

This of course, can be used in a shell script, to convert multiple JPG to EPS.

I get the following errors when I execute : convert: unable to open image pic.jpg': ��. @ error/blob.c/OpenBlob/2489.` convert: unable to open image pic.jpg': @ error/blob.c/OpenBlob/2489.` convert: missing an image filename eps2:pic.eps' @ error/convert.c/ConvertImageCommand/2940.` What should I do? – Sufferable

Use imagemagick mogrify command instead of convert for multiple files. mogrify -format eps3 *.png – Osculum

Answer 2

You can use many tools. I recommend using convert command from ImageMagick.

#!/bin/bash

# example 1
convert myfile.jpg myfile.eps

# example 2
for file in file1.jpg file2.jpg file3.jpg; do
    echo convert "$file" $(echo "$file" | sed 's/\.jpg$/\.eps/')
done

To make example 2 run you need to remove the echo inside the for-loop. Make sure the commands it outputs are correct before removing it.

Answer 3

According to user1958943, I used the convert tool as well. However, as the eps3 format gives an even better compression with similar quality as eps2, I suggest to use

convert a.jpg eps3:a.eps

By the way, this tool also works for png files (and also others) ...

Does anybody know which compression eps3 is using?

what is the difference between eps2 and eps3? – Tyrannize

Version 3 is specified in appendix H of the following document: www-cdf.fnal.gov/offline/PostScript/PLRM2.pdf. The changes to version 2 are listed in section H.8. However, I am not sure whether you find the details about compression there... – Hailee

Answer 4

Another option is to combine jpegtopnm and pnmtops from the netpbm toolkit. This will however produce PS, not EPS.

for f in *.jpg
do
  g=`echo "$f" | sed 's/\.jpg$/\.eps/'`
  echo "$f -> $g" 1>&2
  jpegtopnm $f | pnmtops > $g
done

This produces a PNG file, not an EPS. You probably want to use pnmtops instead of pnmtopng. – Kawai

Answer 5

ImageMagick's convert can do that for you.

Answer 6

I do this often and sometimes on Windows. Hence, I wrote a small online converter which uses convert:

JPG to EPS Converter.

Hope this can also help others.
