Hmm, just to make sure I understand you correctly: psfrag works well with text labels which are inserted by inkscape, but any labels already existing in the original EPS file are inevitably destroyed?? I hope that's not right, as in this case I'd have to look for an entirely different solution.

I've studied the problem a bit more...

Yes, psfrag works with text labels inserted by Inskcape. And yes, importing EPS into Inkscape may convert the text labels to paths... losing their ability to be used as tags for psfrag. This depends on which version of Inkscape you are using and where you got it from.

The current SVN version uses the program "pstoedit" to convert EPS into svg. The exact command is `pstoedit -f plot-svg`. This command does not convert the text to paths (although the SVG file it produces looks a bit strange).

To use the SVN version, replace the contents of: share/inkscape/extensions/eps_input.inx with

<inkscape-extension> <_name>EPS Input</_name> <id>org.inkscape.input.eps</id> <dependency type="executable">pstoedit</dependency> <input> <extension>.eps</extension> <mimetype>image/x-encapsulated-postscript</mimetype> <_filetypename>Encapsulated Postscript (*.eps)</_filetypename> <_filetypetooltip>Encapsulated Postscript</_filetypetooltip> <output_extension>org.inkscape.output.eps</output_extension> </input> <script> <command reldir="path">pstoedit -f plot-svg</command> </script> </inkscape-extension>

You must have "pstoedit" available with plot-svg from the GNU libplot library.

Another way to get a decent svg file for input into Inkscape is to use the chain:

pstoedit -f sk test_original.eps test_original.sk skconvert test_original.sk test_sk.svg

This seems to produce a bit better svg, again with the text not converted to paths.

...

You could replace the text as paths with text as text.

Uhm, what do you mean by this?

That you could manually replace the text (paths) imported by Inkscape by text objects (real text). Obviously one of the above methods would be better.

Hello,

some new experiences related to the issue of inkscape's text import and export in EPS format! :-)

To use the SVN version, replace the contents of: share/inkscape/extensions/eps_input.inx with

Soo... after I changed that file, the psfrag part worked again, but the BBox is messed up. If I copy the BBox line directly from the original EPS file to the new one, everything is fine! The size of the resulting image is still slightly different than before the im/export, but I guess I can live with that. It might be adjustable by fiddling with pstoedit. I have to check that, or sed otherwise. Ah, and also the psfrag labels are displayed in inkscape at 10% of the real size (i.e., dots), but that might be a local problem with that font (Helvetica), as marking the label and changing it to something else gives a correct size. The resulting EPS has the correct psfrag label fontsize again, anyway. :-)

However, by now I'm kinda thinking I am going to program the labeling that I wanted to do manually into octave/gnuplot. I don't know what other disasters to expect with this whole conversion stuff...

pstoedit -f sk test_original.eps test_original.sk skconvert test_original.sk test_sk.svg This seems to produce a bit better svg, again with the text not converted to paths.

Yes, that also worked, except that the labels of the x-axis were slighty moved upwards, into the x-axis. :-( Therefore, not an option. (BBox was also wrong.)

Yes. :-)

Thanks a lot for your help! Greetings, David
