I am trying to change some text inside some figures of extension .EPS using the package psfrag. Unfortunately, one of the software which I am using to prepare these figures, the cad CATIA, has not an EPS output (only DXF, PDF, SVG, PS, PNG, JPG, TIFF, etc...). Then, I saved the figure as pdf and I converted the obtained file to EPS using Adobe Acrobat. But psfrag does not seem to work on this final file.
The other software that I am using, SigmaPlot, has an EPS output, however psfrag cannot operate neither on this output. It seems that there are different EPS formats, or codes maybe, and the ones that I get are not usable by psfrag. I have read a lot of posts on this argument thus excuse me please if this is yet another duplicate of things already explained. I have to confess however that I have not really understood the answers provided, probably because I am a beginner on Latex.
Then, I would like to ask: are there different EPS formats? How can I get the one usable by psfrag? From which file is better to pass, I mean it is better to generate first a PDF and then convert this in EPS, or maybe it is better to have firstly a JPG? How can I obtain the EPS from the firstly-generated file? Or in alternative, what is the best way to handle this problem in Latex. Many thanks in advance
