# Some TeX Developments

Coding in the TeX world

## EPS graphics with PDF(La)TeX

One issue a lot of people find confusing with (La)TeX is the rules about which types of graphic files work with which engines. EPS files are fine when going via the DVI route, but do not work with direct PDF creation. The solution is to turn the EPS files in PDFs, and the problem goes away. However, there is then the question of how to do the conversion.

For most documents, having to convert every file by hand is not a sensible choice. The next nearest thing is the epstopdf package, which will do the same thing but from within a LaTeX run. However, it needs `\write18` enabled, and this is not always desirable. More importantly, a lot of people who struggle with the graphics problem do not know how to turn on `\write18 `anyway. A good way around has been added to the latest version of TeX Live, which is currently in the final testing stages. TeX Live 2009 has some restricted `\write18` functions enabled as standard, and also has a version of epstopdf “built in”. The result is that EPS files are automatically converted to PDF files, in a transparent manner. Of course, this only happens if the PDF does not also exist! At the moment, this feature is not in MiKTeX 2.8, so it is one reason to favour TeX Live 2009 even on Windows.

There are places where epstopdf will not help: for example, when using psfrag or pstricks. There, the best solution will either be auto-pst-pdf or pstool. Both are written by Will Robertson, and both need `\write18` enabled to work. pstool is more efficient (it only re-creates graphics as needed), but for some cases on auto-pst-pdt will work. Will has documented both packages very well, so the best way to learn about them is to have a read of the documentation.

1. Cool. Will upgrade to Texlive 2009 once it’s released!

2. The binaries for TeX Live 2009 are pretty stable. According to Karl Berry, all that is left to really do is translations. Expect a release in a few days, I think.

3. According to the MiKTeX 2.8 release notes it has also \wite18 partially enabled.

4. Yes, but currently MiKTeX doesn’t have the “auto-epstopdf” idea that TeX Live does. It’s a good idea for helping new users, so I’d imagine it will in time appear in MiKTeX as well.
