The reason why I post stuff like this here is twofold. Firstly (is that even a word?), I forget. Chances are that in 3 months I will need this shit again, and won’t remember the exact syntax, or the name of the tool I used. So instead of googling for it, I can just search through my blog archives.
Secondly, chances are that there are quite a few intermediate or beginner latex users out there who may or may not find this useful.
Here is the scenario: you created a beautiful Latex document. In fact it is so awesome that someone approaches you and asks you to send them that incredibly cool chart or figure you used in your paper. So you send the person the eps/ps file and they can’t open it.
The proper raction that should be taken in such situation is of course repeatedly whacking said person on the head with a blunt object until they get a clue. Sadly forcible clue insertion is not always an option, so every once in a while you will need to convert your images into some more luser friendly format.
You can convert any ps or eps file into a jpeg using ghostscript:
gs -sDEVICE=jpeg -dJPEGQ=100 -dNOPAUSE -dBATCH -dSAFER -r300 -sOutputFile=myfile.jpg myfile.eps
This method has one flaw. It produces humongous files. Depending on the eps file you may get something like 2000×3000 pixels which is slightly on the insane side. Also the file size of the JPG will be about 10 times that of the eps.
We will now need to trim and resize the file using some Image Magic tools:
mogrify -trim -resize 800x600 myfile.jpg
Obviously you can put your own dimension instead of the 800×600. Mogrify will resize the image, and also cut down the size of the file to a manageable level. Still, in most cases files obtained using this method were bigger than the eps files used to produce them. It’s best to simply use your photo editing tool (gimp?) and re-export the image/chart to a conventional image format. It will probably yield much better results than this conversion.
On the other hand, if a ps/eps is all you have, this might be useful.
