PLOS journals require submission of EPS format figures instead of PDF. Most of my figures were made in PDF and I used to simply crop the excess margins and use pdflatex to process the final output.
Now I am forced to use latex instead of pdflatex and had to convert my figures from PDF to EPS. What is the best way of achieving this? Can I crop the margins after EPS is created? Alternatively can I crop the margins in PDF then convert it to EPS? Which one will produce a lossless result?
