I'm writing a TeX document in which graphics are converted from .eps to .pdf using epstopdf.
For the most part, everything works fine, but for two of the figures, the pdf that is generated from the eps file (i.e. figure-eps-converted-to.pdf) is completely blank.
The result is a normal document but with a blank image in place of these two graphics.
EDIT: The figures were both created in MatLab, before subsequent editing in Adobe Illustrator.
Does anyone know of an element of the package epstopdf that would stop it from properly converting my .eps file? The TeX code to include these graphics is exactly the same as for the those that work fine.
