I have some PDFs that have embedded fonts, which won't display in Preview in OS X (as far as I know, due to a bug in Preview).
To fix this, I ran the PDF through
pdf2ps and then back through
ps2pdf, which fixed things in Preview, while still leaving the text intact (i.e. selectable). Adobe Reader shows the same embedded fonts as before in document properties (only this time it's a subset of the font).
However, one of my PDF has elements with opacities, which PostScript can't handle (it just rasterises the whole thing).
My question: Can I achieve the same effect (with regards to the fonts) as
ps2pdf but without converting to PostScript? Or just in a way that doesn't break when opacities are involved?
