Input: pdf file with vector graphics
Output: eps for LaTeX with some text and graphic annotations overlayed
Requirements: The goal is to preserve the best quality graphics possible. In particular, we want to preserve the vector graphics, so Photoshop and GIMP, which are raster-based programs, are not suitable.
This is really much harder than I expected.
When exporting to eps, you want
Convert pdf file to eps
pdftoeps -eps input.pdf
Note that pdf2ps and pdftoeps are not the same.
Open resultant input.eps file in Open Office Draw.
Perform crops, rotations, resizing.
Add text and graphic annotations
Now it's time to export.
First try to export directly as an eps. Open the eps file in okular. If everything looks good, then you should be done.
Note about viewers:
All viewers are not really equally good for checking eps files.
Gwenview appears to rasterize. You can use it for determining gross contents of files, but don't use it to determine image quality.
Okular should
I end up with a blank file.
Work around:
Export Open Office file to pdf. (intermediate.pdf)
Export only one page
lossless compression
pdf2ps intermediate.pdf
ps2epsi intermediate.pdf final.eps
