I'm currently working on a LaTeX document with some photos in it. As I'm using the PowerDot class, which is incompatible with pdflatex, I need to convert all my images to EPS and use ps2pdf to get my final PDF document. On the first attempt, I used the command
ps2pdf file.ps file.pdf
and it worked, except that my photos came out all muddy, a result of over compression. So, I added the option to turn off compression,
ps2pdf -dEncodeColorImages=false file.ps file.pdf
and end up with the wonderfully obtuse error message
Error: /undefinedfilename in (false)

Ick.
It turns out that ps2pdf on Windows is a batch file, and batch files do not accept = in an argument. I had no idea that this was the case, but so it is. The solution, which is annoyingly absent in the documentation, is to replace = with #. Thus, the command on windows should be,
ps2pdf -dEncodeColorImages#false file.ps file.pdf
Like that, it works. And, I get my beautiful uncompressed photos in my document.
