C:\Program Files\LyX\Resources\lyx\configure is used to populate
lyxrc.defaults in the same directory. (It also generates a few other files,
but let's keep things simple for now.)
Here's what configure generated for me on my Linux box for all things
PDF-related:
============================================
\Format pdf pdf PDF P
\Format pdf2 pdf "PDF (pdflatex)" F
\Format pdf3 pdf "PDF (dvipdfm)" m
\converter latex pdf2 "pdflatex $$i" "latex"
\converter dvi pdf3 "dvipdfm $$i" ""
\converter ps pdf "ps2pdf13 $$i" ""
\converter eps pdf "epstopdf --outfile=$$o $$i" ""
\viewer pdf "acroread"
\viewer pdf2 "acroread"
\viewer pdf3 "acroread"
============================================
It could do that because it found pdflatex, dvipdfm, ps2pdf13, epstopdf and
acroread in the PATH. On Windows, however, such things may or may not be
found in the PATH. Things like AcroRd32.exe and ImageMagick.exe can be found
in the registry. For example, the location of ImageMagic.exe can be found by
calling RegGetValue:
RegGetValue(HKEY_LOCAL_MACHINE, "Software\ImageMagick\Current",
"BinPath", ...)
and will fill a variable with something like:
C:\Program Files\ImageMagick-6.2.3-Q16\convert.exe
I'm suggesting that we should use the "C:\Program Files\ImageMagick-6.2.3-Q16"
part to augment the PATH that is used by LyX by augmenting the path_prefix
variable that is/can be stored in lyxrc.defaults.
Make sense now?
