Apparently, pdflatex incorporates more font information than is required in PDF
documents.
This seems to account for what -- in my opinion -- is unacceptable, 3-fold
bloat in the size of PDFs. As one example, one of the letters that I generated
with GNUmed and which was barely over a page long ended up at 230K which is
huge, compared to the fact that *scanned* paper (or e-faxes) are only about
70-100K per page.
Apparently the open source ghostscript (or Adobe's products) will achieve much
smaller PDFs. The best posting that I could find on this makes reference, in
one of the comments, to
a python-script called pdfsizeopt.py, code.google.com/p/pdfsizeopt
which reduces the size of pdfs. I use it frequently, but with texlive
2010 you
need to begin your *.tex-file with\pdfminorversion4
and the same thread, in the bottom 'answers', references a whitepaper that came
to the same conclusion of recommending the above python script, and the
'answer' concludes with:
The final recommended workflow for small PDFs is:
1. use pdftex;
2. process with pdf enhancer or acrobat pro if you have them;
3. process with pdfsizeopt (including the optional multivalent step).
here is the thread
http://tex.stackexchange.com/questions/19956/which-one-produces-a-pdf-with-the-smaller-file-size-pdflatex-or-latex-dvips-ps2
from which came the links
http://code.google.com/p/pdfsizeopt/
http://code.google.com/p/pdfsizeopt/downloads/detail?name=pts_pdfsizeopt2009.psom.pdf
Less optimal but perhaps easier (?) could be to use one of the other approaches
referenced above, namely to use ps2pdf (a wrapper script which uses ghostscript)
http://www.tug.org/pipermail/pdftex/2004-June/005046.html
which is similar advice to
latex + dvips + ps2pdf reduces the file size by almost 3 times
http://7fttallrussian.blogspot.com/2011/02/latex-reduce-pdf-file-size-with-latex.html
and
"DO use dvips to create PostScript file"
"Use Acrobat Distiller (or ghostscript) to convert PostScript to PDF
http://slantchev.ucsd.edu/edu/latex/latex-pdf.html
Feasible to adopt? Otherwise every 4 pages of *text* generated by GNUmed will
cost one Mb or thereabouts, and that is just too much (IMO).
