2) Set the paper size to 200" x 200"
AFAIU now, the issue is that the PDF output is compressed, not the PostScript
output of ps.map, which should be a best resolution. The
above trick is to get a create a resolution PDF, at the expense of
incorrect paper size. ie fool acrobat reader.
I have struggled with the same issue -- PDF conversion with the
ps2pdf13 gs wrapper reduces the images to 72dpi.
for the PS -> PDF conversion try:
gs -q -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -dPDFSETTINGS=/printer \
-sOutputFile=out.pdf in.ps
I tried with "-r1200" and "-r600x600" and "-density600" gs options but
those had no discernible effect AFAICT*, although the file sizes changed
a small amount (got smaller!). Probably due to the fact that I don't
know ghostscript very well.
"-dPDFSETTINGS=/printer" seemed to do the trick though.
Normally, you should actually be able to give this option directly to
ps2pdf:
