Unfortunately, this seems to be very dependent on versions of software
in use, including LaTeX and Ghostscript (and fonts?). I can compress
your pre-built 372Kb vignette to 96Kb (as does the CRAN machine), but
when I rebuild the package, I can only get down from 276Kb to 156Kb:
R -q -s -e '
untar("microplot_1.0-47.tar.gz.orig");
tools::compactPDF(
"microplot/inst/doc",
gs_cmd = "gs", gs_quality = "ebook",
verbose = TRUE
)
'
qs_quality="ebook" : use_gs=TRUE, use_qpdf=TRUE
#{pdf}s = length(paths) = 1
- microplot/inst/doc/rmhPoster.pdf: gs: res=0; + qpdf: res=0;
==> (new=98115)/(old=380862) = 0.257613 =====> using it !!
compacted ‘rmhPoster.pdf’ from 372Kb to 96Kb
LANGUAGE=en R_GSCMD=gs GS_QUALITY=ebook R CMD build \
--compact-vignettes=both microplot
<...>
* creating vignettes ... OK
<...>
* compacting vignettes and other PDF files
compacted ‘rmhPoster.pdf’ from 276Kb to 156Kb
And 'gs --version' says '10.00.0', which shouldn't be that different
from your '10.03.0'!
