Subject: [R-pkg-devel] Resize PDF Vignettes in Source Package

--compact-vignettes alone did not work.
--compact-vignettes=gs+qpdf did the job.
Thanks.

Dear all,
I want to add PDF vignettes to my package created with rmarkdown. The PDFs are generated without problems. If I submit the package to CRAN I would a warning telling me that the files are too large (see below):
checking sizes of PDF files under 'inst/doc' ... WARNING
'gs+qpdf' made some significant size reductions:
compacted 'Manual.pdf' from 370Kb to 116Kb
consider running tools::compactPDF(gs_quality = "ebook") on these files
I do run `tools::compactPDF(gs_quality = "ebook?)` and the size of the PDF is indeed reduced to 116Kb. Now, if I build again the source package using `R CMD build <package_name>` the vignette is reconstructed at its original size (370Kb). However, If I build the package using `R CMD build <package_name> --no-build-vignettes` in order to keep the small PDF, the check would throw me the following NOTE:
Package has a VignetteBuilder field but no prebuilt vignette index.
Any ideas how can I include the compacted PDFs in the souce package and have a vignette index in the same time?
When you build the tarball, use the --compact-vignettes option.
