Hey All,
Another question, why is it that the qvm-convert-pdf function returns a
file that is slgihtly fuzzy?
I keep lots of copies of important documents that I want to convert to
secure pdfs since they don't need to have anything other than an image.
However, I need them to be as clear as possible so I can print them back
out as if they were the original.
Using qvm-convert-pdf currently makes a really fuzzy copy. How can I
fix this (if at all)?
Hi Sam, I have no answer to this. Instead I add another remark. After
conversion, I always do
pdfimages infile outbase
for file in outbase*; do convert $file $file.tif; done
for file in outbase*; do tesseract $file $filep.pdf -l lang pdf; done
pdftk cat outbase*.pdf cat output final.pdf
which makes again a full-text searchable PDF. It looses 60% of its
over-size at the same time.

Thanks for that tip. I wonder if anyone has looked at scraping the
original text out of the pdf during conversion... returning it to the VM
with only safe text allowed and then combining with the sanitized pdf.
Qubes already has some text-sanitizing code, so the basic idea should be
sound.
