Joining multiple JPEGs into a multipage PDF
If you ever wondered how to convert multiple JPEG files (e.g. some
scanned in pages) into one big PDF file, and not all of these have the
same resolution, you might have had a hard time figuring out how to do
this with free software under Linux. Here is the solution:
First, convert each invidual JPEG into a PDF:
for I in *.jpg; do BASE=`echo $I | sed -e
's/.jpg//'`; convert "$BASE.jpg" "$BASE.pdf" ; done
Then, join all the PDFs together into one big document:
pdftk first.pdf second.pdf third.pdf fourth.pdf cat
output combined.pdf
Using this combination of tools gave the best results for me, far
superior to any in-between conversion to postscript or importing
everything into The Gimp first and saving as PDF from there.h
