A friend of mine called me today telling me he had to open a file that ended in PDF, but he was not able, I guided him to install Adobe reader on his Windows XP computer, but it was not easy as I was not watching the same screens he was, so I preferred to convert his PDF to JPG.
He sent me the file via email, and with this simple line on my Arch Linux computer I converted the three pages PDF file into three JPG files.
convert -density 300 file.pdf file.jpg
You will have to install imagemagick first on you system, in Arch Linux was as simple as:
pacman -S imagemagick
I'll visit my friend this weekend to install Adobe PDF readers in his computer.
