65.5 PDF Conversions
20220710
ImageMagick provides considerable functionality for image conversion, including converting from pdf to png.
To convert from pdf to png a -denisty
of
300 and -resize
50% seems to work well:
convert -density 300 myimg.pdf -resize 50% myimg.png
This may fail due to an ImageMagick
security policy when the GhostScript interpreter is being used as in
the handling of pdf files. You may like to research the risk and
then override the policy by editting /etc/ImageMagick-6/policy.xml
to comment out the appropriate policy line:
sudo emacs /etc/ImageMagick-6/policy.xml
<!-- policy domain="coder" rights="none" pattern="PDF" / -->
