35.13 Converting Images
20200423 ImageMagick provides considerable functionality for image conversion. Below we include some examples.
To convert from pdf to png a
-denisty of 300
-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
to comment out the appropriate policy line:
$ sudo emacs /etc/ImageMagick-6/policy.xml <!-- policy domain="coder" rights="none" pattern="PDF" / -->
