Your can use ImageMagick (and may be GraphicsMagick)

For cli version install port graphics/ImageMagick-nox11

If ImageMagick compiled with pdf support convert tool can read pdf and 
write raster image.

See my script as example:
https://bitbucket.org/citrin/scripts/src/tip/split-image.sh
And modify for your task if need.
