Support for reading PDFs

[mgalgs]

Are there any plans to add read support for the PDF format?

Yours is the first request I've heard.

It looks like it could be hacked in through ghostscript and the EpsImagePlugin without too much effort.

Just throwing the idea out there - rather than Ghostscript, this could also be done using ImageMagick, which has a more permissive license from my reading.

It's also worth noting that a consequence of the EPS conversion method would be that transparency is lost.

Just to note this here - I previously attempted to add support for opening PDFs, and encountered resistance to the idea of using other software to convert PDFs to another format. So perhaps this requires a more thorough approach.

It is possible to use Pillow to extract images from a PDF - #3491 (comment)
