Convert PDF uploads to Images
Reported by Brian Michalski | June 5th, 2010 @ 01:57 PM
PDF file uploads should be converted to images which can be displayed. The pdf file should be saved as the 'original' and the converted image should be stored as the 'image'. Concerto 1.x uses a command line utility to do this, possibly pdf2jpg?
These sort of upload conversions should NOT be in the controller, preferably in a library or module so additional conversions can easily be added.

This could probably just be resolved by using RMagick. I just tested the following code which seemed to accomplish what you want.
pdf = Magick::ImageList.new("test.pdf")
pdf.write("test.jpg")Multi-page pdfs get named test.jpg.0 etc

Nice find August! This is much cleaner than our command-line system call a la V1.
