There is now a PNG file in the temp directory, but I get this error:
Unable to determine total number of pages in PDF
Please enter total page count: 5
Temporary directory: /tmp/pdfread-6ktemb
Page 1/5: EXTRACT RASTERIZE CROP DILATE RESIZE
Please check that ImageMagick is installed.
I can run the 'convert' command on my system, so I do not know what is up.
Bummer. I hope helping me isn't too much of a problem.
