scanadf2docspell's Issues

Please migrate to scanimage

Hi,

on the distro I use is not scanadf (sane-frontends package with scanadf) available. I'm also unable to get the required patch for sane.

However scanimage is still maintained, available on Arch and uses almost the same paramters as scanadf, but the ppm format isn't supported.
Supported formats are pnm|tiff|png|jpeg|pdf.

I replaced scanadf with scanimage and added format parameter and it failed at converting to pdf.
