[sane-devel] Pixma MP600 broken by 1430217e1919801fa6418c36589cc4360e5f1779

[Tomáš Pospíšek]

Hello sane developers,

current Debian libsane [1] - the to be released next stable Debian - 
doesn't work with Pixma MP600. I tracked the problem down with great help 
from Julien Blache [2] and the patch that broke scanning is

   1430217e1919801fa6418c36589cc4360e5f1779

How to reproduce the problem:

* start xsane
* click on "Preview"
* click on "Scan"
-> immediately a "Operation was cancelled" popup apears

I have looked at that patch however I can't see much standing out, except 
that the code introduces cropped regions.

Since I'm not a scanning expert I'd be *very glad to get some direction* 
to debug and try out changes further so that newer and older Canon's 
continue to work.
