[sane-devel] Button support for Canon PIXMA MG6250 and MG6350

[Rolf Bensch]

Hi,

Based on the latest git version I added a new parameter to button
support: --scan-resolution.

Please patch all files from the archive file and test button support
with 'scanimage -A'. Now you should be able to get the dpi info from
your scanner.

If you like you can also patch doc/sane-pixma.man and check if the
description of the button parameters are ok your scanner.

Please report if the patch is working. Then I can commit this into git.

Many thanks for your help,
Rolf
