[sane-devel] [PATCH 3/4] canon: Add support for Canon IX-4015 scanner

[Ondrej Zary]

This adds support for Canon IX-4015 scanner. The difference from other scanners
supported by this backend is that it has no highlight and shadow settings - the
corresponding bytes in set_window command must be zero or it will fail.

IX-4015 has optical resolution of 400 dpi, can interpolate up to 800 dpi (color)
or 1200 dpi (grayscale).
