If you own a scanner that isn't detected by the genesys backend but has a GL646
44
or GL841 chipset, you can try to add it to the backend.

The lamp will be turned off after the given time (in minutes). A value of 0 means that the lamp won't be turned off.

When using high resolutions where the horizontal resolution is smaller than vertical resolution,

77
.B \-\-color-filter None|Red|Green|Blue

When using gray or lineart this option selects the used color. Using a color filter

will give a monochrome scan. CIS based scanners can to true gray when no filter (None value) is
85
Additionally, several 'software' options are exposed by the backend. These
86
are reimplementations of features provided natively by larger scanners, but
87
running on the host computer. This enables smaller machines to have similar
88
capabilites. Please note that these features are somewhat simplistic, and
89
may not perform as well as the native implementations. Note also that these
90
features all require that the driver cache the entire image in memory. This
91
will almost certainly result in a reduction of scanning speed.

Requests the driver to detect the extremities of the paper within the larger
96
image, and crop the empty edges.

Requests the driver to detect the rotation of the paper within the larger
102
image, and counter the rotation.
105
.B \-\-swdespeck \-\-despeck X
107
Requests the driver to find and remove dots of X diameter or smaller from the
108
image, and fill the space with the average surrounding color.

130
166
some debug options become available that are normally hidden. Handle them with

care. This will print messages related to core genesys functions.

This environment variable controls the debug level for low level functions

common to all genesys ASICs.

This environment variable controls the debug level for the specific GL646 code
