Hi.
|
|
<BR>
|
|
<P>The suggested way is an option "mode" (SANE_NAME_SCAN_MODE in saneopts.h).
|
|
<BR>
|
|
E.g. the umax backend uses scanmodes "Color", "Gray" and "Lineart".
|
|
<BR>
|
|
There are other backends that do it the same or a similar way.
|
|
<BR>
|
|
But pay attention that this is not defined as a well known option
|
|
<BR>
|
|
in the current sane standard.
|
|
<BR>
|
|
<P>Bye
|
|
