@ -121,6 +126,33 @@ that it loads. Usually that's the dll backend. If more information about
|
|||
the version numbers of the backends are necessary, the DEBUG variable for
|
||||
the dll backend can be used. Example: SANE_DEBUG_DLL=3 scanimage -L.
|
||||
|
||||
The
|
||||
.B --batch*
|
||||
options provide the features for scanning documents using document
|
||||
feeders.
|
||||
.B --batch[=FORMAT]
|
||||
is used to specify the format of the filename that each page will be
|
||||
written to. Each page is written out to a single file. If the FORMAT
|
||||
is not specified, the default of out%d.tif will be used.
|
||||
FORMAT is given as a printf style string with one integer
|
||||
parameter.
|
||||
.B --batch-start=#
|
||||
selects the page number to start naming files with. If this option is not
|
||||
given, the counter will start at 0.
|
||||
.B --batch-count=#
|
||||
specifies the number of pages to attempt to scan. If not given,
|
||||
scanimage will continue scanning until the scanner returns a state
|
||||
other than OK. Not all scanners with document feeders signal when the
|
||||
ADF is empty, use this command to work around them.
|
||||
With
|
||||
.B --batch-increment=#
|
||||
you can change the amount that the number in the filename is incremented
|
||||
by. Generally this is used when you are scanning double-sided documents
|
||||
on a single-sided document feeder. A specific command is provided to
|
||||
aid this:
|
||||
.B --batch-double
|
||||
will automatically set the increment to 2.
|
||||
|
||||
As you might imagine, much of the power of
|
||||
.B scanimage
|
||||
comes from the fact that it can control any SANE backend. Thus, the
