Well, as mentioned in the README, if parts of the
image seem to be shifted horizontally this is
probably not related to the line distance/color
separation but to buffer overflow. If you have your
harddisk connected to the same SCSI controller there
is probably no solution. Otherwise the only cure
I can suggest is to kill *EVERYTHING* not absolutely
necessary for scanning and to disable swapping.
Or, to patch the kernel to allow a request size of
16 MByte, say, and then to change (in mustek.c)
#define BUFFERS 32
to
#define BUFFERS 1
And, I will check whether 'touching' all pages belonging
to buffers used by the backend prior to start scanning
helps.
