hope you at least understand the English answer ... this is an
international list ... If writing directly to me, you can of
course write in German ,-)

Gimp: is only for Image manipulations ... like Photopaint(Tm) or Photoshop(Tm)
SANE: is a scanner framework like TWAIN under Win
XSane: is a frontend for SANE
the other stuff you mentioned is unkown to me ...
but to make it short ... nothing of these programs is needed to use your
scanner.

this is the original scanner program by Marco, Thomas and me. There's
no need for any further program in order to scan with your scanner.

is a SANE backend by Andre Herms. It's based on an earlier version of our
primax_scan ... and is a standalone project not depending on primax_scan,
but needs SANE.

PrimaxGUI is a frontend for primax_scan to make scanning much easier.
it has its own version numbering. This program is recommanded for use
with primax_scan

never heard about this ... and not using it ... so I guess: no it's not
required ,-)

the XML stuff is only needed for primaxd
libtiff is needed by primax_scan

the -ljpeg and -lz are command line parameters for the compiler/linker ...
not for finally compiled program.
To see the parameters of primax_scan type primax_scab --help

yes. that's a problem. Newer versions of libtiff don't support LZW compression
anymore.
use primax_scan -C 0 to switch off compression.
