Hello,
I am wondring if something has changed in the API to the pnm driver.
I'm running Sane 1.0.22 on Mac OS X and the command line scanimage
works fine with the PNM driver at index 0 (pnm:0).
But when I access it through the Sane.pm Perl interface to sane I get
no data on the read() call. The
Can you try to get some debug logs of the backend, to compare the two programs?
SANE_DEBUG_PNM=255 scanimage ... 2 scanimage.log
SANE_DEBUG_PNM=255 perlprog ... 2 perlprog.log
Maybe the perl code needs an additional call somewhere, or maybe there
is a bug in the backend.

OK. I'm going to have to set-up a separate test program for the Perl
part because the calls are embedded in some complex code. Will be back
shortly...

What happens if you call sane_get_parameters in your perl code, after
sane_start?

I think I solved it, and it has to do with the maxlen param on the
read(). If I use (0) it fails but if I use 32768 it works. On other
scanners the 0 is equivalent to the maxlength but in the PNM it seems
to need to be explicit.

OK. We thought that 0 was equivalent to max length on that arch.
