[sane-devel] A couple issues with genesys HP G4010

I'm using the Lineart mode and trying the --swdespeck option and I've
noticed its leaving a black band along the bottom of the image.

The 2nd issue, is that when I turn the debug up ( SANE_DEBUG_GENESYS=10 )
and try the same scan, the process seg faults. The following is the stack
from the core:

(gdb) bt
#0  0x00007fa3e4ce35c8 in sanei_genesys_write_pnm_file
(filename=0x7fa3e4cec479 "unprocessed.pnm",
    data=0x7fa3e2267000 <Address 0x7fa3e2267000 out of bounds>, depth=1,
channels=1, pixels_per_line=2360, lines=3188)
    at genesys_low.c:144
#1  0x00007fa3e4caa60f in genesys_buffer_image (s=0x99e340) at
genesys.c:6895
#2  0x00007fa3e4caccab in sane_genesys_start (handle=0x99e340) at
genesys.c:7864
#3  0x00007fa3eae33ae2 in sane_dll_start (handle=0x99b2a0) at dll.c:1263
#4  0x00007fa3eae20d38 in sane_start (h=0x99b2a0) at dll-s.c:48
#5  0x0000000000406d1c in main (argc=13, argv=0x7fffe2b73a08) at
scanimage.c:2283

 The code is trying to write out a file ( unprocessed.pnm ) containing ... I
think the Lineart converted data before performing the despeck process.

I'd be happy to help with a fix for this, or provide further information or
testing.

Thanks,
Brian ..
