Hi Michael,
I found this thread in the SANE mailing list archive.
I already implemented ir scan for my CS9000F (pixma backend).
Now I'm searching an open source program and/or lib for processing ir data
against the rgb scan. Fortunately my scanner provides pure dust images without
any shadows
I learned from other posts in this list that SANE does not provide much
support for infrared. In sane.h some related definitions are even
commented out. Only in coolscan.c I have found some RGBIfix routines by
Andreas Rick which must be related to what he describes on his page at
Excellent description of both the problem, and the solution. I wrote
sanei_magic to contain exactly these sort of routines. Though, you
could also add a sanei_ir or some such, if you want a more 'private'
playground :)
