Same applies to interpoliation. I have a huge patch in my inbox that
adds scaling to my avision backend just because some el-cheapo OEM
scanners do not appear to deliver any resolution - and for the highest
resolution of 2400 dpi have a memory shortage and thus the author
implemented amorphic scans @1200x2400 with software scaling to
2400x2400 to compensate this.
In the long run some plugin subsystem (think ALSA) to plug scalers
together would be a big win. Trivially one could implement this by
adding a backend (simillar to the dll one) with that functionality
shadowing any other backend.

Thanks - this is very much welcome. Now with the basic code for
the HP5370 / AV600U, with this long outstanding shifting image
problem, the avision code should be read to be merged in. I'll
commit it this weekend.
I also have this "pass data thru a pipe feature" for scanadf
lingering around. I'll also finally rediff taht (I assume it
was not yet merged by anyone). Is there a new frontends
version planed any time soon?
Yours,

There are no plans at the moment as n ochanges have been committed
since the last release until now.
