Seb presents: Acer 300f Mega Power Patch 2000 (see end of mail)
It adds support for the Acer 300f and corrects a bug that put noise on
the major part of the picture when scanning.
The interesting part in itself is only 2 lines long! (but you can't
imagine what I had to do to find those two missing lines)
I think this patch can solve the same problem reported for some other
models as well. To do this, search for ACER300F in snpascan-scsi.c and
snapscan.c and add your model in the "if" test (I didn't do it myself
in order not to break support for working scanners).
This is not a complete correction however:
* it removes gamma correction for this model (who cares?)
* while the picture looks fine most of the time, I have problems with
big pictures in high resolution; in 300dpi GreyScale the scanner needs
to stop and go back producing a picture with traces; in 300dpi Color,
the scanner blocks in the middle of the scan.
This problem is probably the same reported by Lawrence Glaister
before, but his proposed correction doesn't work in my case.
Enjoy
