Added support for the Avision AV210D2+ scanner. This is the first scanner
to require the use of the gray filter bits, so code was added to enable them.
Regenerated description file to reflect this change.
Moved device init code from sane_init() to the newly created
sane_reload_devices() function, which is now called from sane_get_devices().
This means that device initialization now happens when sane_get_devices() is
called, not when sane_init() is called.
Replaced the clever, yet totally confusing, code using the "adf_mode"
variable. This variable was used with a complex interaction of bit shifts
and subtraction indirectly influnced by the value of s->source_mode. The
replacement code direct references s->source_mode instead, simplifying
things greatly. This change is functionally identical.
As a side note, the adf_mode code allowed "ADF Rear" scanners, in addition to
"ADF Duplex" scanners, to enter the section of code normally used for (HP)
duplex scanners. It's not clear if this was the intended effect, or if, as
the comments suggest, this was an unnoticed side effect caused by the
confusing code. The point is moot, however, because prior in the code, the
ADF Duplex flag is set anytime the ADF Rear flag is set. As long as all
ADF Rear scanners are duplex scanners this shouldn't be a problem.
Changed the AVISION_FILTER_* defines to their final values rather than
bit-shifting them prior to use. This make reading the code much easier
since no mental calculation is necessary to determine what the final
bit-pattern/value will be.
Wrap scanner entries with duplicate USB ids with ifdefs so they will not be
compiled. This shortens the search for new scanners because we don't try
the same USB id more than once.
create a place holder for low level commands
move low level functions to genesys_low.c

all mods done, ready to test
set fe OK
GL124 WIP : ready to test scans
GL124 WIP
GL124 WIP
- fixed analog fe issue: don't put afe regs in global set
GL124 : first light at 300 dpi
GL124 WIP
- 300 and 600 uncalibrated mostly ok (x coordinate rounding)
- 150 and 75 OK x-wise, y to be solved
solved rounding errors for gl124
re-add 400, 200 and 100 dpi modes
GL124 : tous x dpi OK
before adding line cropping
GL124 : line cropping almost finished
GL124 WIP : working line deletion
compute step rework
GL124 WIP : high speed table for dpi <= 300
move to scan area working
line skipping fix
new slope table for 600 dpi base
geometry and movement tuned
GL124 WIP : shading calibration almost working
working 600 dpi shading
GL124 : working shading calibration for all modes but 1200 dpi
working 1200 dpi shading
beta 1 of GL124 support
last tuning
update genesys.desc for LiDE 110
motor slope and start area tuning
shading coefficient computing clean up
add support for GL124 based CanoScan LiDE 110
feed almost OK up to 300 dpi
feeding is fixed
all issues fixed
the same and already work, but this change will reflect that fact on the
website.
- Generated a new version of doc/descriptions/avision.desc from avision.c.
the AV610, and added a comment for the @V5100 in avision.c.
- Generated a new version of doc/descriptions/avision.desc from avision.c.
This restores information lost with my last update. I've intentionally
seperated these changes so that they can be more easily understood.
but somehow got re-added again.
- Generated a new version of doc/descriptions/avision.desc from avision.c.
This change merely updates the .desc file, the driver code remains unchanged.
- backup and restore image params around image processing code
- cache software crop/deskew parameters for use on backside of duplex
- fi-6110 does not support bgcolor or prepick
