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.
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.
Implemented support for latest Avision ASICs and features,
including overscan, background raster, software scaling for
cheaper ASICs used in HP scanners. Changed types used to
more portable uint* ones, without underscore (_), removed
in-file ChangeLog history, as the files became big enough.
Implemented early calibration for easier handling of
Avision-based film scanners and implemented support for
2-pass duplex scanners.
from BUILD 167 to 179, including support for HP 5370, AV600U,
AV210C2, AV220C2, et. al. The USB i/o paths got hardened, and a
lot of fixes as well es enhancements and optimizations where added
and a lot of typos, mostly in debug output and comments, got fixed.
The "Line Art" mode was renamed to "Lineart" to match the other
backends.
fixed segmentation faults for some modes, many many new devices, two
different duplex modes are supported, vast speedup of multi page batch scans,
buttons as well a 7-segment LED readout and some quirks for old scanners not
filling all fields
wait_4_light bugfixes, fixed color packing, fixed 16bit modes
(especially for big-endian systems), avoid 16bit modes for default
modes, fixed gamma-table for some models as well as spelling on the
way
* backend/avision.h, backend/avision.c: the current development state,
including cleanups, code refactoring, dynamic color and scan source
list creation, implemented ADF mirroring needed for some ASICs ,
some scan window scaliing fixes for some ASICs, added 16bit gray
and color support, fixed a tiny big-endian issue, fixed command
error reporting for some ASICs, improved inquiry logging and some
tiny fixes for film-scanners.
Sorry for such a bit chunk so late in feature freeze (...). But tested on Ultra
SPARC, PowerPC and x86 Linux ... ;-)
endianess fixes, calibration code, ADF detection, correct lamp warmup,
gamma table for new ASICs, some workarounds for ASIC variations and the
convertion to use OPT_SOURCE instead of seperate OPT_ADF and OPT_TRANS.
to copy it over and over again. Changed header inclusion order in backend
files to include backend.h after sanei_backend.h. Based on a patch from stef
<stef-listes@wanadoo.fr>.
