with partial matches on USB ID, but vendor / product string
matches as mostly only the HP5300 vs. HP5370, fixed non-color
calibration for devices not filling all RGB fields of calibration
format information, do not send 3x3 color matrix to older devices
(ASIC versions) as some HP53xx does not correctly handle it,
improved calibration accuracy and fixed transparency adapter
detection to not use non-zero as present, but just 1 (some
devices now set 0xff as (-1) - not present ...
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.
options from the parser, example avision.conf and manual page.
Fixed 12 Bit gray and color modes to actually work as well as
software CCD line-difference correction. Minimal scan resolutions
have been slightly adapted for some ASICs.
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.c doc/descriptions/avision.desc doc/sane-avision.man: substituted my mail address and web-site to a new one - due to
leaving the rocklinux project
* 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.
