Stéphane Voltz 79fbd0c2f1 - added OPT_CUSTOM_GAMMA and OPT_GAMMA_VECTOR* options for GL646 
- fixed allocation bugs detected by valgrind
	- fixed bugs detected by 'tstbackend -r 1 -l 1'
	- allow 'genesys' as default value for backend opening
	- made OPT_COLOR_FILTER effectively work for GL646 scanners
	- split sane_control_options() to make it more readable

Pierre Willenbrock 8d2069c0dd * backend/genesys.c, backend/genesys_devices.c, backend/genesys_low.h, 
backend/genesys_gl646.c, backend/genesys_gl841.c: add infrastructure for
  multiple motor power modes

Stéphane Voltz 825ff7335e * genesys/gl646: HP2400 warmup fix by Luke <iceyfor@gmail.com> 2007-08-26 09:49:18 +00:00
Pierre Willenbrock 6a7fb3235a * backend/genesys_devices.c: reduced height of calibration area 
* backend/genesys_gl841.c: fixed bug in offset calibration(offset values were
  not clamped to 0..255)

Pierre Willenbrock dba2f29195 * backend/genesys_devices.c: fixed gamma settings(1.0 now) 
* backend/genesys.c backend/genesys_gl841.c: improved calibration for dark
  shades

Stéphane Voltz 7ec4d9b567 - improved sanei_genesys_search_reference_point to fix origin detection 
for HP2300 and a left margin detection bug with MD6345
	- some HP2400 support tidbits
 2006-08-09 13:22:36 +00:00
Stéphane Voltz a6aceb99ac - tuned HP2300C geometry 
- added a safeguard against negative values when moving to scan target,
	  due to failed start position detection

Pierre Willenbrock feea058821 * backend/genesys_devices.c: Increase length of acceleration slopes for 
Canon LiDE 35/40/50/60

Pierre Willenbrock fb446b0804 * backend/genesys.c: removed usage of current_setup in functions 
where it is not necessarily initialized. Modified shading
	  calibration to not use fixed stripe sizes. Fixed memory
	  corruption while calculating shading data. Fixed read sizes to
	  be multiples of 256. Fixed stagger/line distance
	  correction. Fixed line shrinking to correctly update data
	  buffers. Bumped BUILD number.
	* backend/genesys.c backend/genesys_conv.c: Added gray to lineart
	  conversion.
	* backend/genesys.c backend/genesys_conv_hlp.c: Modified calling
	  parameters to stagger/line distance correction filter to better
	  describe its inner working.
	* backend/genesys_devices.c: Slowed down motor timings for
	  LiDE 35/40/50/60. Removed untested message for LiDE 35/40/50/60.
	* backend/genesys_gl646.c: Fixed bug for odd pixel count. Added
	  support for gray to lineart conversion.
	* backend/genesys_gl841.c: Fixed words_per_line calculation. Added
	  support for gray to lineart conversion(not used). Fixed problem
	  with scanners not backtracking while scanning calibration area
	  leading to scanning part of document area.

Henning Geinitz 79d2a16c78 Bumped build number. Changed scanner's name to Canon LiDE 35/40/50. Added Canon 
LiDE LiDE 60. This scanner is still commented out in genesys.conf. Removed
comment sign for Canon LiDE 35/40/50 in genesys.conf.
