- add simplified Hough transform based deskewing code
- add extremity detecting cropping code
- use per-model background color to fill corners after deskew
- request and chop extra scanlines instead of rounding down
- remove padding dumb scanners add to top of front side
- sane_get_params uses intermediate struct instead of user struct
- if scanner stops, clone the last line until the end of buffer
- reset some intermediate params between duplex sides
- add software brightness/contrast for dumb scanners
- add blocking mode to allow full-page manipulation options to run
- add swdespeck option and support code
- add swdeskew and swcrop options (disabled)
- crop/resample image data before buffering, not after
- shink image buffers to size of output image, not input
- correct some debug message
- better handling of EOF
- add intermediate param struct to existing user and scan versions
- change 300 dpi mode to be in 'half ccd' mode
- fix sensor pixel number
- allow for negative offset in shading data building
- rewrite compute_coefficients to handle negative offset and specialised
it for pixel deletion case
- fix calibration handling of flatbed scanners
- added search_strip function to command set
- coded search_strip for gl646
- initial calibration process for sheetfed scanners upto strip finding
- create a scanner calibration function that switches between
flatbed or sheetfed calibration
- added a sheetfed calibration function
- removed gamma table setting from calibration process
- call gamma setting during sane_start but before scanner calibration
- change sanei_lexmark_low_set_scan_regs to have a resolution parameter
- cap sanei_lexmark_low_set_scan_regs resolution to sensor max dpi
when calibrating
Enable infrared, remember to alter the #ifdef in sane.h
and use tiffscan svn to test.
http://code.google.com/p/tiffscan/
tiffscan --device ... --scan --autofocus --ae-wb --depth=12 --infrared=yes
Adds infrared support for GT-X800 and GT-X700. Can be tested
by enabling the infrared frame type in sane.h and using
tiffscan (http://code.google.com/p/tiffscan/)
tiffscan --mode=infrared --scan
Color correction profiles have been imported from the epkowa driver.
The user can specify his own or let the backend choice. The
feature is not enabled by default.
This feature is in beta stage, works only for color scans
and automatic mode.
Enable with --color-correction 'Automatic'
- add fine cal support for machines with internal buffer (2050/2080)
- support fixed-width machines that require even bytes per scanline
- pad end of scan with gray if scanner stops prematurely
- better handling of errors during calibration
- cleanup canceling debug messages
- remove old cancel() prototype
