- round pixels_per_line down to arbitrary limits for fi-4990 & fi-4860
- fi-4860 returns random garbage to serial number queries
- initialize *info to 0 in sane_control_option()
* doc/descriptions/fujitsu.desc: backend v85, improve status/comments
* frontend/scanimage.c: initialize *info, fix buffer overwalk
- add all documented request sense codes to sense_handler()
- fix color jpeg (remove unneeded BGR to RGB swapping code)
- add macros for LUT data
* backend/canon_dr.conf.in: add DR-2080C usb ID
* doc/descriptions/canon_dr.desc: backend v10, add DR 3020
- rename read/send_counter to read/send_panel
- enable control panel during init
- add options for all buttons
- call TUR twice in wait_scanner(), even if first succeeds
- disable rif
- enable brightness/contrast/threshold options
* doc/descriptions/canon_dr.desc, doc/sane-canon_dr.man: backend v8
On Ubuntu getlogin() returns NULL. So we noew first try getlogin()
and if that fails, we try getenv("USER") and if that fails we use
a defaul user string
- jpeg support (size rounding and header overwrite)
- call object_position(load) between pages even if buffering is on
- use request sense info bytes on short scsi reads
- byte swap color BGR to RGB
- round image width down, not up
- round image height down to even # of lines
- always transfer even # of lines per block
- scsi and jpeg don't require reading extra lines to reach EOF
- rename buffer option to buffermode to avoid conflict with scanimage
- send ssm_do and ssm_df during sane_start
- improve sense_handler output
* doc/descriptions/canon_dr.desc: backend v7
doc/descriptions/canon_dr.desc: backend v5
- remove EOF ejection code
- add SSM and GSM commands
- add dropout, doublefeed, and jpeg compression options
- disable adf backside
- fix adf duplex
- read two extra lines (ignore errors) at end of image
- only send scan command at beginning of batch
- fix bug in hexdump with 0 length string
- DR-7580 support
- round binary bpl and Bpl up to byte boundary
- use s->params instead of user data in set_window()
- read_from_scanner() only grabs an even number of lines
* Pixma backend (pixma.c/pixma_common.c/pixma_io_sanei.c/pixma_bjnp.c)
bjnp tcp connection is now de-activated after initialization and
re-activated at start of scanning. If we do not do this, the scanner
closes its side of the connection after 30 secods of inactivity.
Added a maximum to the retry of slect calls when signals are
received
Added blocksize detection for tcp read_bulk call
* backend/pixma_bjnp.c
Added retry to select() calls when they get interrupted by a
signal. This solves problems in xsane after a first scan completed.
There is still an issue that scanner closes tcp connection after
30 seconds of inactivity
backend/pixma_bjnp.c backend/bjnp_private.h
Marked local functions as static and removed them from ..private.h
