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'
The code flow has been modified to avoid unnecessary probing
and double opening of a device. There's no more delay before
opening a networked scanner and the whole scan process begins
much earlier.
Accepted device names are:
net:ipaddress
net:hostname
libusb:vendor:product
pio:0xnnn
plus any form supported by the SANE scsi and usb
routines.
The code has been tested on network, scsi and libusb. Unfortunately
I do not have any parallel port based scanner.
Error checking has been added when receiving the network
header and welcome message. Timeout has been added too and
a wrong buffer size has been corrected.
Image inversion is something that can be handled by a frontend,
in the epson2 backend I want to avoid to add any complexity
that doesn't belong to the hardware.
Internationalized backend options lead to incompatible shell
scripts, so they've been removed. A trailing dot has been removed
from some descriptions and a few includes moved around.
The probing code has been streamlined and is now more maintenable.
The backend will probe when required and the get_devices hook can
be called multiple times. Transfer buffers are now selected based
on the connection type.
Sometimes a "fatal error" is given back when the scanner is warming up.
The previousversion of the code checked for that issue only when
the ADF was in use.
Some subroutines have been moved from epson2.c to epson2-ops.c and
there's also a temporary fix for the networking code.
This is work in progress but should work.
Source code was inconsistent on how they were referencing
include files in include/sane. In certain cases, sane/sane.h
and sane/saneopts.h was really including external copies (with
some preprocessor implementations anyways).
sanei/sanei_tcp.c, sanie/sanei_udp.c: Improve portablity by
removing usage of MSG_WAITALL since not all platforms support
that (cygwin). Default is to be blocking anyways. Changed
usage of MSG_NOTWAIT to use fcntl() function as needed as well.
* configure.in, lib/Makefile.in, lib/strcasestr.c: Add internal
strcasestr() for platforms missing it (cygwin).
* pixma_common.c: My source match header prototype for picky
compilers (cygwin).
* backend/umax_pp_mid.c: Allow BACKEND_NAME to be filename
yet debug to be SANE_DEBUG_UMAX_PP to match man page.
out in attach(). Otherwise the backend sends inquiry data to fd 0, which it
obviously shouldn't do; this breaks scanning over saned.
Thanks to Giuseppe Sacco who experienced the issue and pointed to epson2 as
the probable cause.
the job of a frontend to provide such a commodity.
removed confusing parameters (preview-speed, speed).
when a preview is requested, the scanner will be
set to high speed (if possible).
removed references to the never implemented zoom function.
the function that shortened the list was actually
missing the first entry.
more resolutions addedd for networked scanners.
added support for Perfection 4990 (Claus Boje).
in multiple files, added networking
support, added FS G extended handshaking mode,
make proper use of extended commands when possible
* sanei/sanei_tcp.c: read now wait until all
the requested data is available.
