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.
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.
