* backend/pixma_mp150.c:
|
||||||
|
Updated pixma backend to have MP970 (tested), and probably other
|
||||||
|
CCD sensor MPs, working for Grayscale scan.

|

|
(new) backend/pixma_imageclass.c, backend/Makefile.in:
|
||||||
|
Thanks to Dennis Lou, who adapted the pixma backend to add support
|
||||||
|
for Canon ImageCLASS series, fully tested for MF4270, and includes
|
||||||
|
PIDs declarations for other ImageCLASS devices, yet to be tested.
|
||||||
|
Fixes also a bug for ADF and ADF Duplex scan source selection.

|

|
||||||
|
2008-04-19 m. allan noah <kitno455 a t gmail d o t com>
|
||||||
|
* backend/fujitsu.[ch], backend/fujitsu-scsi.h: backend v1.0.58,
|
||||||
|
rename page code 32 to 'unknown', compile if NDEBUG is set,
|
||||||
|
proper async sane_cancel support, re-enable JPEG support
|
||||||
|
various functions rewritten (shorter, more clear)
|
||||||
|
* doc/descriptions/fujitsu.desc: add new fi-6xxx machines
|
||||||

|
||||||
|
doc/sane-pixma.man, doc/descriptions/pixma.desc:
|
||||||
|
With feedback from MP970 owner, updated pixma backend for MP970
|
||||||
|
CCD sensor support (yet in color only), and more generally,
|
||||||
|
support for other CCD sensor PIXMA: MP800, MP810, MP830, MP960,
|
||||||
|
but yet untested, which produce shifted color planes
|
||||||
|
scanned images. Current trim based on sample images provided
|
||||||
|
in bug reports and other web pages, but might require some
|
||||||
|
few and simple final tweaks.
|
||||||
|
Also fixed a bug for MP220 at 1200 dpi, MP220 is now reported
|
||||||
|
to work fine.

|
||||||
|
* frontend/saned.c: fix typo.
|
||||||
|
* backend/net.c: plug an information leak in the net backend. When
|
||||||
|
sending out a SANE_NET_CONTROL_OPTION RPC for the
|
||||||
|
SANE_ACTION_GET_VALUE action (and SANE_ACTION_SET_AUTO for the
|
||||||
|
network protocol versions < 3), the backend was not clearing the
|
||||||
|
memory area for the value argument before sending it over the
|
||||||
|
network, resulting in an information leak for the
|
||||||
|
SANE_ACTION_GET_VALUE case.

|
||||||
|
* backend/rts8891.c, backend/rts88xx_lib.c: fix format warning
|
||||||
|
* doc/sane-rts8891.man: man page fixes
|
||||||
|

2008-04-11 Julien Blache <jb@jblache.org>
|
||||||
|
* frontend/saned.c: announce the _sane-port._tcp service via mDNS
|
||||||
|
(Avahi) when running in standalone or debug mode. A separate
|
||||||
|
process is responsible for the announcement through Avahi.
|
||||||
|
* backend/net.c: look for _sane-port._tcp service announcements
|
||||||
|
via mDNS (Avahi). A separate thread listens to announcements
|
||||||
|
through Avahi. Start the thread as early as possible in
|
||||||
|
sane_init() so as to get as much data as possible until
|
||||||
|
sane_get_devices() is called.
|
||||||
|
* aclocal.m4, configure, configure.in, include/sane/config.h.in:
|
||||||
|
add autofoo stuff for Avahi support, disabled by default.
|
||||||
|
|
||||||
|
2008-04-10 Julien Blache <jb@jblache.org>
|
||||||
|
* frontend/saned.c: do not use daemon(), as it's a 4.4BSD/glibc
|
||||||
|
function; OS/2 for instance does not have it. Use an open-coded
|
||||||
|
equivalent. Add a PID file. saned -a username now drops privileges
