Hi,
This is the current TODO list for sane-backends:
Bye,
Henning
TODO (2002-01-19)
******** todo ********
backends
--------
* Add new backends (?)
- hp4200 http://hp4200-backend.sourceforge.net/
- v4l2 http://video.inodes.org/sane-v4l2/
- Relisys Scorpio Super 3 SCSI II
Mark Plowman <sane-devel at plowman.xs4all.nl>
http://www.xs4all.nl/~plowman/
- Linux Handscanner Ioctl Interface scanner by Harald
Bauer <bauer-h at web.de>
- viceo (Visioneer OneTouch 8600)
http://www.littlecms.com/iphoto/otlinux.htm
- Genius Vivid Pro USB, Colorado USB 19200, Visioneer OneTouch 7600
IBM IdeaScan 2000 USB
http://homepages.paradise.net.nz/stevenel/scanner/
- Fujitsu M3091DCd support
Frederik Ramm <frederik at remote.org>
http://www.remote.org/frederik/projects/software/sane/
- Canon FB620S flatbed scanner and FS2710 film scanner
ftp://stthd0.pc.uni-koeln.de/pub/canon-1.08.tar.gz
Ulrich Deiters <ukd at xenon.pc.Uni-Koeln.DE>
- Hewlett-Packard ScanJet 3300C / 3400C and 4300C (wip)
http://sourceforge.net/projects/hp3300backend
* Update backends
- Combine all the Fujitsu backends into one single backend
* All backends should check for TL_X < BR_X and TL_Y < BR_Y to
avoid segfaults or even scanner damage.
* Don't use exit() in backends.
- (v4l)
- tamarack
* Use DBG(...) instead of fprintf(stderr, ...) or printf
- microtek
* qcam:
- implement auto mode for brightness and black-level (don't
just advertise it!) Actually, implement an auto "backend" instead
that can be plugged in front of any backend with brightness/contrast
etc controls
- figure out how/if to support bulb mode
- convert to use sanei_pio functions instead of direct port
access.
- The result of locking isn't checked --> does it make sense at all?
* dll: Rewrite to use libtool ltdl library
* dc210 and jpeg stuff: move sanei_* functions to sanei/ (if they are
necessary).
* v4l: Problems (crash) with more than one video card. It looks like
the two different cards are identified as the same card.
* Fix backends where sane_exit() does not release memory allocated by
sane_get_devices().
- abaton
- agfafocus
- apple
- as6e
- avision
- bh
- canon
- coolscan
- dmc
- m3096
- microtek
- qcam
- ricoh
- s9036
- sharp
- sp15c
- tamarack
- etc?
* as6e: attach: memory (dev + dev-sane.name) isn't freed if driver isn't
found.
* avision: line 1393: word isn't freed sometimes (maybe if cp == line?)
* net: add IPv6 support.
doc
---
* Add doxygen documentation for the remaining sanei files:
- sanei_auth.c
- sanei_codec*
- sanei_config.c
- sanei_config2.c
- sanei_constrain_value.c
- sanei_init_debug.c
- sanei_net.c
- sanei_pa4s2.c
- sanei_pio.c
- sanei_pv8630.c
- sanei_scsi.c
- sanei_thread.c
- sanei_wire.c
* sane.tex: Define the return values for sane_init? Define the
consequences if sane_init doesn't return SANE_STATUS_GOOD.
* sane.tex: Add a warning/explanation about problems with
sane_get_select_fd, Unix select() calls and sane_cancel.
frontends
---------
* saned:
- saned times out after 60 minutes. Check if the
watchdog timer is really necessary (e.g. to avoid blocking scanners
by one user). Maybe add a command line option to saned to set the
timeout. Otherwise turn on TCP keep alive (where available) and
(maybe) check the connection from server side.
- Add IPv6 support.
* scanimage: Add i18n (NLS) support?
[the remaining entries have been moved to the sane-frontends package]
sanei
-----
* sanei_scsi: Check return values of req_wait and cmd in case of
SCSI DEVICE BUSY. Better specification of the behaviour of sanei_scsi
functions (e.g. return values, timeout 10 min versus 1 min)?
* create sanei_parport_* and remove all inb, outb,... from all backends;
use libieee1284 if available (see
http://people.redhat.com/twaugh/libieee1284/). Or just include this
library into sane.
platform-specific
-----------------
* Keep config.guess and config.sub up-to-date.
* SCSI access doesn't seem to work on Linux/Sparc. See emails from
Tomislav Renic on sane-devel (2001-09-21).
* Really fix all the parport/inb/outb compilation issues which break
porting to some non-i386 platforms.
* Add AC_OBJEXT and AC_EXEEXT to configure.in for automatically adding
the correct extensions (e.g. for OS/2). Also update the Makefiles
accordingly.
* Add support for semaphores also for OS/2 (currently used in snapscan).
* Fix shared lib problem with NetBSD. Starting scanimage results in:
"Cannot open "../backend/.libs/libsane.so".
* Shared libs work with OpenBSD. However, they are named libsane.so.1.6
instead of 1.0.6. Is this correct?
misc
----
* sane-config: add options "--exec-prefix=...." and "--prefix=..."
compareable to gtk-config
* Check include/sane/config.h.in for unnecessary macros.
* Add configure option to enable only the net backend for users without
local scanners. Install only sane-dll/sane-net (or even only sane-net).
Maybe something like --network-client-only or --disable-local-devices.
