  Hi,

  As a reminder: This is the time table for sane-backends and
  sane-frontends 1.0.5:

  Now: Add backends and features, fix bugs, add documentation
  2001-06-04 Feature freeze. Only bug fixes and documentation
  updates.
  2001-06-24 Code freeze. Very important bug fixes only. Prepare
  for release.
  2001-07-01 Release.

  This is the TODO file for sane-backends. Backend maintainers who want
  to add their backends to SANE please don't do that only one or two
  days before feature freeze. It would be nice to have enough time to
  test the backends and fix compilation and runtime problems.

  TODO (2001-04-22)

  ******** todo ********

  backends
  --------
  * Configuration problems:
  - add options "--exec-prefix=...." and "--prefix=..." compareable
  to gtk-config

  - add warning when prefix dir is not listed in /etc/ld.so.conf on
  linux systems may be there is a general way to test this if the
  destination library directory is in the search path of the
  linker. [The correct fix is to use -R (on Solaris) and -rpath
  (on the rest?) to include the dynamic link path in the binaries
  / libraries. pere 2001-02-09]

  * Add new backends (?)
  - Polaroid SprintScan 35 LE [should be included into microtek]
  Dick Bruijn <dick@wau.mis.ah.nl>
  - primax http://primax.sourceforge.net/
  - hp4200 http://hp4200-backend.sourceforge.net/
  - v4l2 http://video.inodes.org/sane-v4l2/
  - Relisys Scorpio Super 3 SCSI II
  Mark Plowman <mplowman@wxs.nl>
  - Linux Handscanner Ioctl Interface scanner by Harald
  Bauer <hbauer@online.de>
  - viceo (Visioneer OneTouch 8600)
  http://www.abaforum.es/martim/bird/otlinux.htm
  - Mustek 1200 UB backend
  ftp://ftp.mustek.com.tw/pub/driver/1200UB/Linux/
  - bearpaw (Mustek BearPaw 1200 + maybe 2400)
  Henning Meier-Geinitz <hmg@gmx.de>
  - UMAX 1220P/2000P & HP 320C
  http://umax1220p.sourceforge.net
  - Genius Vivid Pro USB, Colorado USB 19200, Visioneer OneTouch 7600
  IBM IdeaScan 2000 USB
  http://homepages.paradise.net.nz/stevenel/scanner/

  * Update backends
  - add additions/bug fixes to microtek2 from Karsten Festag
  <karsten.festag@t-online.de> (partially done)
  - include snapscan updates http://sourceforge.net/projects/snapscan

  * Use DBG(...) instead of fprintf(stderr, ...) or printf
  - microtek

  * Check net/saned
  - sometimes saned+net freezes right after a scan
  - don't just ignore the byte-order for the image data (needed to
  support depths > 8 bits/channel)
  - Add keep-alive mechanism to avoid timeouts

  * 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
  * qcam: figure out how/if to support bulb mode

  * qcam: convert to use sanei_pio functions instead of direct port
  access.

  * qcam: Check file handling in /tmp.
  * dc210 and jpeg stuff: move sanei_* functions to sanei/ (if they are
  necessary).

  * nec: Remove references to sharp backend (grep for "JX").

  * nec: Check for HAVE_SYS_SHM_H before including sys/shm.h and
  disable shared memory support if 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() do not release memory allocated by
  sane_get_devices().
  - qcam
  - etc?

  * as6e: change :new status to :alpha, :beta, or :stable.

  * add a contact address for each backend (in backend.desc).

  doc

      ---
        * Add sane manpage (this is work in progress: Henning Meier-Geinitz
                            <henning@meier-geinitz.de>)
           - versioning system?
           - SANE API (maybe summary only?)
           - point to backends and other information?
        * Add sane-usb manpage
        * Documentation for sanei API
          - any ideas for this?

        * install all documentation that's available
      frontends
      ---------
        * dll: Rewrite to use libtool ltdl library
        * Add a check in the frontends if the backend delivers more data than
          it announced by sane_get_parameters to avoid segfaults with bad
          backends?
       [the remaining entries have been moved to the sane-frontends package]
      sanei
      -----
      misc
      ----
        * Remove compiler warnings (>300 warnings even in disable-warnings mode,
          >700 with --enable-warnings))
        * Test SANE on different os/platforms, fix possible compilation problems
           Test methods: scanimage -d pnm:0 --filename=file.pnm -T
                         scanimage -d net:localhost:pnm:0 --filename=file.pnm -T
                         (start saned by inetd or saned -d before testing)
                         xscanimage / gimp with xscanimage plugin (where available)
           All the above with shared and static libraries.
        * move .desc files for backends that are not included in SANE to
          different directory (e.g. backends and external-backends)?
        * Maybe add script to detect and deinstall existing sane versions
          - make uninstall
          - install sane-uninstall script. Advantage: uninstall possible
            without sourcecode
        * Use #include "../include/sane/..." instead of #include <sane...>
        * Use #include "../include/lalloca.h" instead of #include <lalloca.h>
        * 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.
        * Add USB support for sane-find-scanner.
      Bye,
        Henning
