backends
 | 
						|
--------
 | 
						|
  * Add new backends (?)
 | 
						|
    - hp4200 http://hp4200-backend.sourceforge.net/
 | 
						|
    - v4l2 http://video.inodes.org/sane-v4l2/
 | 
						|
    - Relisys Scorpio Super 3 SCSI II

 | 
						|
    - Linux Handscanner Ioctl Interface scanner by Harald
 | 
						|
      Bauer <bauer-h@web.de>
 | 
						|
    - viceo (Visioneer OneTouch 8600)
 | 
						|

 | 
						|
    - 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@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@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. This should NOT be done
 | 
						|
    in sane_control_option, it should be possible to temporary set
 | 
						|
    TL_X > BR_X or TL_ > BR, otherwise it is hard for a frontend to
 | 
						|
    set the correct values.
 | 
						|
 | 
						|
  * 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, dc240, gphoto2, 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: Think about a completeley new interface. Details are in
 | 
						|
    http://www.mostang.com/pipermail/sane-devel/2002-January/001995.html .
 | 
						|
 | 
						|
  * 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". However, scanadf works.
 | 
						|
 | 
						|
  * Shared libs work with OpenBSD. However, they are named libsane.so.1.6
 | 
						|
    instead of 1.0.6. Is this correct?
 | 
						|
 | 
						|
  * Check if a new version of libtool can fix the above mentioned issues.
 | 
						|
 | 
						|
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.
 | 
						|
 | 
						|
  * Make output of sane-find-scanner more flexible. See scanimage -f for
 | 
						|
    details.
 | 
						|
 | 
						|
 | 
						|
******** done ********
 | 
						|
* Don't use exit() in backends.
 | 
						|
* 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)?
 | 
						|
* Documentation for sanei API
 | 
						|
* Fix missing or wrong links to backend homepages (*.desc). If a homepage
 | 
						|
  doesn't exist, add a contact address (where available).
 | 
						|
* Check all backends which use fork/kill for the kill (-1,...) bug
 | 
						|
  first found in the microtek2 backend.
 | 
						|
* Add support for qt NLS (msg2qm) if possible without too much hassle.
 | 
						|
* Add new backend primax http://primax.sourceforge.net/ (won't be ever a
 | 
						|
  real sane backend)
 | 
						|
* qcam: Check file handling in /tmp.
 | 
						|
* 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?
 | 
						|
* Add installation procedure for translations of SANE backend's options.
 | 
						|
* check memory leaks (checked with purify and mtrace (from glibc)):
 | 
						|
* 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.->backend-writing.txt
 | 
						|
* Remove compiler warnings (>300 warnings even in disable-warnings mode,
 | 
						|
  >700 with --enable-warnings)) ->backend-writing.txt
 | 
						|
* Use #include "../include/sane/..." instead of #include <sane...>
 | 
						|
  ->backend-writing.txt
 | 
						|
* Use #include "../include/lalloca.h" instead of #include <lalloca.h>
 | 
						|
  ->backend-writing.txt
 | 
						|
* Update backend manpages (->backend-writing.txt).
 | 
						|
* Add description of --enable-parport-directio.
 | 
						|
* saned: Add documentation about the data connection.
 | 
						|
* UMAX Astra 1220U  backend
 | 
						|
  http://umax1220u-sane.sourceforge.net/
 | 
						|
* There seems to be yet another race condition or other source for
 | 
						|
  freezes in saned or net. Wheile scanning with pnm and auth, scanimage
 | 
						|
  freezes. Last message from saned: "process_request: got request 2".
 | 
						|
* Split configure option --enable-directio into --enable-scsi-directio and
 | 
						|
  --enable-parport-directio to avoid confusion. Also add appropriate
 | 
						|
  documentation.
 | 
						|
* sanei_usb: Add sanei_usb_control_msg. 
 | 
						|
* Add support for PV8630 USB chipset (as sanei interface):
 | 
						|
* Fix libsocket problem (OS/2). libsocket must be linked when testing for
 | 
						|
  libsyslog.
 | 
						|
* Add bearpaw backend (Mustek BearPaw 1200 + maybe 2400)
 | 
						|
  (will be supported by plustek backend)
 | 
						|
* Must -ldl be added to sane-config.in?
 | 
						|
* Use @LIBDIR@, @CONFIGDIR@ and the other @@ macros to refer to paths.
 | 
						|
  These are updated when installing to a non-standard prefix.
 | 
						|
* net: cancel doesn't work over the net at least with pnm and mustek.
 | 
						|
* add Jochen Eisinger's net.c and sanei_wire.c fixes/additions.
 | 
						|
* net.c: don't just ignore the byte-order for the image data (needed to
 | 
						|
  support depths > 8 bits/channel)
 | 
						|
* saned seems to have problems checking the peer name of incoming
 | 
						|
  connections. This happens at least with glibc 2.2.4 if the
 | 
						|
  name in saned.conf is not fully qualified. See sane-devel
 | 
						|
  "saned.conf hostname format".
 | 
						|
* If you mention sane-devel, also mention the website concerning
 | 
						|
  subscription (http://www.mostang.com/sane/mail.html), because you can't
 | 
						|
  write to sane-devel without subscribing.
 | 
						|
  Or use your own mail address in the manual page.
 | 
						|
* Check for logical errors and spelling
 | 
						|
* Check .desc files:
 | 
						|
* Check for formatting bugs in manual pages:
 | 
						|
* Use #include "../include/assert.h" instead of #include <assert.h> to
 | 
						|
  avoid problem with shared libraries on AIX.
 | 
						|
* scanimage: Maybe add ADF extensions from Caskey Dickson (or add them to 
 | 
						|
  scanadf if necessary).
 | 
						|
* Add Mustek USB backend (1200UB, 1200CU, 1200CU Plus)
 | 
						|
  http://www.meier-geinitz.de/sane/
 | 
						|
  Henning Meier-Geinitz <henning@meier-geinitz.de>
 | 
						|
* Add USB support for sane-find-scanner.
 | 
						|
* move .desc files for backends that are not included in SANE to
 | 
						|
  different directory (e.g. backends and external-backends)?
 | 
						|
* create sanei_usb.* (maybe containing access for libusb and direct access
 | 
						|
  for usb device files)? (sane-1.0.6)
 | 
						|
* Add sane-usb manpage
 | 
						|
* Check net/saned
 | 
						|
   - sometimes saned+net freezes right after a scan (is this still
 | 
						|
     occuring 2001-06-04?)
 | 
						|
* 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 -- I believe this is partly fixed
 | 
						|
  in tools/sane-config.in 2001-05-18]
 | 
						|
* Add links to sane(7) in all maual pages
 | 
						|
* Check AIX/gcc shared lib loading problem: When starting scanimage,
 | 
						|
    only dll is loaded.
 | 
						|
    Backend libraries can't be loaded:
 | 
						|
    [dll] load: dlopen() failed (Symbol resolution failed for
 | 
						|
       /tmp/sane-bin/lib/sane/libsane-umax.so.1 because:
 | 
						|
       Symbol __eprintf (number 55) is not exported from dependent
 | 
						|
       module scanimage.
 | 
						|
    This happens in most libraries. The reason is assert() e.g. in
 | 
						|
    sanei_scsci.c. As assert() is in libgcc.a it can't be linked at runtime.
 | 
						|
* Don't export any other symbols than sane_* and sanei_*
 | 
						|
* nec:
 | 
						|
   - Remove references to sharp backend (grep for "JX").
 | 
						|
   - Check for HAVE_SYS_SHM_H before including sys/shm.h and
 | 
						|
     disable shared memory support if necessary.
 | 
						|
* lines like "if (config_line[len - 1] == '\n')" can cause segfaults and
 | 
						|
  should be removed (removing "\n" is already done in sanei_config_read).
 | 
						|
  This ist just a fast grep. Check all 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
 | 
						|
* as6e: change :new status to :alpha, :beta, or :stable.
 | 
						|
* Check Tru64 Unix compilation problems with u_int* types. They are already
 | 
						|
  defined in sys/bitypes.h but this file isn't checked with AC_CHECK_TYPE.
 | 
						|
  (-> include sys/bitypes.h in these cases).
 | 
						|
* Fix HP-UX problems in isfdtype.c (and maybe others). sys/stat.h doesn't
 | 
						|
  seem to define stuct stat (not a bug, make was used instead of gmake).
 | 
						|
* Polaroid SprintScan 35 LE [should be included into microtek] 
 | 
						|
* Maybe add script to deinstall existing sane versions
 | 
						|
  - make uninstall
 | 
						|
  - install sane-uninstall script. Advantage: uninstall possible
 | 
						|
    without sourcecode (I think that's not necessary because you usually
 | 
						|
    have the sourcecode of a newer version if you want to uninstall. hmg)
 | 
						|
* 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 backend UMAX 1220P/2000P & HP 320C http://umax1220p.sourceforge.net
 | 
						|
* install all documentation that's available
 | 
						|
* Add a check for installed sane versions.
 | 
						|
  - Print a warning when already a sane version is installed
 | 
						|
  - If SANE is installed at a different location, ask user to
 | 
						|
    remove old installation first
 | 
						|
* epson: backend tries to detect usb scanners by default. This breaks with
 | 
						|
  non-epson scanners like the LM9831 bases Mustek Bearpaw 1200. The epson
 | 
						|
  backend freezes if such a scanner is plugged in. Try to make the test safe
 | 
						|
  or don't test without user interaction.
 | 
						|
* pnm: add more options for testing (e.g. arrays and read-only options)
 | 
						|
* sanei_scsi.c: OS/2: struct param breaks compilation with --enable-warnings.
 | 
						|
  (probably fixed by testing for os2.h in configure).
 | 
						|
* Check all manpages for references to find-scanner (->sane-find-scanner).
 | 
						|
* net.c doesn't compile on Irix because socklen_t isn't known
 | 
						|
* Add new backends: bh http://www.martoneconsulting.com/sane-bh.html
 | 
						|
* Add manpage for find-scanner.
 | 
						|
* Should find-scanner be installed?
 | 
						|
* net backend segfaults sometimes when connected to localhost. Enabling
 | 
						|
  debug output sometimes prevents segfaults. Cause of the problem:
 | 
						|
  Copying SANE_TYPE_STRINGs up to their maximum size in 
 | 
						|
  SANE_Option_Descriptor (strings may be shorter then size).
 | 
						|
* Compilation of most backends break with OS/2 and gcc because the
 | 
						|
  option -ansi doesn't seem to like sigset_t ?
 | 
						|
* Check for shm.h in configure
 | 
						|
* Add a global PATH_MAX macro somewhere (config.h ?) if it's not defined
 | 
						|
  by the system.
 | 
						|
* sanei_scsi.c: Add patch from FreeBSD ports (sanei_scsi_find_devices)
 | 
						|
  (after 1.0.4).
 | 
						|
* update libtool versioning system
 | 
						|
  - in /usr/local/lib/libsane.la "installed=no" is set, isn't 
 | 
						|
    "installed=yes" the correct entry?
 | 
						|
* plustek-share.h: remove //
 | 
						|
* as6e: Check result of stat for errors to avoid false recognitions of the
 | 
						|
  as6edriver.
 | 
						|
* artec: O_SYNC is not Posix. Breaks compilation on FreeBSD and (maybe) OS/2.
 | 
						|
* use strchr() instead of index() in mustek_pp to avoid problems when
 | 
						|
  icluding strings.h or string.h.
 | 
						|
* Add test for PTAL to acinclude.m4/configure.in
 | 
						|
* build on Irix fails because of problems with the jpeg library. If this
 | 
						|
  is removed in configure, build works. It complains about functions like
 | 
						|
  (typename) functionname (). It doesn't like the brackets which result
 | 
						|
  from expanding the macros EXTERN(x), METHODDEF(x), and GLOBAL(x) to
 | 
						|
  (x). Defining something like EXTERN(x) x seems to work.  Same for dc210.c
 | 
						|
  Something like --disable-jpeg for configure would be nice.
 | 
						|
* addition to hp backend (support for SCL-based HP OfficeJets)
 | 
						|
  http://hpoj.sourceforge.net
 | 
						|
* Libtool: 
 | 
						|
  - -version-info is used but with the current version number system 
 | 
						|
    -release should be used. (We should not change the version syntax
 | 
						|
     within an existing sane-standard, so we leave this)
 | 
						|
  - look for AIX problems (overwriting shared libs with eachother
 | 
						|
    because all libs are named libsane.so.1) (solved)
 | 
						|
  - look for Irix/cc problems (program searches for libsane.so.2 instead
 | 
						|
    of libsane.so.1). (Patch works for existing sane standard)
 | 
						|
* getopt.c and umax.c seem to use gettext? Can cause crash if frontends
 | 
						|
  are linked to libintl, too.
 | 
						|
* libdl is used in dll backend but -ldl is not added to LDFLAGS?
 | 
						|
* use strchr() instead of index() in sanei_auth, scanimage, saned
 | 
						|
  to avoid problems when icluding strings.h or string.h.
 | 
						|
* Remove frontends (at least xscanimage/xcam) from distribution. 
 | 
						|
* build on AIX does only work for static libraries. The shared libraries
 | 
						|
  seem to overwrite each other.
 | 
						|
* add sanei_authorize (function for all backends)
 | 
						|
* make authorization_callback work in net-backend and saned. Try to 
 | 
						|
  avoid plain text passwords?
 | 
						|
* Add as6e http://as6edriver.sourceforge.net/
 | 
						|
* stiff.c: Tiff header not written correctly: "Jaeger, Gerhard"
 | 
						|
  <gjaeger@sysgo.de> writes: When writing the TIFF header, you have to
 | 
						|
  specify the TAG "BitsPerSample", which tells a reader how many bits each
 | 
						|
  sample has. The current version only specifies one value (8 or 16). This
 | 
						|
  is wrong, as we have to specify one value for each channel (i.e for a
 | 
						|
  24bit RGB pic we must specify 8,8,8, see TIFF6.0 spec, [...]
 | 
						|
* don't install sanei_* headers
 | 
						|
* Add sane-pie (Pacific Image Electronics series of ScanAce SCSI scanners, and
 | 
						|
  the Devcom 9636/9630 BlackWidow) http://www.munton.demon.co.uk/sane
 | 
						|
* configure --without-x doesn't work (doesn't matter when frontends
 | 
						|
  are removed from package)
 | 
						|
* Create new package for frontends. 
 | 
						|
* 0 is white for sane in lineart and halftone, however, 0 is black for
 | 
						|
  the other modes. Possible reason: pnm data format. The SANE standard
 | 
						|
  doesn't talk about this (added point to SANE standard)
 | 
						|
* add ADF and TA entries to .desc files (not done, probably webpage gets 
 | 
						|
  too wide)
 | 
						|
* check DBG problems for non gcc compilers:
 | 
						|
  - no backend name output
 | 
						|
  - only global debug level
 | 
						|
* dll: make it robust against it being listed in the configuration
 | 
						|
  file (currently bad things will happen if dll attempts to load itself)
 | 
						|
* scanimage: add information about backend:devicename in the man
 | 
						|
  page and scanimage --help.
 | 
						|
* scanimage: check if devicename starts with a / and print a warning
 | 
						|
  message
 | 
						|
* scanimage: if no devices are detected print a message
 | 
						|
* use sanei_config_read() instead of fgets()
 | 
						|
* use #include "sane/..." instead of #include <sane/...>
 | 
						|
* Update LEVEL2 file. Ideas:
 | 
						|
* xscanimage: Fix "Gtk-CRITICAL **: file gtkmain.c: line 534 ..." bug
 | 
						|
  when no SANE devices found
 | 
						|
+ PREVIEW: maybe there should be an option to limit the preview
 | 
						|
  scan to the selected area? YES => this will also make it easier
 | 
						|
  to avoid the scan area selection to get confused when the user
 | 
						|
  resizes the preview area in a way that changes the aspect ratio;
 | 
						|
  in essence we want to allow for the preview-image to be a subregion
 | 
						|
  of the preview-window (done in xsane)
 | 
						|
+ xcam: allow disabling of advanced options and tooltips
 | 
						|
+ man page for xcam
 | 
						|
+ scanimage: support depths > 8 bits/channel
 | 
						|
+ upgrade to GTK 1.2 (but stay backwards compatible to 1.0 if possible)
 | 
						|
+ saned: check_host() consider using strncasecmp()
 | 
						|
+ GTK: changing the length unit causes dirty pixels in the unit-labels
 | 
						|
  of the "Geometry Group"
 | 
						|
+ preview: image data doesn't get preserved properly when changing
 | 
						|
  scan area size (reproducable by changing Mustek Scan source to TA)
 | 
						|
+ preview: when popping up the preview window, the current scan area is
 | 
						|
  not visible
 | 
						|
+ qcam: test b&w support (need volunteer!)
 | 
						|
+ hp: convert to use pixel-unit commands only; HP 5P doesn't support
 | 
						|
  decipoint commands
 | 
						|
+ mustek: the MFS-06000SP with firmware v3.12 does not seem to need any
 | 
						|
  line-distance correction at all!?!
 | 
						|
+ scanimage/xscanimage: when a scanner is busy while probing for devices,
 | 
						|
  the device is dropped silently from the list of available devices; this
 | 
						|
  is confusing particularly when remote controlling a device; it should
 | 
						|
  be possible to distinguish between a device that's busy and one that's
 | 
						|
  absent
 | 
						|
+ xscanimage: program crashes when preview window is popped down while
 | 
						|
  preview is being acquired!
 | 
						|
+ Mustek backend crashes when invoked via xscanimage through the network
 | 
						|
  backend.  It does not crash if there are no saved device settings.
 | 
						|
+ gtkglue: support vectors (requires a "graph" widget; see gimp/app/curves.c)
 | 
						|
+ xscan: make scrollbar wider
 | 
						|
+ xscan: at startup or after rebuilding the dialog, the notebook widget
 | 
						|
  displays both the standard and advanced options simultaneously
 | 
						|
+ xscan: pnm backend causes crash when hitting "Defaults" button
 | 
						|
+ scan: add three pass scanning support
 | 
						|
+ xscan: double-clicking selection should imply OK
 | 
						|
+ xscan: enabling the gtk_rc_parse() code causes segfault when scanning in
 | 
						|
  three-pass mode (pnm backend) => bug in gtkstyle.c (patch submitted)
 | 
						|
+ qcam: implement "christmas light" filter
 | 
						|
+ xscan/qcam: after scanning a preview, the original scan area seems to
 | 
						|
  get lost somehow => bug in restoring the scan area settings
 | 
						|
+ qcam: image always comes out black until the blacklevel has been modified;
 | 
						|
  why is this? => send dummy black-level after qc_reset()
 | 
						|
+ xscan: provide access option doc strings
 | 
						|
+ xscan: in GIMP mode, RED/GREEN/BLUE frames are not handled properly yet.
 | 
						|
+ preview: bit-depth is currently ignored (makes lineart etc fail)
 | 
						|
+ sanei: allow saving/restoring options on a per-device and per-user basis
 | 
						|
+ xcam: replace ugly top-left/bottom-right corner coordinates with something
 | 
						|
	more useful => they're advanced options now
 | 
						|
+ preview: modifying the scan area coordinates should update the selection
 | 
						|
+ preview: should we allow saving the current preview image? => yes
 | 
						|
+ xscan: make it possible to build with gtk alone (i.e., without gimp libs)
 | 
						|
+ xscan: use same scan-logic as preview (select-based, if possible);
 | 
						|
  should be able to share most of the code
 | 
						|
+ replace params.first_frame with params.last_frame---i don't know how to
 | 
						|
  use the former, the latter would be useful for xcam to implement support
 | 
						|
  for individual R/G/B frames
 | 
						|
+ saned: add multi-host capabilities (selection-phase ... how ??).
 | 
						|
+ saned: add authorization
 | 
						|
+ ensure frontend never link sanei_*() functions dynamically
 | 
						|
+ always define unique names in backends and define weak-aliases for
 | 
						|
  generic names where elf_alias is available---this should make it
 | 
						|
  easy to add "pre-load" support to dll.c (either for faster loading or
 | 
						|
  for systems that don't have dl*())
 | 
						|
+ make install: don't overwrite existing configuration files
 | 
						|
+ xcam: let user be able to type in a device string
 | 
						|
+ mustek: make sane_close() hang around until sane_cancel() has finished
 | 
						|
+ net: implement it: socket-based backend [Andy is working on this]
 | 
						|
+ need a camera front end (to allow recording video & audio)
 | 
						|
+ qcam: allow changing all parameters "on-the-fly" (while scanning)
 | 
						|
+ qcam backend: implement sane_set_io_mode() and sane_get_select_fd()
 | 
						|
+ make "scan" print current value of each option
 | 
						|
+ make "scan" apply any options before printing help message
 | 
						|
+ initialize backend debug level through environment variable (e.g.,
 | 
						|
  SANE_DEBUG_LEVEL)
 | 
						|
+ allow abbreviating string values and make them case-insensitive (as long
 | 
						|
  as they're unique) => see sanei_constrain_value()
 | 
						|
+ add support to "scan" for setting options to "automatic"
 | 
						|
+ update documentation and convert to latex & html
 | 
						|
+ add --width/--height support
 | 
						|
+ update Mustek backend with new notion of inactive options
 | 
						|
+ in verbose multibit mode print min/max graylevel value 
 | 
						|
+ Mustek segfaults after ctrl-C => need -Bsymbolic to ensure mustek backend's
 | 
						|
  references to sane_foo() get resolved within backend
 | 
						|
+ test parsing of boolean options
 | 
						|
+ --mode Gray causes segfault
 | 
						|
+ change scan to use getopt_long
 | 
						|
+ make Mustek backend work without having to first call get_devices()
 | 
						|
+ implement meta backend
 | 
						|
+ bring pnm backend up to speed
