backends
|
|
--------
|
|
* Add new backends (+ means: scheduled for version 1.0.9)
|
|
- hp4200 http://hp4200-backend.sourceforge.net/
|
|
+ Relisys Scorpio Super 3 - VM3575 (wip)
|
|
http://fz.eryx.net/sane/#teco2
|
|
- Genius Vivid Pro USB, Colorado USB 19200, Visioneer OneTouch 7600
|
|
IBM IdeaScan 2000 USB
|
|
http://homepages.paradise.net.nz/stevenel/scanner/
|
|
- Hewlett-Packard ScanJet 3300C / 3400C and 4300C (wip)
|
|
http://sourceforge.net/projects/hp3300backend
|
|
|
|
* 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.
|
|
|
|
* 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. Is this necessary? It seems to
|
|
work...
|
|
|
|
* dc210, dc240, gphoto2, and jpeg stuff: move sanei_* functions to sanei/
|
|
(if they are necessary). That's probably for SANE2.
|
|
|
|
* 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
|
|
- bh
|
|
- canon
|
|
- coolscan
|
|
- dmc
|
|
- qcam
|
|
- ricoh
|
|
- s9036
|
|
- sp15c
|
|
- tamarack
|
|
|
|
- etc?
|
|
|
|
* as6e: attach: memory (dev + dev-sane.name) isn't freed if driver isn't
|
|
found.
|
|
|
|
* net: add IPv6 support.
|
|
|
|
* Fix warnings about DBG calls (try gcc 3.x to get these warnings):
|
|
- umax1220u
|
|
|
|
* bh: Suspicious loop ("../../backend/bh.c", line 1923: warning:
|
|
end-of-loop code not reached), see sane-devel.
|
|
|
|
* coolscan: Lots of compilation warnings (e.g.
|
|
"../../backend/coolscan-scsidef.h", line 160: warning: initialization
|
|
type mismatch; empty declarations), see sane-devel.
|
|
|
|
* Check the return value of wait() and waitpid(). This is important, if
|
|
the status value is checked for e.g. WIFEXITED after the call of wait()
|
|
or waitpid(). Both functions may fail if the frontend already did a wait
|
|
for the children.
|
|
|
|
* remove ptal support from configure and hp backend
|
|
|
|
doc
|
|
---
|
|
* Add doxygen documentation for the remaining sanei files:
|
|
- sanei_pio.h
|
|
- sanei_pv8630.h
|
|
- sanei_wire.h
|
|
|
|
* sane.tex:
|
|
- Define the return values for sane_init? Define the consequences if
|
|
sane_init doesn't return SANE_STATUS_GOOD.
|
|
- Add a warning/explanation about problems with sane_get_select_fd, Unix
|
|
select() calls and sane_cancel.
|
|
- Add some text about the meaning of bits in 1-bit modes.
|
|
- Define, how to handle SANE_CAP_ADVANCED for groups.
|
|
|
|
* desc files:
|
|
- Don't use ":status :new"
|
|
- canon630u
|
|
- Make sure, that the manufacturer (and model) names use the same spelling:
|
|
- umax, plustek (Genius, KYE-Genius)
|
|
- plustek, umax_pp, avision, hp, hpsj5s (Hewlett-Packard instead of HP)
|
|
- Check URLs:
|
|
- dmc (dmc link)
|
|
- sm3600 (Add a slash after the microtek URL to avoid creating
|
|
duplicate links in the manufacturers listing)
|
|
- umax (http://www.heidelberg-cps.com/ , http://support.umax.com/ ,
|
|
http://www.umaxweb.com.tw/ )
|
|
|
|
- Mark scanners with ":status :untested" if they are untested by the author
|
|
or users:
|
|
- bh
|
|
- canon630u (add 636 as :untested (from manpage)?)
|
|
- coolscan2 (LS 4000 ED)
|
|
- plustek
|
|
|
|
- Remove unsupported scanners from the list or at least mark them with
|
|
":status :unsupported":
|
|
- mustek_pp
|
|
- plustek
|
|
- umax1220u
|
|
|
|
- Other problems/comments:
|
|
- bh (use backend comment instead of manufacturer comment, don't use
|
|
model name for comments or status indication)
|
|
- coolscan2 (LS-200 only mentioned in manpage?)
|
|
- umax1220u (status for Astra 2000U should be adjusted)
|
|
|
|
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.
|
|
- Add support for IP ranges in saned.conf (like 10.0.0.0/8)?
|
|
|
|
* scanimage: Check range of width and height. scanimage just uses the ranges
|
|
from br-x and br-y but this is wrong for tl-x and tl-y != 0 and for
|
|
SANE_UNIT_PIXEL.
|
|
|
|
sanei
|
|
-----
|
|
* sanei_scsi: Think about a completely 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.
|
|
|
|
* Check if the device file has the right type before accessing it. E.g.
|
|
check for major/minor numbers to avoid accessing a USB file as SCSI
|
|
device. This is finished for sanei_scsi.c/Linux and sane-find-scanner.
|
|
Patches for other platforms are welcome.
|
|
|
|
* sanei_scsi (Linux): Make sure that the SCSI driver is loaded when
|
|
checking for scanners. Ideas: Open/close all the /dev/sg* files in
|
|
sanei_scsi.c, dll.c or in a new backend.
|
|
|
|
platform-specific
|
|
-----------------
|
|
* 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).
|
|
|
|
* Add support for Mac OS X in sanei_scsi.c.
|
|
|
|
* Find out why USB on *BSD only works once (at least for Mustek scanners
|
|
and OHCI).
|
|
|
|
misc
|
|
----
|
|
* sane-config: add options "--exec-prefix=...." and "--prefix=..."
|
|
compareable to gtk-config
|
|
|
|
* Make output of sane-find-scanner more flexible. See scanimage -f for
|
|
details.
|
|
|
|
* Check licence issues with getopt*.c and md5.c. These files are GPLed, so
|
|
if they are used in backends, their SANE exception will be void.
|
|
|
|
* Can we link external libraries only to backends that need them?
|
|
See http://fz.eryx.net/sane/#configure.
|
|
|
|
* Fix japi to run on current jdks. Swing is now included, and there is
|
|
a segfault in Sane.c.
|
|
|
|
******** done ********
|
|
* Fix inclusion of saneopts.??.po in po/. Currently, the "" header is
|
|
defined twice.
|
|
* Don't use "echo -e" in shell scripts. That's not supported by the original
|
|
sh (-->sane-config.in).
|
|
* scanimage: Add i18n (NLS) support? We don't do it (too much trouble with
|
|
options and UTF8 support).
|
|
* Desc files: Don't use :interface if you don't have a hardware device
|
|
* Use DBG(...) instead of fprintf(stderr, ...) or printf
|
|
* OS/2 needs a "# define strncasecmp(a, b, c) strnicmp(a, b, c)" in config.h.
|
|
* sanei_usb.c: Can libusb be used alternatively to the kernel scanner
|
|
drivers?
|
|
* sane-backends.html should be sorted by manufacturer, not by backend.
|
|
* Add support to sane-find-scanner to check whole directories for device
|
|
files. E.g. /dev/scsi/scanner and /dev/scsi/processor for Solaris.
|
|
* 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.
|
|
* Check include/sane/config.h.in for unnecessary macros.
|
|
* scanimage: Fix pnm 16 bit output (partly patch available).
|
|
* Make all symbols that don't start with sane_ or sanei_ static (see
|
|
make libcheck):
|
|
* avision: line 1393: word isn't freed sometimes (maybe if cp == line?)
|
|
* dll: Check what happens when calling sane_init/sane_open and sane_exit
|
|
more than once.
|
|
* Update backends
|
|
+ Canon FB620S flatbed scanner and FS2710 film scanner support
|
|
(update for canon backend).
|
|
ftp://stthd0.pc.uni-koeln.de/pub/canon-1.08.tar.gz
|
|
Ulrich Deiters <ukd@xenon.pc.Uni-Koeln.DE>
|
|
* The plustek backend doesn't compile on OS/2 because
|
|
in plustek-usbhw.c itimerval is unknown.
|
|
* Add backends:
|
|
+ Fujitsu M3091DCd support
|
|
Done (fujitsu).
|
|
* Add backends (no response from author and unchanged for some time)

|
|
- v4l2 http://video.inodes.org/sane-v4l2/
|
|
* Fix shared lib problem with NetBSD. Starting scanimage results in:
|
|
"Cannot open "../backend/.libs/libsane.so". However, scanadf works.
|
|
* Check if a new version of libtool can fix the above mentioned issues.
|
|
Currently (2002-03-17) the CVS version of libtool works on NetBSD but
|
|
breaks AIX-4.
|
|
* Combine all the Fujitsu backends into one single backend
|
|
* sane-backends.html should state more clearly which backends are included
|
|
in the distribution. Solution: Split into two lists.
|
|
* Keep config.guess and config.sub up-to-date.
|
|
* sane.tex: Add new sane.type = "film scanner". Check the other well known
|
|
strings for completeness.
|
|
* make distclean should remove *.orig, *.old, .#*, *.tar.gz, and similar
|
|
files.
|
|
* Shared libs work with OpenBSD. However, they are named libsane.so.1.6
|
|
instead of 1.0.6. Is this correct?
|
|
* #include "../include/sane/config.h" should be the first include in every
|
|
file (see doc/sane-backend-writing.txt for the lalloca exception):
|
|
* Don't use -ansi for HPUX (see sane-devel).
|
|
* 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
