backends
|

--------
|
||||
* add new backends (?)
|

- as6e http://as6edriver.sourceforge.net/
|

- bh http://www.martoneconsulting.com/sane-bh.html
|

- Polaroid SprintScan 35 LE [should be included into microtek]

|
||||
- primax http://primax.sourceforge.net/
|
||||
- hp4200 http://hp4200-backend.sourceforge.net/
|
||||
|
||||
* use DBG(...) instead of fprintf(stderr, ...)
|
||||
- hp
|
||||
- microtek
|
||||
- microtek2
|
||||
|
||||
* use sanei_config_read() instead of fgets()
|
||||
- umax (will be fixed with the next backend release)
|
||||
|
||||
* use #include "sane/..." instead of #include <sane/...>
|
||||
- umax (see above)
|
||||
|
||||
* check #include <lalloca.h> (is this a global system header
|
||||
on any platform? Otherwise --> "lalloca.h")
|
||||
|
||||
* make authorization_callback work in net-backend and saned
|
||||
|
||||
* check net/saned
|
||||
- net backend segfaults if saned isn't started
|
||||
- don't just ignore the byte-order for the image data (needed to
|
||||
support depths > 8 bits/channel)
|

- mustek: for 3-pass scanners, it is said that xscanimage doesn't update

|

* mustek: for 3-pass scanners, it is said that xscanimage doesn't update
|
||||
the scan progress bar properly between scans; it is said to stop at
|
||||
90%, start the next pass, and once the next pass has started, it moves
|
||||
on to 100% and the progress bar disappears at that point
|
||||
- man pages for the API functions
|
||||
- xscanimage: provide both scale and textentry for ranges (make new widget)
|
||||
- xcam: provide access to option doc strings
|
||||
- xscanimage: scanning of images whose heights is not known a priori is not
|
||||
supported yet; this is going to be important for handheld scanners
|

|

* 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
|

|
||||
---
|
||||
* add sane manpage
|
||||
- versioning system
|
||||
- SANE API
|
||||
|
||||
* add sane-usb manpage
|
||||
|
||||
* Documentation for sanei API
|
||||
- any ideas for this?
|
||||
|
||||
frontends
|
||||
---------
|
||||
* Remove frontends (at least xscanimage/xcam) from distribution. Create
|
||||
new package for frontends.
|
||||
|
||||
* add new frondends (possibly to frontend package) (?)
|
||||
- xsane
|
||||
- scanadf
|
||||
|
||||
* use #include "sane/..." instead of #include <sane/...>
|
||||
- umax
|
||||
|
||||
* add possibility to use external filters to xscanimage/xsane (?)
|
||||
|
||||
* xscanimage/xcam: support depths > 8 bits/channel
|
||||
|
||||
* xscanimage: provide both scale and textentry for ranges (make new widget)
|
||||
|
||||
* xcam: provide access to option doc strings
|
||||
|
||||
* xscanimage: scanning of images whose heights is not known a priori is not
|
||||
supported yet; this is going to be important for handheld scanners
|
||||
|
||||
* xcam: add dithering and support for SANE depths other than 8 bit (test
|
||||
with Mustek backend, for example)
|
||||
- xcam: add recording feature (e.g., GIF, JPG, or MPEG)
|
||||
- dll: make it robust against against it being listed in the configuration

sanei
|
||||
-----
|
||||
* don't install sanei_* headers (?)
|
||||
|
||||
* add sanei_authorize (function for all backends)
|
||||
|
||||
misc
|
||||
----
|
||||
* update libtool versioning system
|
||||
- -version-info is used but with the current version number system
|
||||
-release should be used.
|
||||
- look for AIX problems (overwriting shared libs with eachother
|
||||
because all libs are named libsane.so.1)
|
||||
- look for Irix/cc problems (program searches for libsane.so.2 instead
|
||||
of libsane.so.1). This was fixed by a "bad hack" which should be
|
||||
reverted .
|
||||
|
||||
* check DBG problems for non gcc compilers:
|
||||
- no backend name output
|
||||
- only global debug level
|
||||
|
||||
* remove compiler warnings (>400 warnings even in disable-warning mode!)
|
||||
|
||||
* Update LEVEL2 file. Ideas:
|
||||
- add support for buttons etc. on the scanner/camera
|
||||
- Change of the version number system (the current standard version
|
||||
system is not really used in the SANE distribution).
|
||||
- add more frame types
|
||||
- add alpha channel so that RGBI scanners like Nikon LS-20 can
|
||||
send infra-red info back to gimp for post-processing
|
||||
- Might be nice if arbitrarily defined multiple channels, were possible.
|
||||
Some way of indicating the number of channels possible, and some
|
||||
details (wavelength, bandwidth, ...)
|
||||
- (see sane-devel archive for more ideas)
|
||||
|
||||
* 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
|
||||
(not possible if I'm not root on the system)
|
||||
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
|
||||
|
||||
* add ADF and TA entries to .desc files
|
||||
|
||||
* add alpha channel so that RGBI scanners like Nikon LS-20 can
|
||||
send infra-red info back to gimp for post-processing
|
||||
|
||||
|
||||
******** done ********
|
||||
|
||||
+ PREVIEW: maybe there should be an option to limit the preview
|
||||
scan to the selected area? YES => this will also make it easier
