TODO (2000-12-23)
|
|
|
|
******** todo ********
|
|
|
|
* add new frondends (?)
|
|
- scanadf
|
|
|
|
* 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. At
|
|
least the frontend shouldn't crash or produce invalid pnm files when
|
|
it gets a length of -1.
|
|
|
|
* 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)
|
|
|
|
* For 3-pass scanners, xscanimage doesn't update the scan progress
|
|
bar properly between scans; the scanner seems to be faster than
|
|
xscanimage can write to disk (problem: seek for every byte). This
|
|
doesn't happen as GIMP-plugin. It doesn't happen in blocking mode
|
|
either.
|
|
|
|
* 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?
|
|
|
|
* Test frontends on different os/platforms, fix possible compilation
|
|
problems
|
|
|
|
* Add/improve debug output for xscanimage and xcam.
|
|
|
|
|
|
******** done ********
|
|
|
|
* Adapt xscanimage to new GIMP API. Try to make it backwards compatible
|
|
with old GIMP versions if possible. Maybe two source/header files
|
|
for compatibility with old API?
|
|
* Add support for SANE_DEFAULT_DEVICE to xcam/xscanimage. Show the list
|
|
of devices with the SANE_DEFAULT_DEVICE preselected.
|
|
* use g_free for memory allocated by g_new.
|
|
* check configure.in/aclocal.m4: Compilation/link test for SANE doesn't
|
|
work.
|
|
* xscanimage doesn't exit when the window close button is pressed in the
|
|
"select device" window.
|
|
* configure --without-x doesn't work
|
|
* xscanimage prints warning if compiled with GIMP supports but run
|
|
standalone (at least with GIMP 1.1.29)
|
|
* 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, [...]
|
|
---> stiff.* files were removed from frontend package
|
|
* xcam: if the user quits xcam by the window manager, the process isn't
|
|
killed, only the window is closed
|
|
* Remove frontends (at least xscanimage/xcam) from distribution. Create
|
|
new package for frontends.
