### Miscellaneous
- `udev` rules now trigger on all events other than `remove` (!541).
This aims to address a kernel API change introduced in 4.14. The
new behaviour may slow down `udev`'s processing of kernel events
when still using our plain `udev` or `udev+acl` rules, even though
these have been optimized slightly (#341). If that bothers you, now
is a good time to switch to our `udev+hwdb` rules in combination
with the `hwdb` database if you have not done so already.

- `saned` now cancels scans if the data connections appears to have
gone away (after 4 seconds by default, configurable in `saned.conf`)
- adds `--output-file` option to `scanimage`
- adds `--help` option to `scan-find-scanner`
- changes `sane-desc` to create relative hyperlinks
### Documentation
- adds translations for Catalan, Hebrew and Valencian
- updates translations for British English, Dutch, German and
Ukrainian
- marks unmaintained backends as such
- documents USB workaround in `sane-usb` manual page
### Build
- requires a C++11 compatible compiler for the `genesys` backend
- requires a JPEG library when building the `pixma` backend
- fixes unneeded linking when not using preloadable backend support
- disables pthread support for systems with non-integral `pthread_t`
type
- fixes USB support detection on BeOS and OS/2 at `./configure` time
- normalizes trailing whitespace in source code files. If you have
local patches that no longer apply, have a look at the whitespace
ignoring options of `patch` and `git apply`.
New with 1.0.27 (see Note 1), released 2017-05-22:
* Significant enhancements to canon_dr, epjitsu, epsonds, fujitsu,
genesys, hp3500, pixma and xerox-mfp backends.
* Minor updates, bugfixes or scanners added in several backends.
* 30+ new scanner models supported.
* Made libusb-1.0 the default for USB support (see Note 2).
* Switched code from C90 to C99 (Thanks to Volker Diels-Grabsch).
* Updated Linux USB3 workaround (see Note 3).
* Documentation and translation updates.
* Bugfixes (Avahi, threading, USB, ICC/PNG/JPEG, etc).
* Reduced compiler warnings, improved code (see Note 4).
Note 1: There is no 1.0.26 release of sane-backends. That number was
skipped so that our development version numbers would more clearly be
an extension of the prior release. This should make packaging a little
easier for our downstream users.
Note 2: On all systems, the --enable-libusb* flags are now ignored.
Instead, the --with-usb and --without-usb flags now control support.
When neither is given, USB support will be enabled if possible and
disabled otherwise. If --with-usb is requested but not possible,
./configure will fail. There is no support to prefer libusb-0.1 over
libusb-1.0. When libusb-1.0 is not found, libusb-0.1 will be tried.
Note 3: The Linux USB3 workaround which was added in version 1.0.25 is
now disabled by default. If you have difficulty using a scanner which
previously worked, or intermittent scanner availability, try setting
the new environment variable SANE_USB_WORKAROUND=1 before starting
your frontend.
Note 4: A special thanks goes to Olaf Meeuwissen for picking up the
janitorial duties in sane-backends. He has found and fixed a large
number of long-standing bugs, curated our bug tracker, improved our
build scripts and docs, and provided user support. Thank you Olaf!

New with 1.01:
* Miscellaneous
o configure --disable-shared works again
o scanimage -T testing option added (by Nick Lamb)
o in dll.conf, the pnm, dc25, and dc210 backends are now disabled
(commented out) by default. The net backend is now enabled by
default. The pnm backend has been disabled as it often proved
confusing to novice users. The dc25 and dc210 backends were
disabled because they initialize very slowly if no camera is
attached.
o Downgraded PNM backend to the version shipped with SANE 0.74.
The scan area options as implemented in SANE 1.00 were
incorrectly implemented which made the backend unreliable.
* New tool to turn off Mustek 600 II N scanner (by Andreas Czechanowski)
o the new binary tools/mustk600iin-off allows to turn off a
Mustek 600 II N scanner (note: you'll need to install this tool
manually if you want it)
* New backend for Sharp scanners (by FUKUDA Kazuya & Abel Deuring)
o supports the Sharp JX-610, JX-250, and JX-330 SCSI scanner
o preview/lineart/haftone/threshold are untested
* Updated Kodak DC25 backend (by Peter Fales).
* Updated HP backend (by Peter Kirchgessner)
o New features:
- Option 'unload after scan' for PhotoScanner
- Manual page sane-hp updated
- hp.desc updated
o Bugfixes:
- Adjustable scan size for scan from ADF
- No blanks in command line options
- Segmentation fault for starting scanimage -d hp:/dev/sg0
without /dev/sgo in hp.conf
Scanning from the ADF therefore should work now.
* Updated Microtek backend (by Matto Marjanovic)
o Fixed off-by-1 error in revision-number parsing.
o dump_inquiry() now prints the "Vendor Specific String".
o Added model code/vendor name for the other 600ZS.
o Made get_scan_status() retry delay increase with each try (will
this help the poor 600ZS?).
o Corrected base resolution for Agfa StudioScan II/IIsi (400dpi).
o Disabled backend's clever aspect-ratio correction code for
expanded-mode scans with StudioScan II/IIsi (scanner handles it
internally - smart scanner.)
o Fixed gamma LUT code parsing stupidity: now correctly
determines maximum allowed LUT size, and uses it. (Especially
necessary for StudioScan II/IIsi.)
o The E6 claims to only support 256-byte LUT's, but the backend
now ignores that misinformation (and uses 1024).
o Now ignores denial of expanded-mode by older E6's (model code
0x63), in addition to newer E6's.
* Updated Microtek2 backend (by Bernd Schroeder)
o Added support for non-blocking I/O.
o Preliminary support for a strip and a slide mode.
o For people, who are annoyed, if the the scanhead moves back and fourth
during a scan (backtracking): There is a new option 'disable
backtracking'. At present this option must be activated by
uncommenting the respective entry in the included microtek2.conf
file. This is an advanced option.
o The X6EL should no longer produce pixel junk after one successful scan.
* Updated Mustek backend (by Andreas Bolsch)
o larger buffer acquired (speeds up scanning slightly)
o for SE models minimal resolution increased from 60 dpi to 75 dpi
o for SE models 75 dpi in color mode is no longer used as the newer
firmware version seems to be even more buggy
o bug in calculation of gamma table corrected (applies only to SE models,
NOT related to the overflow problem which was corrected via CLIP( ) )
o default resolution is now set according to the minimal resolution
(firmware dependent)
o for SE models all unsupported options (speed, ... ) explicitly disabled
* Updated Nikon Coolscan backend (by Didier Carlier)
o Reverse the pixel order for the LS-1000.
* Updated snapscan backend to v0.6 (by Kevin Charter and Petter Reinholdtsen)
o Fixes the versioning problem.
o Add support for SnapScan 1236s (should also work for SnapScan 600).
* Updated UMAX backend (by Oliver Rauch)
o Added support for Linotype Hell Saphir 2
o Changed bug in gray gamma data conversion
o Added support for Nikon AX-210
o Added "Vista S-6E" as supported
o Added PowerLook-II (PL-II) as supported
o Added Astra 600S as supported
New with 1.00:
* Upgraded to libtool-1.2.

Supports:
o AGFA Focus GS (6 bit gray scale) (untested)
o AGFA Focus Lineart (lineart) (untested)
o AGFA Focus II (8 bit gray scale) (untested)
o Siemens S9036 (8 bit gray scale) (untested)
o AGFA Focus Color (24 bit color 3-pass)
o AGFA Focus Color Plus (24 bit color 3-pass)
* New Kodak DC210 still camera backend (by Brian J. Murrell)
* New Ricoh backend (by Feico Dillema).
* New HP backend.
The backend formerly known as "xhp" is now the default HP backend.
This backend should support HP scanners much better and was
contributed by Geoffrey Dairiki and Peter Kirchgessner.
- Added support for HP 6200C
- Suppress halftone mode on photosmart (it is not supported)
- Show calibrate button on photoscanner only for print media
- Add media selection for photoscanner
- Cleanup hp_scsi_s structure
* Updated apple backend (by Milon Firikis).
Now you should be able to scan from ColorOneScanners (in non color
modes) and maybe from OneScanners (untested).
* Updated Artec backend (by Chris Pinkham).
* Updated Kodak DC25 backend (by Peter Fales).
* Updated Microtek backend (by Matto Marjanovic).
- Fix segfault on exit due to unnecessary free() in sane_close().
- Fix to red channel shift bug (which crept in during rewrite of
color-handling code).
- Addition of "patch level" to version codes.
* Updated Microtek2 backend
- Added support for ScanMaker 330, ScanMaker 636, ScanMaker E3plus,
ScanMaker X6 and Phantom 636.
- Other improvements (this includes support for automatic document feeders
and transparency adapters, missing option descriptions were added).
- Updated the manual page.
* Updated Mustek backend (patches by Andreas Bolsch and Heiko Schroeder)
- Heiko's patch should make resolutions >300dpi work for MFS-6000CX.
Andreas's patches:
- Should work with ScanExpress 6000SP, 12000SP as well as older models
- Bug with MFS-12000SP corrected (poined out by Daniel Deckers)
- Bug which caused xscanimage to crash after color preview corrected
- Improvement(?) in high resolution
Important Notes for ScanExpress models:
- Resolutions below 60 dpi don't work (firmware problem).
- Resolutions >300 dpi (6000 SP) or >600 dpi (12000 SP) result in
different x/y-resolution as 6000 SP and 12000 SP have in fact only
300 dpi and 600 dpi CCD sensors, respectively.
- Resolutions >300dpi in color mode sometimes result in corrupted images
(parts duplicated/shifted *HORIZONTALLY*) depending on hardware
configuration. Killing all other applications and disabling swap
(if sufficient physical memory available) may help.
I added some code which writes to every page of the buffer prior
to scanning to fool the memory management and scanned a full page
color scan with 600dpi * 1200dpi. Very slow but image seemed ok
after pnmscale.
- Max. scan area: 0-216mm (hor.), 2.5-294.5mm (ver.)
The scanners can't scan the first 2.5mm (ver.), so you *MUST*
specify the scan area according to this restriction!
- The scanners support only lineart (1 bpp), gray (8 bpp), color (24 bpp).
Although the scanners have 10 bit (6000 SP) or 12 bit (12000 SP)
A/D-converters, they can send only 8 bit values to the host.
The higher resolution may only be used via gamma table.
- For compatibility only 256 entry gamma tables may be specified, the
actual gamma table sent to the scanner is linearly interpolated from it.
- In lineart mode only brightness may be adjusted.
- Cover open/closed reported only via debug output and ignored otherwise.
- Use of SCSI card supplied with scanner is *NOT* recommended. (Don't
forget termination!)
* Updated UMAX backend (by Oliver Rauch)
- added output of umax-backend-version in sane_init
- added Linotype Hell Jade2 (Vobis ScanBoostar Premium)
SCSI-ID "LinoHell","Office2" as supported scanner
- changed base of calculation of scanwidth and scanlegth from
pixel to resolutionbase (1/300, 1/600 or 1/1200 inch)
- changed calculation for width in pixels for lineart mode
- changed selection for calibration mode
- added inquiry for UMUX UC1200SE
- corrected 12/36-bit-mode in send_gamma_data and array in umax.h
* Updated SnapScan backend to v0.5 (by Kevin Charter)
- bug fixes (Wolfgang, David)
- addition of threshold control for lineart mode (Mikko)
- Vuego 310S support (Wolfgang)
- default scan area now maximal (Kevin)
New with 0.74:
* GIMP auto-detection should work again.
* Service name for remote scanning changed from "saned" to "sane".
Be sure to update your /etc/services and /etc/inetd.conf if you
use remote scanning! We generally try to avoid such incompatible
changes, but the name "saned" was definitely wrong, so it seemed
better to change it now.
* Thanks to Matto Marjanovic work, each backend now comes with a
.desc file that describes exactly what devices it supports. These
description files can be automatically translated into various
other formats, such as HTML. See:
http://www.mostang.com/sane/sane-backends.html
for an example as to what this can do for you.
* New backend for Kodak DC25 digital cameras (by Peter Fales).
* Updated Artec backend (by Chris Pinkham).
* Updated Microtek backend (by Matthew Marjanovic)
o Complete rewrite of bit-shuffling, buffering, and color-handling code.
o Improved rescaling algorithm for expanded resolution scans.
o Support for 600GS (and maybe ZS, too) (thanks to Oliver Neukum).
o Support for document autofeeder and IIG (thanks to Ross Crawford).
o Fixed sane_cancel.
o sane_get_parameters size estimates are now accurate to the last bit.
o get_scan_status timeout increased (for 600GS), status code fixed.
o Fixed parsing of 3-pass bit in INQUIRY data.
o Stopped sending gamma tables to scanners that don't want them.
o Made precalibration a bit more robust (always attempt at least one
scan line now).
o Much, much code clean-up.
o Tested & working with saned. (Atrocious hack so sane_read
handles buffers smaller than one scanline.)
o Auto-expand pre/post hold buffers as necessary (fixes some problems
with single-pass color scans).
o Added configuration file option to disable precalibration logic.
o Fixed document size calculations.
o Added more informative scsi-II note.
o Remove misnomer "Highscan" from manpage.
o Updated man-page.
* Updated Microtek2 backend (by Bernd Schroeder)
o changed the code for gamma calculation and added a custom gamma table
to the options. In some cases this requires an additional memcpy(),
but the code is now leaner and cleaner.
o fixed the bugs that the backend didn't compile with non gcc compilers.
o added an option to control exposure times.
o rewrote the code that processes the data that is received from the
scanner and transfers it into the frontend buffer. The smallest unit of
data that can be copied into the frontend buffer is now a pixel, no
longer a complete line.
o added (a yet) undocumented option "strip-height" that allows to control
the number of lines that is read from the scanner with one "read image".
o fixed a bug that caused scanimage to sigsegv when calling sane_exit()
without having written all data into the output file.
o added code to support scanners with more than 8 bit output per color.
Due to the lack of such a scanner this functionality is COMPLETELY UNTESTED
and there are some potential sources of bugs, but at least one could give
it try.
o added sanei_config_attach_matching_devices()
o improved the code for the check if it really is Microtek SCSI-II scanner
o fixed the "lineart inverted" bug
o The threshold option in lineart mode is now in the enhancement group
o changed the default for the resolution
o The values for the SANE_Params struct are calculated more precisely
o dito the number of scan lines that fit into the frontend buffer
o changed some return statuses ( replaced SANE_STATUS_INVAL with
SANE_STATUS_IO_ERROR where the first one is not allowed)
o completely rewrote the end of scan and cancel scan handling
o fixed another bug that caused xscanimage to crash with sigsegv
under some circumstances (check of the inquiry result was wrong)
o added model code for a Vobis Highscan
o support for new format of configuration file (including
"option <opt> <val>")
* Updated Nikon Coolscan backend (by Didier Carlier).
* Updated UMAX backend (by Oliver Rauch):
o Cancelling a scan now works, cancelling a preview still makes problems!
o Preview fix is activated for Astra 600S, Astra 610S and Vista S6E
scanners. (calibration by driver still does not work for these scanners).
- removed button for preview patch
o Quality calibration / calibration by driver now works for same scanners.
- added selection for type of shading data calculation
o Solved problem with black area at top of the image
(happened only with some SCSI-adapters).
o Added gamma download format type 0 and type 1 for older scanners.
o Added Astra 1220S as supported scanner:
- added 36 gamma input bits support for Astra 1220S
- added 36 output bits support, but there is no frontend that can
handle it!
o Added inquiry for Escom Image Scanner 256 (UMAX UG80).
* OS/2 (by Yuri Dario):
o Updated SCSI support so sanei_scsi_find_devices is supported now.
o Epson parallel support added (by Rocco Caputo <troc@netrus.net>)
New with 0.73:
* In xscanimage, the selection box now gets updated again when changing
the geometry option sliders---really!
* On Linux, it is now possible to specify SCSI device names by entering
their SCSI ids. For example, instead of "/dev/scanner", one can now
specify "scsi MUSTEK" to get all scanners manufactured by Mustek. This
feature is currently supported by the all SCSI backends except
microtek2. This feature is courtesy of Oliver Rauch.
* Backend libraries are now installed in $(libdir)/sane (/usr/local/lib/sane/,
by default).
* Updated Microtek backend (Matto Marjanovic):
- ScanMaker 600ZS, Agfa Arcus II, StudioScan, and StudioScan II
now supported (or recognized, at least ;-).
- Fixed 3-pass scanning.
- Various bug-fixes (see ChangeLog for details).
* New Microtek2 backend (Bernd Schroeder)
This backend supports the ScanMaker 630 and possibly other newer scanners
that are not supported by the "old" Microtek backend.
Additional info by Bernd:
This is the very first release of this backend, so consider this
software to be in alpha state. The backend was developed on a Pentium
(60 Mhz) with Linux 2.0.29 and a ScanMaker 630 attached to the
Adaptec AHA1505E that shipped with the scanner. As frontend
xscanimage was used. It is intended to work with other models, too,
but there are no experiences yet.
The following options are supported:
- 8-bit color, 8-bit grayscale, halftone and lineart scans.
- brightness, contrast, shadow, midtone and highlight control
- scalar gamma correction.
Options that are not yet supported include:
- 3-pass scanners
- more than 8 bit per color output data. Provisions are made here
and there in the code, to support more than 8 bit, but that's
incomplete.
* configure --disable-static should now work as expected.
New with 0.72:
* New backend for Artec scanners.
This backend is known to work with Artec AT3, but others may work
too (A6000C should work).
* Updated DMC and Microtek backend.
* Updated UMAX backend:
** added exposure time adjustment (for high-end scanners)
** added lamp density control (for high-end scanners)
** UMAX Astra 6X0S works in color-mode now, you have to enable
preview_patch!
** added support for UMAX UC1200S and UC1260, but it will not work fine!
** enabled x-resolution greater than 600 dpi if supported by scanner
(e.g. UMAX S12) but it sometimes still does not work right!
* Updated SnapScan backend:
There is now support for the SnapScan 310 and 600 scanner models.
* OS/2 and FreeBSD support should be working again.
* New backend writer's guide to SANE
File backend/GUIDE outlines a few rules that should help in writing
a new backend.
New with 0.71:
* Polaroid Digital Microscope Camera (DMC) backend
Written by Dianne Skoll <dianne@skoll.ca>
* Apple scanner backend
Written by Milon Firikis <milonf@isosun.ariadne-t.gr>. This backend
supports AppleScanner and has preliminary support for OneScanner and
ColorOneScanner.
* Nikon CoolScan backend
Written by Didier Carlier <didier@sema.be>.
* Apollo Domain/OS support
Contributed by Paul Walker <paul@uugw.hifn.com>.
New with 0.70:
* Preliminary version of AGFA SnapScan backend is now included.
This backend is know to work with AGFA SnapScan scanners but
is unlikely to work with any other AGFA
See scanner.http://www.cs.ualberta.ca/~charter/snapscan.html
for details.
* Various minor bug fixes that prevented SANE from building on
non-Linux platforms.
* xscanimage now honors WM_DELETE message.
* Updated UMAX backend.
New between 0.6 and 0.69:
* Mustek backend now supports the Transparency Adapter on the Paragon 1200SP
(MFS-12000SP).
* New backend for Canon scanners.
This backend was written by Helmut Koeberle <helmut.koeberle@bytec.de>.
It is known to work with the CanonScan 600 though not all features
are supported yet.
* Solaris SCSI support now exists.
Thanks to Martin Huber <hu@garfield.m.isar.de>, the SCSI backends are
now usable under Solaris, too. See README.solaris for details.
* AIX SCSI support now exists.
Thanks to Fred Hucht & Michael Staats, the SCSI backends are now usable
under AIX, too.
* New backend for Tamarack and ESCOM scanners.
This backend was written by Roger Wolff <R.E.Wolff@BitWizard.nl> of
BitWizard.
* New backend for Siemens S9036 scanner.
This backend was written by Ingo Schneider
<schneidi@informatik.tu-muenchen.de>.
* find-scanner (by Oliver Rauch)
SANE now comes with a program called find-scanner (in the tools
subdirectory) that can be used to find the device name of attaches
SCSI scanners.
Note that this program is not normally installed as part of the
normal SANE installation as this program is not something an
end-user should ever have to use.
* The Mustek backend has preliminary support for the Paragon 600 II N
scanner. This scanner attaches directly to a Mustek-supplied
ISA card which implements a funky parallel port. For details, see
the section entitled PARALLEL PORT SCANNERS in sane-mustek(5).
Use at your own risk!
* The location of the configuration files can now be overridden with
environment variable SANE_CONFIG_DIR (see also man-pages for the
backends and programs).
* When preloading backends into dll, they now appear in the same order
as if they had been loaded dynamically (i.e., in reverse order in
which they're listed in dll.conf).
* Java frontend (by Jeff Freedman)
SANE now includes a Java frontend for SANE. However, the Java files
are not built by default. See japi/README.JAVA for details.
* There is a Java API for SANE now. See japi/README.JAVA for details.
This code is courtesy of Jeff Freedman <jsf@hevanet.com>.
* UMAX updates (by Oliver Rauch):
- the umax backend is now fully runtime configuable---there are no
longer any build-time configuration options.
- Umax T630, Astra 610S, and Linotype Hell Office scanners are now
supported
- gamma-data now works on Astra 1200 S with 30 bits/pixel
Note: None of the SANE frontends presently support 30 bits/pixel.
If you're interested in fixing this, send mail to
sane-devel@mostang.com.
* The Mustek backend is now fully runtime configurable---there are no
longer any build-time configuration options. To this end, the
mustek.conf configuration file now supports options linedistance-fix,
lineart-fix, and strip-height (see sane-mustek(5) for details).
* New backend for Epson scanners
An alpha-quality backend for Epson scanners is now included with SANE
thanks to the efforts of Kazuhiro Sasayama <kaz@hypercore.co.jp>.
* OS/2 Support
Thanks to Jeff Freedman <jsf@hevanet.com> SANE now supports OS/2.
* New backend for Microtek scanners
Thanks to the excellent work of Matthew Marjanovic <maddog@mir.com>,
the Microtek is now taking shape.
* Irix SCSI support
Thanks to the work of Michael Sweet <mike@easysw.com>, there is now
SCSI support for Irix!
* Improvements to the UMAX backend (by Oliver Rauch):
** workaround for preview-bit-problem in RGB-mode (UMAX S6E ...)
** unsupported options are disabled
** now three_pass_scan should work
** new supported scanners:
*** UC840
*** Astra 1200S
* The Mustek configuration file (mustek.conf) now supports a configuration
option to limit the height of the strip that is scanned with a single
SCSI read command. The syntax is:
option strip-height HEIGHT
where HEIGHT is a floating point number that gives the maximum strip height
in inches. This option should be set to a small value (e.g., 1
inch) when the scanner is connected to a SCSI bus shared with other devices
or when using a broken SCSI driver whose timeouts expire prematurely. For
best scan performance, the strip-height should be set to a large value or
the option should be removed completely. See the sane-scsi(5) man-page for
details on how drivers with premature timeouts can be fixed (the Linux
ncr810 driver is the only known driver with this problem at this point).
* The preview window now properly draws the initial window-selection.
* Mustek backend now uses a SCSI command queue to avoid performance
problems with three pass scanners. This can reduce scantimes from
15 minutes down to 3 minutes!
* Mustek backend will now wait for up to 1 minute for a scanner to
become ready if the scanner name is specified explicitly. E.g.,
"scanimage -d mustek" will timeout almost right away (since the
Mustek device name is not specified explicitly) whereas
"scanimage -d mustek:/dev/scanner" will wait for up to a minute.
* HP backend now uses pixel-unit commands to accommodate ScanJet 5P.
* Platform-specific SCSI setup info is now in sanei-scsi(5).
* xscanimage(1) now has a section on how to run it under GIMP.
* B&W qcam support should now work (reports on how well it works are
welcome).
* Exiting xscanimage with preview window open should no longer cause
an error.
* Support for OpenStep/NeXTStep added (xscanimage and xcam require an
X server and the GTK+ libraries, though). User-level SCSI is
supported.
* SCSI support for NetBSD and FreeBSD should work now. Thanks to
NOGAYA Shigeki <nogaya@mbox.kyoto-inet.or.jp> and
Amancio Hasty <hasty@rah.star-gate.com> for relevant patches.
* New man-page sane-scsi(5) with platform-specific SCSI tips and tricks.
* SANE now builds on HP-UX (SCSI support untested) and IRIX (no SCSI
support), too.
New in 0.6:
* UMAX scanners are now supported! Kudos to Oliver Rauch
<orauch@physik.uni-osnabrueck.de> and Michael K. Johnson
<johnsonm@redhat.com>.
* scan got renamed to scanimage to avoid a nameclash with an MH program
by the same name. For consistency, xscan also got renamed to
xscanimage.
* Man-pages! There finally are at least a few man-pages. At present,
the following is covered:
saned.1 scanimage.1 xscanimage.1
sane-dll.5 sane-hp.5 sane-mustek.5 sane-net.5 sane-pint.5
sane-pnm.5 sane-qcam.5 sane-umax.5
* SANE no longer insists on using GCC. GCC works best, but other ANSI C
compilers will now also produce usable executables.
* xscanimage now supports vector options (such as gamma-tables which
are also known as intensity or tonemaps).
* The gamma-table (intensity/tone-map) handling changed in the Mustek
backend. As a result, when using scanimage it is now necessary to
specify option --custom-gamma before gamma-tables can be specified.
Also, the handling of the intensity table is now handled better in
color mode (it no longer overrides the color tables; instead
the composition of the intensity and the color channel table is
used).
* The SANE header files are now isolated in the include/sane directory
and those files get now installed as part of "make install". Thanks
to Michael K. Johnson <johnsonm@redhat.com> for this patch!
* xscanimage now displays the options' documentation strings as
tooltips (can be disabled via the "Preferences" menu).
* scanimage now supports three-pass scanning and scanning of images whose
height is not known a priori (e.g., hand-held scanners).
* The Mustek backend now supports an option to force preview scans to be
monochrome (good to save time on three-pass scanners).
* configure can now be run from any directory, as it's supposed to (makes
it easier to build SANE for multiple platforms from the same source
tree).
* xcam and xscanimage should now build on Solaris, too (thanks to
Tristan Tarrant).
* copyright info in various files have been adjusted. See LICENSE for
the general idea behind SANE licensing.
* Many, many bugfixes.
New in 0.5:
* The same xscan binary can now function as a standalone frontend or
as a gimp extension. If installed as a GIMP extension, xscan will
attach itself as Extensions->Acquire Image.
* The pnm backend now has an option to simulate a three-pass scanner.
Good for testing.
* xscan now supports previewing and (persistent) preferences.
* The build process should be much more robust now. It requires GNU make
and gcc but should be completely unproblematic otherwise. A simple
"configure" should result in a working SANE environment even on systems
where dynamic loading is unavailable. Various options are available
to tailor the SANE setup. See README for details.
* A first implementation of the HP backend now exists (for ScanJet
scanners).
* A first implementation of the net backend and saned (network daemon)
now exists. So it is now possible to scan across the network! See
backend/net.README and frontend/saned.README for details.
* xcam, a camera frontend is now included. See frontend/xcam.README for
details.
* Renamed metadl to dll.
New in 0.4:
* A first implementation of the Connectix quickcam backend now exists.
At present, only color cameras are known to work, though it shouldn't
be too hard to get the b&w versions to work as well.
* Improvements for the command-line frontend scan:
** Option settings are now applied _before_ the help info is printed.
This allows to see what the available options are with certain options
in effect.
** It can now deal with SANE_INFO_RELOAD_OPTIONS.
** It now prints the current option values in the help message (except for
vectors).
New in 0.33:
* sane_get_devices() now takes a second argument of boolean type. If it's
SANE_TRUE, then the backend must return local (non-remote) devices only.
* scan now uses the default-unit of `mm' (millimeters) again for lengths.
Using `cm' (centimeter) proved confusing since the help messages print
length values in millimeters.
* Debugging can now be controlled on a per-backend basis. The debug-level
of backend <be> is set by environment variable SANE_DEBUG_<be>. For example,
to see all debug messages of the metadl backend, set SANE_DEBUG_METADL to
a large value (say 128). The sanei.h file provides three macros
to assist in using this debug facility: DBG_DECL to declare the integer
variable that holds the debug level, DBG_INIT to initialize debugging,
and DBG to print a debug message. See backend/sanei.h and
backend/metadl.c for details and examples.
* scan now supports setting options to "auto" mode (e.g., --brightness=auto
would ask the backend to select brightness automatically if that option
supports automatic mode
* scan now allows abbreviating the values of a string-lists. Case is ignored
and the best matches is used (either longest unique match or exact match
when ignoring case)
New in 0.32:
* xscan improved much. See frontend/xscan.README and frontend/xscan.BUGS
for details.
New in 0.31:
* xscan has improved much. See frontend/xscan.CHANGES for details.
New in 0.3:
* The location of the SANE configuration files moved from /etc/saneconf
to ${prefix}/etc/sane.d. This normally expands into /usr/local/etc/sane.d.
* Real build environment. It's GNU autoconf based so all you should have
to say is:
./configure
make
make install
