*************************  snapshot-2000-12-04  *******************************

2000-12-04  Peter Kirchgessner <peter@kirchgessner.net>

        * backend/hp.c, hp-handle.c, hp.desc

	  - removed usage of gettext from lib/getopt.c
	  - removed test for libintl/gettext in configure[.in]
	  - removed intllib from frontend/Makfile.in
	* updated umax.desc

2000-12-03  Karl Heinz Kremer <khk@khk.net>

	* backend/epson.*: Version 0.1.38
	  Removed changes regarding 12/14 bit support because of SANE
	  feature freeze for 1.0.4. 
	  The following fixes are in the software compared to the version
	  prior to the feature freeze:
	  - refresh UI after a change in the scan mode setting (was not updated
	    when going from Binary to Gray or vice versa)
	  - Read values for "line distance" from the scanner instead of using
	    hardcoded values. This makes sure the backend always uses the correct
	    values regardless of firmware version.
	  - Fixed an "off-by-one" error in the color reordering routine that 
	    caused weird artifacts in some instances.

2000-12-03  Karl Heinz Kremer <khk@khk.net>

	* backend/epson.c: Fixed off-by-one in color reordering

2000-12-02  Karl Heinz Kremer <khk@khk.net>

	* backend/epson.*: Read information about optical resolution 
	  and line distance from scanner instead of hardcoded values.
          Add support for color depth > 8 bits per channel. 
	  (can use 12, 14 and 16 bits per channel)
	  EPSON backend is now version 0.36 

2000-11-30  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* changed backend/Makefile.in:
	  wrong old installation of libsane.la
	  $(INSTALL_PROGRAM) libsane.la $(libdir)/libsane.la
	  to this:
	  $(LIBTOOL) $(MINST) $(INSTALL_PROGRAM) libsane.la $(libdir)/libsane.la

2000-11-30  Henning Meier-Geinitz <hmg@gmx.de>

	* README.irix: Removed. Problem with libjpeg is solved.

	  entry about net backend segfaulting if using net:localhost. Removed
	  artec O_SYNC problem. Removed Irix jpeg problem. Removed PTAL 
	  addition.
	* doc/saned.man: Added paragraph about xinetd (from Matt Mozur 
	  <matt.mozur@sourwood.net>). Removed links to backends, added
	  sane-"backendname" instead.
	* doc/sane-net.man: Added comment about segfaults if scanning
	  on localhost.

2000-11-30  Chris Pinkham <cpinkham@infi.net>

	* artec.c: removed O_SYNC for posix compatibility, converted variable
	  to unsigned char to get rid of overflow error.  Changed version
	  to 0.5.15.

2000-11-30  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* changed sane-config.in again:
	  sane-config --libs has to print all libs
	  that the sane libs depend on.
	  This is not needed for shared libs and that
	  was the reason why I removed all libs but "-lsane".
	  But when linking against static sane libs we need
	  to know about all necessary libs.

*************************  snapshot-2000-11-28  *******************************

2000-11-28  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* added SANE_CHECK_JPEG to aclocal.m4 and configure.in

	  1.0-100. Added option fast-preview that tries to use the fastest
	  mode available for preview. This is supported for the 3-pass
	  scanners (was option "preview in gray") and some of the
	  ScanExpress scanners (6000 SP, 12000 SP Plus). Use #include 
	  "../include/sane/...". Put option force-wait into mustek.conf
	  (disabled). Removed block mode for Paragon 6000 SP and 8000 SP. 
	  Code cleanup. More debug output. Details in backend/mustek.CHANGES.
	* doc/.cvsignore: Added sane-as6e.5 and sane-nec.5.

2000-11-24  Henning Meier-Geinitz <hmg@gmx.de>

	* AUTHORS: Removed authors of xscanimage and xcam (now in 
	  sane-frontends).
	* README.unixware2, README.unixware7: X-frontends are no longer
	  included. Removed comments and sourcecode of "rev" (not supported/used
	  in backends/Makefile anymore).
	* sane.lsm: X-frontends are no longer included. Used blanks instead of
	  tabs.
	* doc/scanimage.man: Removed links to backends, added generic link
	  instead.
	* doc/.cvsignore frontend/.cvsignore: X-frontends are no longer included.

2000-11-24  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* changed configure.in, configure frontend/Makefile.in
	  and backend/Makfile.in:
	  The shared libraries required by the backends are linked to
	  the backends (they have been linked to the frontends before).
	  Only libintl is linked to the frontend.
	* changed tool/sane-config.in, sane-config --libs => "-lsane",
	  all other libraries are linked to the backend libs now

2000-11-24  Jochen Eisinger <jochen.eisinger@gmx.net>

	* doc/scanimage.man doc/saned.man: updated description of password
	  file
	* sanei/sanei_auth.c frontend/saned.c frontend/scanimage.c: replaced

	  resource before calling the auth_callback function

2000-11-23  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* removed doc/xcam.man, doc/xscanimage.man and
	  updated doc/Makefile.in
	* changed configure.in and frontend/Makefile.in,
	  "-lintl" is not added to @LIBS@ any more, @INTLLIBS@
	  is defined instead now, this is necessary because "-lintl"
	  has to be added to the frontends and not to a backend and
	  sane-config --libs must not list it.
	* Added "Introduction" to README that tells about
	  the new X-frontend package
	* removed gimp and gtk parts from include/sane/config.h.in
	* removed gtk test from aclocal.m4

	  warnings. 
	
2000-11-23  Karl Heinz Kremer <khk@khk.net>

	* backend/epson.c:  Display "Set Focus" control only for scanners that
	  can actually handle the command.

2000-11-22  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* changed configure and configure.in, removed test for sting.h/strings.h
	  this is not needed because we use strchr instead (always in string.h)
	  of index (sometimes in string.h, sometimes in strings.h)

	* changed ltconfig for aix4*, repleace -o $objdir/$soname by -o $lib,
	  the shared libraries are handled correct now

2000-10-15  Jochen Eisinger <jochen.eisinger@gmx.net>

	* include/sane/sanei_debug.h: sanei_debug_init was only declared
	  if VARARG macros are supported. Fixed this.

2000-10-08  Jochen Eisinger <jochen.eisinger@gmx.net>

	* sanei/sanei_pa4s2.c: fixed all but one compiler warning

2000-10-03  Henning Meier-Geinitz <hmg@gmx.de>

 	  find non-SCSI scanners.
	* doc/scanimage.man: Add examples for SANE device names.
	* frontend/scanimage.c: Output message when no devices are found.
	  Add example for devicename to --help message. Print warning
	  when a Unix devicename is used instead of a SANE device. Removed
	  compiler warning.
	* TODO: Removed entries about the fgets and include issues in
 	  umax. Removed entries about scanimage device name
 	  documentation. Added a point about xscanimage problems with the
 	  new GIMP API.
	* backend/mustek.* doc/sane-mustek.man: Update to Mustek backend
 	  1.0-98. Fixed segmentation fault in sane_init. Enabled double
 	  buffering. Clear inquiry buffer before using. Paragon 1200 SP now
 	  uses LD_BLOCK color correction. Removed LD MFS (wasn't used
 	  anymore). Fix sane_cancel for Paragon series II scanners. Fix
 	  halftone and grain for Paragon series II scanners. Backtracking is
 	  used automaticly by all scanners now. Some safety checks, code
 	  cleanup and more debug output. Details are in 
	  backend/mustek.CHANGES.

2000-10-02  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

	* Updated umax backend to sane-umax-1.0.3-build-24
          take a look at backend/umax.CHANGES for details

2000-10-02  Oliver Rauch <Oliver.Rauch@Wolfsburg.DE>

        * sanei/sanei_constrain_value.c:
          if checked option is a range and the value is out of
	  range the value is now corrected to the minimum or maximum
	  allowed value and SANE_INFO_INEXACT is set.
	  The old version returned with an error. This caused problems
	  when the value was a little bit out of range because of rounding
          errors.

2000-09-30  Henning Meier-Geinitz <hmg@gmx.de>

	* backend/pnm.c: Fixed three segfaults due to buffer overruns:

 	  warnings. Added DBG lines for every SANE API call.
	* TODO: Added entries about the backend:devicename issue. Add a
	  comment about fronends not to crash when length is -1. Added entry
 	  about sane-pie. Added point about fronends not checking if too 
	  much data is delivered with sane_read.
	* PROJECTS: Added entry about sane-pie.

2000-09-24  Henning Meier-Geinitz <hmg@gmx.de>

	* backend/mustek.*: Update to Mustek backend 1.0-97. This is a

  	  Added support for Paragon 1200 SP Pro and ScanExpress A3 SP.
  	  Removed detection of " C04" and " C12" (don't seem to exist).
  	  Changed SCSI request scheme. Sane_read can read more than 4096
 	  bytes from pipe. Minimum dpi is 30 now. Fixed LD correction for
 	  Paragon 1200SP 1.06 and 1.11.  Read SCSI buffer into big block and
 	  do LD after that for Paragon one-pass scanners. New option
 	  "blocksize" in mustek.conf. Better detection of the scanner type
 	  (three-pass, Paragon I, ...). Fixed possible segmentation faults
 	  in Paragon 600 II N LD code, scsi_sense_wait_ready and
 	  sense_handler. Decreased maximum scan size of Paragon 800 II
 	  SP. For three-pass scanners: fixed stop_scan and speed code, scan
 	  area is in pixels now, added RGB brightness and contrast, use
 	  +-100% for brightness and contrast. Return SANE_STATUS_CANCELLED
 	  when scan was cancelled. Option "force backtracking" is enabled by
 	  default, "scan speed" is set to "fastest". Added option
 	  "force-warn" for mustek.conf.  Rewrote halftone mode. Better error
 	  handling and more debug output.
	* TODO: Clarified point about image data polarity. Moved point about
	  xscanimage not updating the progress bar for 3pass scanners to
	  frontend section. Removed umax entry in "frontends". Removed entry
	  about alpha channel (was added to LEVEL2 file).
	* LEVEL2: Add point about image data polarity.
	* frontend/scanimage.c: Removed some warnings.

        * README: Removed comment about xscanimage error message. Added
          comment about find-scanner (may find scanners not supported by
          SANE).
	* tools/README: Added comment about find-scanner and some lines
 	  about sane-desc.el and sane-config.
	* tools/find-scanner.c: Added comment about scanners not supported
 	  by SANE. Removed some warnings.

2000-09-17  Petter Reinholdtsen <pere@td.org.uit.no>

	* config.guess config.sub : Upgraded to latest version from
	<URL:ftp://ftp.gnu.org/pub/gnu/config/>.

          David Paschal (paschal@rcsis.com)
            Added support for flatbed HP OfficeJets.
          fix problem with cancel preview
          fix timing problem between killing child and writing to pipe
          change fprintf(stderr,...) to DBG
          change include <sane..> to "sane.." in hp.h
          change handling of options that have global effects.
            i.e. if option scanmode is received (has global effect),
            all options that "may change" are send to the scanner again.
            This fixes a problem that --resolution specified infront of
            --mode on command line of scanimage was ignored.
            NOTE: This change does not allow to specify --depth 12 infront of
            --mode color, because --depth is only enabled with --mode color.
          add depth greater 8 bits for mode grayscale
          add option for 8 bit output but 10/12 bit scanning

2000-08-24 Gerhard Jaeger <g.jaeger@earthling.net>

	* backend/dc25.c: Apply patch by Peter Fales.

1999-04-11  David Mosberger-Tang  <David.Mosberger@acm.org>

	* include/sane/config.h.in: Declare return type of strdup(),
	strndup(), and strsep() if these functions are not part of the
	standard libc.  This breaks the GNU convention of not declaring
	standard C library functions but is required in these cases
	because the functions return pointers.  On a 64 bit platform, bad
	code is generated if a function is (implicitly) declared to return
	an "int" and then returns a pointer.  To minimize the risk of
	compile errors due to conflicting prototypes, we don't specify a
	prototype though (just the return type).

	* backend/dll.conf: Comment out dc25 and dc210 backends as those
	are VERY slow to initialize when no camera is attached.

	* backend/epson.desc: Add Epson GT-7000.

1999-04-06  David Mosberger-Tang  <David.Mosberger@acm.org>

	(patch by Mikko Tyo"la"ja"rvi <mikko@securitydynamics.com>).

	* backend/snapscan.c (start_reader): Don't redirect scanner file
	descriptor to fd 0 (needlessly breaks FreeBSD and other platforms
	that don't use real file descriptors for the scanner.

	* backend/microtek2.c: Apply Bernd's patch to fix "green-ness"
	bug.

	* backend/umax.BUGS: Applied Oliver's latest patch.

  	Earlier, substrings would also match.

	* backend/snapscan.c (sane_snapscan_*): Changed API entries from

	* backend/snapscan.c (add_device init_options inquiry
 	sane_snapscan_get_parameters sane_snapscan_start
 	sane_snapscan_set_io_mode sane_snapscan_read) backend/snapscan.h
 	backend/snapscan.desc: Rewrote scanner detection code to loop over
 	array of supported SCSI names.  Added AGFA SnapScan 1236s support.
  	It seems to be compatible with SnapScan 600.
	Make sure to not add the same device more then once to the device
 	list.  Bugfix in sane_snapscan_read() triggered on EOF.

1999-04-04  David Mosberger-Tang  <David.Mosberger@acm.org>
	* PROBLEMS: Note that /proc/sys/kernel/sg-big-buff is available
	since Linux kernel v2.2.

	someone wants to fix that code, the previous (unreliable) version
	of the PNM backend is in backend/pnm.c-bad.

	* doc/sane.tex (subsection{Resolution Option}: Remove section
	4.5.5---it was a duplicate of section 4.5.2 (Scan Resolution
	Option)!

	* backend/microtek2.c (chunky_proc_data): Merge in latest changes

	* backend/microtek2.h: Ditto.

	* backend/st400.desc: New file.

	* backend/epson.c (sane_open): Check for NULL or empty
	dummy_dev.sane.name to avoid segfaults.  (Suggested by Yuri
	Dario).

	* sanei/sanei_scsi.c [USE = LINUX_INTERFACE]: Make "cdb" last
	member in "struct req" and change size of "data" to 1 byte to
	allow dynamic sizing of data buffer based on the value of
	sanei_scsi_max_request_size.
	(sanei_scsi_req_enter): Calculate size of request based on
	sanei_scsi_max_request_size.  A similar patch was proposed
	by Petter Reinholdtsen.

	now.  Embarassing, but fortunately only the snapscan backend seems
	affected by this change.

	* backend/dll.c (load): Use SANE_CURRENT_MAJOR, not V_MAJOR (the

	"inline" if necessary.

	* backend/dc210.c (init_dc210): To send break, use tcsendbreak()
	if available or TCSBKRP or TCKSBRK ioctl() if available or fall
	back to doing nothing if none of these are supported.  This may
	cause the backend to work incorrectly on platforms that do not
	support one of the above methods for sending a break, but at least
	it will compile that way.

1998-12-12  David Mosberger-Tang  <David.Mosberger@acm.org>

	* backend/hp.desc: Updated with Peter's latest version.

1998-11-30  David Mosberger-Tang  <David.Mosberger@acm.org>

	* backend/snapscan.c (sane_snapscan_start): Use INT_MAX instead
	of non-portable MAXINT.
	Don't include Linux-specific <values.h>.

1998-11-22  David Mosberger-Tang  <David.Mosberger@acm.org>

	* backend/ricoh.h (_4btol): Replace "__inline" by "inline".

	* backend/abaton.c (sane_control_option): Assign word values to

	significant.

	* configure.in
	(lib/Makefile.in,lib/strcasecmp.c,frontend/saned.c): Use

	defined (by Peter Kirchgessner).

	* frontend/Makefile.in (INCLUDES): Mention @GTK_CFLAGS@ as part of

	is guaranteed to contain CPP include directives only.  (Reported
	by Kevin Dalley <kevind@rahul.net>.)

Fri Mar 28 21:33:36 1997  Gordon Matzigkeit  <gord@gnu.ai.mit.edu>

	* configure.in: Make the QuickCam device conditional on whether or
 	not the ioperm function exists.

	* sanei/sanei_scsi.c: created a stubbed version of sanei_scsi_cmd.

	* README: Add pointer to frontend & backend specific README files.

	* backend/net.c (connect_dev): Ensure dev->ctl gets closed and

	ignore old GTK versions against which we can't build.

	* (config.sub): Replace with version that comes with
 	autoconf-2.12.  The version that came with libtool-0.9
	doesn't like i686-unknown-linux.

	this function.

	* frontend/gtkglue.c (unit_string): New function.
	(panel_build): Append unit_string () to option's title if
	the unit is not SANE_UNIT_NONE.  Use "title" instead of opt->title

	(max - min + eps) where eps is 1 for integer coordinates and
 	SANE_UNFIX(1) for fixed-point coordinates.
	(display_partial_image): Support different scaling in x/y
 	direction.  In the case where surface_unit == SANE_UNIT_PIXEL,
 	compute xscale/yscale based on the ratio between the _expected_
 	width/height and the actual width/height.  If they're not equal,
 	the backend must be doing some scaling (e.g., transfer-scale in
 	the qcam backend).

	* frontend/xscan.c (init): Disable gtk_rc_parse () calls for now
	since gtk styles seem to be a bit buggy right now.

 	default-button---it's too easy to cancel by mistake otherwise.

	* frontend/sane-style.rc: New file.

	* frontend/xscan.c (init): New function.  Parse gtk_rc_parse ()
	on /usr/local/share/sane-style.rc and ~/.sane/sane-style.rc if

 	until GTK+ has been fixed.
	(idle_handler): New function: rebuild dialog if dialog->rebuild is
 	set.

 	tells me GTK is not designed to have a widget rebuilt while a
 	submenu is active.
	(gsg_refresh_dialog): Ditto.

Thu Mar 27 14:54:23 1997  Gordon Matzigkeit  <gord@gnu.ai.mit.edu>

 	is on (instead of pixel unit).
	(mode_select): Set bit 3 in mode byte only if
 	MUSTEK_FLAG_USE_EIGHTS is off.
	(encode_resolution): Don't do funky encoding for 3-pass scanners
 	in 10% resolution mode.  It seems the docs are wrong and the
 	actual scanners require a much simpler setup.
