 - setup of faxoptions: normal, fine and postscript option is saved now


xsane-0.27 -> 0.28:
-------------------

 - added option negative into enhancement and changed create_gamma
   draw_histogram and auto_enhancement to work with it!

 - increased contrast range from -100..+100 to -100..+200
   and brightness range from -100..+100 to -200..+200
   because the old values were not sufficent for scanning negatives

 - added support for resolution of type CONSTRAINT_WORD_LIST 
 - xsane-mode (scan, copy, fax) can be selected as command line option (-s, -c, -f) now
 - most texts that are defined in xsane are defined in xsane-text now


xsane-0.29 -> 0.30:
-------------------

 - removed bug in xsane_set_resolution, now highest resolution can be set if
   resolution is a list!
 - added RGBI support - must be activated in xsane.h (SUPPORT_RGBI)
 - added options rgb default and negative to preferences
 - enhancement values are saved with device settings now
 - The filename can be specified now for the file in which the device settings are saved
   or from which they are loaded.
   - changed extension from ".rc" to ".drc" (device rc)
   - added header "XSANE_DEVICE_RC" to identify it as device-rc-file
 - added calculation for color components to auto enhancement
 - pipette functions: middle mouse button defines shadow/gray/highlight
   for color components, left mouse button only defines gray values!
 - auto enhancement values are set to standard values in
   xsane_calculate_histogram if no values could be calculated
 - histogram is cleared when sensitivity is set to false
 - improved calculation of auto enhancement values
 - increased contrast range from -100..+200 to -100..+300 (gray) and
   -300..+300 (color) and brightness range from -200..+200 to -300..+300


xsane-0.30 -> 0.31:
-------------------

 - changed filename character transformation: erase " ", "_" -> "__", "/" -> "_"
 - device settings standard file name is vendor:model
   so it does not matter any more if the sg-device name has changed
 - the xsane main window can be a fixed or a scrolled, resizable window now.
   selection is done with setup/display/"main window fixed",
   the main window mode can be overwritten by specifying a command
   line option:
   -R or --Resizeable activates the resizeable, scrolled window,
   -F or --Fixed activates the fixed (non resizable) window (default)
 - histogram is cleared when info dialog or about dialog is opened
 - changed version option from -V to -v
 - added support for Automatic Document Feeder (scan until error)
   this is experimentary because in the SANE-standard there is
   no way defined how a frontend can identify an ADF.
   The backend has to load the next document automatically!
 - in xsane_enhancement_update replaced gtk_signal_emit_by_name
   by gtk_signal_emit
 - moved more texts to xsane-text.h
 - changed all RGBI -> RGBA because the 4th channel is ALPHA
   I think that SANE_FRAME_RGBA will be added to the sane standard
 - gtk+-1.2.0 is minimum requirement: removed tests for
   gtk_tooltips_set_tips, gtk_scrolled_window_add_with_viewport
   and gtk_events_pending that were needed for gtk+-1.0.x
 - added option "--device-settings file" to define default
   filename for device-settings
 - corrected "legal" size in preview
 - added device_text to info and preview window title
 - moved color definition to xsane_creat_histogram_dialog
 - pixmap colors depend on histogram_dialog now because
   the histogram dialog is the first dialog that exists
 - renamed all gtk functions like defined in gtkcompat.h
   (gtk+-1.0.x -> gtk+-1.2.x)
 - removed bug in device selection, device can be selected
   now with keyboard
 - xsane info window prints gamma depth "none" in 1 bit modes


xsane-0.31 -> 0.32:
-------------------

 - added option --no-mode-selection/-s to disable menu for
   xsane mode selection
 - prepared text outputs (in xsane-text.h) for NLS/gettext support
 - multiple \n in scanf while reading saved preview image removed
 - added AM_PROG_CC_STDC to configure.in for HP/UX
 - added a break statement after each default in switch block
 - changed test for multiple image scan, when sane_read returned with
   SANE_STATUS_GOOD when the image is finished we start a new scan,
   SANE_STATUS_EOF is expected when scanning should be stopped.
   This way the Automatic Document Feeder is supported a way
   like planned in the sane standard, the backend says
   if the frontend shall call sane_start repeatadly.


xsane-0.32 -> 0.33:
-------------------

 - removed change about SANE_STATUS_GOOD in multiple image mode.
   Adf mode is detected by scanmode again. This would be better
   selected by a mulit_image bit in the preferences block.
 - added common rotuine xsane_set_sensitivity to xsane-front-gtk.c
 - renamed xsane_test_adf to xsane_test_multi_scan


xsane-0.33 -> 0.34:
-------------------

 - the preview selection is based on device coordinates instead of
   preview window coordinates now
 - added preview buttons and preview viewport to xsane_set_sensitivity
 - info and about dialog use xsane_set_sensitivity now
 - dummy_filename is created and opened for writing AFTER sane_start is called.
 - sane_start() == NO_DOCS is not handled as error any more
 - xsane_scan_done -> sane_cancel is called now if an error occurs
 - if an error occurs while scanning the created file is removed
 - xsane windows/buttons get inactive while setup dialog is open
 - xsane_scan_done -> sane_cancel is called when main window is closed
   (while scanning)
 - if there are no standard device settings at program startup, xsane
   take the backend predefined resolution (before this was set to 100)
 - if no scanarea options are given, the preview works with
   [0,INF] instead of [-INF,INF] now
 - transformed all gif files in directory doc to jpeg format because of
   all the trouble about the gif licence.  Will never use gif again!


xsane-0.34 -> 0.35:
-------------------

 - corrected doc/Makefile.in for change gif->jpg
 - added tiff compression type selection for multi bit and one bit images to
   setup:
   none, CCITT 1D Huffman compression, CCITT Group 3 Fax compression,
   CCITT Group 4 Fax compression, Lempel-Ziv & Welch, JPEG DCT compression,
   pack bits
 - implemented real single-bit format for tiff
 - setup/jpeg quality selection is enabled if jpeglib or libtiff is available
 - added gimp_image_set_resolution(...) to gimp saving routine
 - added test for libgimp/gimpfeatures.h to configure.in and config.h.in
 - disabled sensetivity while filename browse window is open
 - added handling if fileselection window was closed
 - moved filename "Browse" button from the right to to the left with disk-image inside
 - (added image filetype menu to the image filename line - not ready)
 - replaced button-texts negative, rgb default, auto, default, store and
   restore by icons


xsane-0.35 -> 0.36:
-------------------

 - moved xsane_generate_dummy_filename in xsane-scan.c out of a
   #ifdef HAVE_LIBGIMP_H block
 - changed some icons
 - added #ifdef HAVE_LIBTIFF around TIFF-relevant definitions in
   xsane_setup_dialog in xsane-setup.c
 - included NLS/gettext version 0.10.35
 - texts that are created by xsane can be converted to other languages
   now - texts created by the backend can not be translated yet!
 - added gettext relevant routines to aclocal.m4 and correct some bugs
 - added french translation - thanks to Vincent Renardias <vincent@ldsol.com>
 - added german translation table
 - translation files "*.po" are created by "*.po.in" with help of the
   preprocessor of gcc, all texts are #defined in frontend/xsane-text.h


xsane-0.36 -> 0.37:
-------------------

 - added some texts to xsane-text.h and newlanguage.po.in[.in],
   created file add-0.37.po.in where the new entries are listed
 - moved generation of xsane.backend (backendname like umax)
   from xsane_help_build_menu to xsane_device_dialog, needed for
   translation of backend options
 - added translation for backend options:
   Backend translation is done with translation table sane-BACKENDNAME.mo 
 - removed bug in preview_update_selection()
   (forgotten p->selection.active = TRUE)
   The selection box is updated correct now
 - removed bug in aclocal.m4: not fount "-lintl" when gettext is in glibc


xsane-0.37 -> 0.38:
-------------------

 - changed STANDALONE -> XSANE_STANDALONE and
   GIMP_EXTENSION ->  XSANE_GIMP_EXTENSION because GIMP_EXTENSION
   now (gimp-1.1.10) is used in the Gimp
 - changed brightness and contrast range maximum form 300 to 400 %
 - moved gimp installation texts to xsane-text.h
   added entries to po/newlamguage*
 - xsane -g now does not print anything and does not abort if gimp
   support is compiled in
 - changed lib/Makefile.in and sanei/Makefile in, make install should
   work without a previous make now
 - xsane gimp-plugin is selected via file/acquire now when
   gimp-version >= 1.1.9
 - . removed ../intl/libintl.a form frontend/Makefile.in and
   . added CATOBJEXT=UNKNOWN and XGETTEXT=":" in if "gettext is in libc"
     to aclocal.m4
   hope this solves problems with missing "-lintl" now on all systems
 - moved "show xxx" menu items form menu "Preferences" to menu "View"
 - added continuous update to histogram sliders and preview selection
 - added preferences menu item "Update policy"
 - now options are only changable if SANE_CAP_SOFT_SELECT is set
 - added test for bitdepth in xsane_scan_dialog for GIMP mode,
   error message pops up when unsupported bit depths are selected
 - moved case XSANE_PNM16 out of a #ifdef HAVE_LIBPNG block
 - position of all windows and size of main window and preview window
   is save in device settings, setting preview window geometry
   does not work because window does not exist at relevant times.


xsane-0.38 -> 0.39:
-------------------

 - bounded contrast to >=-100.0
 - Added test if GIMP_CHECK_VERSION is defined


xsane-0.39 -> 0.40:
-------------------

 - device name is saved in drc file now
 - xsane version is saved in drc file now
 - warning is printed if device rc file was not created for active device
 - removed member device from struct preferences - was never used
 - changed frontend/Makefile.in (XSCAN->BINPROGS)
 - changed configure.in:
   - changed order of some checks
   - added status messages at the end
   - added "--enable-intl-patch" which adds -lintl to check for libsane
   - added "--disable-gimp"
   - added "--disable-jpeg"
   - added "--disable-tiff"
   - added "--disable-png"
 - moved xsane_generate_dummy_filename and fopen() into if XSANE_STANDALONE block,
   there is no empty file created in gimp mode any more.


xsane-0.40 -> 0.41:
-------------------

 - renamed xsane-incons.h -> xsane-icons.c and xsane-icons-def.h -> xsane-icons.h
 - moved all includes that are needed by most xsane sources to xsane.h
   problem with missing stdio.h is solved that way
 - changed configure script:
   - check for sane is moved to the end because of missing libintl,
   - check for png is done with x_includes and x_libraries,
     and libpng is added to lib after all checks are done


xsane-0.41 -> 0.42:
-------------------

 - changed configure.in, error message about missing sane is also printed if sane.h
   is not found.
 - changed info row (size box, start button): the start button is made smaller when
   the info box needs more place
 - changed calculateion of size in info row from unisgned long to float
   because unsigned long / 10 were to small to fit A4 with 1200x1200 dpi
 - changed png part of configure, HAVE_LIBPNG is now defined again
 - corrected png lineart saving


xsane-0.42 -> 0.43:
-------------------

 - disabled LZW-compression for TIFF.
   Unisys holds a patent for LZW compression. I am not sure
   about the licence status of LZW and TIFF. GIF is not supported
   because of the licence problem. LZW for TIFF is disabled now.
 - removed all LZW entries in sourcecode and translation tables


xsane-0.43 -> 0.44:
-------------------

 - renamed NOTEBOOK_PRINTER_OPTIONS to NOTEBOOK_COPY_OPTIONS
 - added sane-problems-doc.html to the help menu
 - added functions around "by ext" menu
 - all functions in xsane-back-gtk.c are named with xsane_back_gtk_* now


xsane-0.44 -> 0.45:
-------------------

 - added *s = 0; in sanei_codec_ascii.c when reading a string that
   does not start with '"'

 - added test "if (!w.status)" when reading a string in sanei_load_values.c
   the missing test caused a segfault when a string was expected but
   the line did not start with '"'

 - merged together all needed sanei_* routines in xsane-rc-io.c
   and renamed all sanei_* to xsane_rc_io_*, removed subdir sanei
   and changed xsane.c and xsane-preferences.c to use xsane-rc-io.[ch]
   and reprogrammed some things.

 - renamed all xsane_pref_device_* to xsane_device_preferences_*
   and moved them to xsane-device-preferences.c

 - renamed sanei_w_[load|save]_values to xsane_device_preferencs_[load|save]_values
   and moved them to xsane-device-preferences.c


xsane-0.45 -> 0.46:
-------------------

 - changed xsane_rc_io_w_space: returns ENODATA instead of EINVAL at EOF

 - added xsane_rc_io_w_skip_newline

 - changed xsane_device_preferences_load_values:
   - begin at start of file is only inciated if w.status == ENODATA 
   - if w.status is an other error, the line is skipped

 - moved and renamed w_string, w_int, w_double from xsane-preferences.c
   to xsane_rc_pref_* in xsane-rc-io.c

 - repleaced fprintf/fscanf for reading xsane device preferences by
   xsane_rc_io_w_* routines
   This way the floating point values (xsane- gamma, brightness and contrast)
   are saved different and the *.drc-files are incompatible in that point.

 - added test for lineart mode (depth == 1) in xsane_enhancement_update
   solves segmentation fault problem when device settings with lineart enabled
   are loaded
 

xsane-0.46 -> 0.47:
-------------------

 - if helpfile viewer is netscape-remote and netscape is not running
   it is started

 - replaced ENODATA (used for EOF detection in xsane-rc-io and
   xsane-device-preferences) by XSANE_EOF (=-1)
   (ENODATA is not defined on all systems)

 - If faxproject does not exist, project data entries are made insensitive
   and buttons "send project" and "delete project" are replaced by "create project"

 - Added missing "&" in xsane_device_preferences_save_values:
   xsane_rc_io_w_array(w, &len, (void **) &word_array, (WireCodecFunc) xsane_rc_io_w_word, sizeof(SANE_Word));
   that cause segmentation fault when writing bool, int or fixpoint arrays.
 

xsane-0.47 -> 0.48:
-------------------

 - "START" button is made insensitive in fax mode if project does not exist.

 - Preview window is created at the same time as the main dialog and it is destroyed
   at program end. Disabling "show preview" hides the preview window. This way the preview
   window placement does work correct.

 - set default values in xsane_device_preferences_load_file(char *filename)
   before reading the saved values, show_preview default = true

 - Mouse pointers display relevant mode icons in preview window now.

 - In copy mode the maximum selectable size that fits to the selected printer is drawn
   by a rect now. Selection is limited to the printer size.

 - if no local xsane.rc, xsane-style.rc or DEVICE.drc file exists it is loaded from SANE_DATA_DIR/xsane

 - all xsane rc files are placed in a subdirectory xsane now (~/.sane/xsane, SANE_DATA/DIR/xsane)

 - temporary files (previews, conversions) are saved in /tmp (defined in SANE_PATH_TMP in xsane.h) now

 - added window decoration icon (top left) to each xsane window (does work with kwm, does not work with fvwm2)

 - added warning icon and error icon

 - removed xsane_files_exit_callback, now xsane_scan_win_delete is used for all exit program calls

 - conversion-* and preview-* files are created with permission "-rw-------",
   images- and project-files are created with "preferences.image_umask"
   xsane.rc and *.drc are created with XSANE_DEFAULT_UMASK defined in xsane.h

 - added file permission selection in preferences/saving options for image file and for directory (faxproject)

 - disabled fileoptions (mkdir, rm, mv) in loading/saving preferences


xsane-0.48 -> 0.49:
-------------------

 - added support for different x/y resolutions and zoom factors,
   the y-resolution slider is added to the xsane main dialog now

 - in gimp mode x- and y-resolution infos are set correct now

 - added resolution and zoom icons for x- and y-dimension

 - added fax_width and fax_height to preferences

 - added paper size frame in fax mode preview

 - added czech translation - thanks to by Stanislav Brabec <utx@k332.feld.cvut.cz>

 - changed gimp_install_procedure(...): "RGB, GRAY" -> 0

 - changed printer geometry setup from 1/72 ich to mm

 - added setup entries for fax- width, height, left_offset and bottom_offset

 - corrected terminating \0 of strings in sane_choose_device

 - when button "Negative" is pressed the white/gray/black points
   are also inverted
