[sane-devel] xsane-0.79 released

[Oliver Rauch]

Hi.

xsane-0.79 is released.

There have been several small improvements and bug fixes.
The most important news is that a media type (especally for
negatives) can be selected. This is experimental and only
does work correct when a scanner internal gamma table is
available, for color mode there needs to be a gamma table
for each color (red, green, blue).
Take a look at the preferences menu.

It can be downloaded from:

	http://www.xsane.org



Here is the complete list of changes:

 - added test for lstat in configure/configure.in/config.h.in
 
 - when lstat is available it is used for testing netscape lock file,
   otherwise stat is used
 
 - changed order of include lines in xsane-save.c 

 - for OS/2: in xsane_back_gtk_make_path() a colon ":" is replacte by "_"
 
 - changed last argument of xsane_back_gtk_set_tooltip from char to gchar
 
 - added function xsane_widget_test_uposition(GtkWidget *gtk_window)
   that does test if gdk_window_get_deskrelative_origin or
   gdk_window_get_root_origin gives the correct positions.
   test is done with "scanning for devices" window.
 
 - in xsane.c changed #if 1 to #ifdef BUGGY_GTK_TOOLTIPS_SET_COLORS
 
 - split preview_increment_image_y in ... and preview_test_image_y,
   test is called before a byte is copied into the buffer
 
 - xsane-preview.c: preview_scan_start: preview image memory is only cleaned for
   single pass mode and 1 pass of 3 pass mode (3 pass preview does work again)
 
 - mail is sent in subprocess
 
 - added "MIME-Version: 1.0" to mail header
 
 - added mail status in mailfile, error messages while sending are stored in this file too
 
 - aclocal.m4 test for gimp: moved saving of GTK_* to beginning of routine,
   the GTK_* things should be set correct now when gimp-config is not found
 
 - xsane.h: mail is deactivated when png is not available
 
 - added preferences menu item "Medium":
   The highlight/shadow/gamma values are defined to the intensity range
   of the selected medium (e.g. agfa negative).
   If possible the analog highlight/shadow function is used,
   if not then the scanner internal digital gamma table is used
   in bot then xsane´s internal gamma correction is used.
   When the correct medium is selected it only is necessary to
   do "soft" color corrections. Because of this the 400% values
   in brightness/contrast have been reduced to 100% values now.
   This is a typically range that e.g. also is used by the gimp.
   If someone needs the larger ranges, change the following definitions
   in sane.h:
   #define XSANE_BRIGHTNESS_MIN    -100.0
   #define XSANE_BRIGHTNESS_MAX    100.0
   #define XSANE_CONTRAST_GRAY_MIN -100.0
   #define XSANE_CONTRAST_MIN      -100.0
   #define XSANE_CONTRAST_MAX      100.0
 
 - moved call xsane_update_counter_in_filename as correction for counter length from
   xsane_start_scan to xsane_scan_dialog (before open command), this way the
   counter also is correct when the file is not transformed (pnm).
 
 - corrected xsane_update_counter_in_filename: removed some pointer bugs when skipping
   exisiting filenames
 
 - added test for os2.h to configure/configure.in
 
 - added set_gimp_PLUG_IN_INFO(&PLUG_IN_INFO); for os2
 
 - removed "+0.5" in calculation of negative preview gamma table. A gamma value of 1.000 does
   not change the image data any more
 
 - effective user id is set to real user id in all subprocesses
 
 - cancel preview does now only call sane_cancel and tests for SANE_STATUS_CANCELLED while
   reading image data.   

Bye
Oliver
