Xwpick 2.20 (Rev: 20/09/94)
===========================

Change:  The <SPACE> bar interaction has been removed from the default
         behaviour of the program; now if you want to have a pause
         after the window (or rectangular area) has been selected you
         should use a '-pause' option.

Added Feature: '-pause' waits click of the <SPACE> bar; this option
               gives to the user a possibility to change the selected
               image just before outputing to a file;

Added Feature: '-format' allows to choose the output format without
               regards to the extention in the file name; when '-format' 
               is in the parameter list and the output file name is
               omitted, the output is directed to stdout, thus it's now
               possibile to use xwpick in different bindings, e.g.

               xwpick -format ps -window root | lpr

Enhancement:   In previous versions although the program asked to press
               the <SPACE> bar to start the grabbing process, it responded
               on pressing of any key. Now the trigger key is restricted
               exactly to the <SPACE> bar. This allows to display popup
               menus which appear on the screen only when pressing the
               Control-Key (or some other keys) together with the mouse
               button, e.g. the VT options popup menu of xterm.

Xwpick 2.10 (Rev: 15/08/94)
===========================

Change:  Program name has been changed to 'xwpick' to avoid a
         conflict with 'xpick' by Gerry Tomlinson, which is
         "...an X11 Athena Widget implementation of pick, from
         "The Unix Programming Environment" by Kernighan and Pike..."

Bug Fix: Sometimes 'xpick' produced wrong PostScript files for large
         windows with a lot of space of the same color. The reason:
         ClearCode in LZW encoding always was output as a 12 bits code.  

Change:        Option '-' has been changed to '-local'.

Added Feature: '-window id' selects window by id number.

Added Feature: '-gray' tranfers image to gray scale. It can be used
               to optimize output on level 1 PostScript printers. On
               level 2 PostScript printers practically there is no
               difference in rendering time between color and gray scale
               images. 

Added Feature: '-reverse' tranfers image to reverse colors. It can be used
               to save toner on gray scale printers in case when the image
               has a lot of dark space. 

Added Feature: On VAX/Alpha OpenVMS it is allowed to use VMS style of
               parameter input, e.g. xwpick/gray/window=0x8400 pict.gif
               (see vms_parser(...) routine in xwpick.c).

Added Feature: Help file for VMS.

Enhancement:   During output to PostScript on gray scale (or B&W) stations 
               it is automatically generated gray scale PS file
               ('image' operator is used instead of 'colorimage').   

Enhancement:   Additional check for existence of 'setcolorspace' operator
               is used to recognize on what kind (level 1 or 2) of PostScript
               printer the file is being output. Only in case when both 
               'filter' and 'setcolorspace' operators are known the level 2
               LZW/ASCII85 filtes will be invoked, otherwise inline
               decompression code is executed.
