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

Change:  Program name has been changed to 'xwpick'. Initial name
         conflicts 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.
