The following classes provide an interface to DEC's Easy Draw application.
Easy Draw is an application written in scheme which alows easy drawing on the
X 11 Window system. The CNCL simulation programs communicate via UNIX
pipes with Easy Draw.
These classes use Xcolors and Xfonts. A list of the colors you can
find at /usr/global/lib/X11
in the file rgb.txt, for a list of
fonts use the command xlsfonts
. Only the color 'clear' is added
to allow transparent objects in the drawing.
Additionally to the colors some stipple patterns are defined at
EZD. They are called s0, s1, ... , s16, where the number is
representing the amount of drawn pixels (in the defined color) in a
square of 4-by-4. However, this option is ignored when postscript files
are written.
You can find additional information about ezd at the man pages.
