       comdraw - drawtool with distributed command interpreter


       comdraw [-port n] [-import n] ['X-params'] [file]


       comdraw is a drawing editor with integrated command interpreter the user can interact with
       via stdin and stdout (or via telnet if ACE is built in).  The command syntax  is  a  semi-
       colon  separated  list  of  commands  with  arbitrary  number  of  parameters  enclosed in
       parenthesis, with support for optional parameters and keyword arguments, i.e:

              command1(arg1 arg2 arg3 :key1 val1 :key2 val2);
              command2(arg1 arg2 arg3 :key1 val1 :key2 val2)

       The literals and operators of C are all supported except for the syntax of the conditional
       operator "?:".  See the comterp documentation for more details.

       All  arguments  to  commands documented below are integers unless indicated by a suffix of
       str (which are strings embedded in quotes) or flt (which are conventional  floating  point
       numbers).  "compview" is a graphical object assigned to an interpreter variable.

       -port n, specifies the port number to accept command interpreter connections on.

       -import n, specifies the port number run  the  import  service  on.   The  import  service
       accepts connections over the net and reads drawtool format data.

       -stripped  n, brings up a comdraw without any menubar, toolbar, panner, slider, or zoomer.
       It can be controlled via stdin or telnet if built with ACE.

       -rampsize n,
        selects the rampsize used for gray-level image processing.

       -theight n, (or "-th n") selects the automatic raster tiling height.

       -twidth n, (or "-tw n") selects the automatic raster tiling width.

        enables the automatic raster tiling.

       Also see the -help message and the drawtool and idraw man pages for further options.
