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.
-tile,
enables the automatic raster tiling.
Also see the -help message and the drawtool and idraw man pages for further options.
