NAME


comdraw - drawtool with distributed command interpreter

SYNOPSIS


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

DESCRIPTION


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.

OPTIONS


-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.
