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. DRAWING COMMANDS

xylist=center(compview :xy :yx :x :y :scrn) -- center of compview (dflt :xy) rectlist=mbr(compview :lbrt :lrbt :scrn) -- minimum bounding rectangle of compview (dflt :lbrt) ptlist=points(compview) -- return point list from compview graphic GRAPHIC STATE COMMANDS
font(fontnum) -- set current font from menu brush(brushnum) -- set current brush from menu pattern(patternnum) -- set current pattern from menu colors(fgcolornum bgcolornum) -- set current colors from menu colorsrgb(fgcolornum bgcolornum) -- set current colors by RGB name. The colorname format is "#RGB" for 4 bits, "#RRGGBB" for 8 bits, #RRRGGGBBB for 12 bits, #RRRRGGGGBBBB for 16 bits nfonts() -- return size of font menu nbrushes() -- return size of brush menu npatterns() -- return size of pattern menu ncolors() -- return size of color menus DIRECT MANIPULATION COMMANDS

/UNGROUP COMMANDS newgroup=growgroup(groupview compview) -- add graphic to existing group graphic newgroup=trimgroup(groupview compview) -- remove graphic from existing group graphic COMPONENT AND ATTRIBUTE COMMANDS
compview=setattr(compview [:keyword value [:keyword value [...]]]) -- set attributes of a graphic component attrlist(compview) -- return attribute list of component compview=frame([index]) -- return composite component for a frame, defaults to current val=at(list|attrlist|compview n :set val :ins val) -- return (or set or insert after) the nth item in a list. num=size(list|attrlist|compview) -- return size of a list. compview=parent(compview) -- get parent of graphic VIEWER COMMANDS
update() -- update viewer error=save([pathstr]) -- command to save document (to pathname) compview=import(pathstr :popen :next) -- import graphic file from pathname or URL, or from a command if :popen (:next imports next in numeric series) export(compview[,compview[,...compview]] [path] :host host_str :port port_int :socket :string|:str :eps :idraw) -- remote in drawtool (or other) format compview=paste(compview [xscale yscale xoff yoff | a00,a01,a10,a11,a20,a21]) -- paste graphic into the viewer val=pastemode([val] :get) -- toggle or set paste mode, default is 0, always paste new graphics ncols() -- onscreen horizontal extent in pixels nrows() -- onscreen vertical extent in pixels dx,dy=stod(sx,sy) -- convert from screen to drawing coordinates sx,sy=dtos(dx,dy) -- convert from drawing to screen coordinates dx,dy=gtod(compview gx,gy) -- convert from graphic to drawing coordinates gx,gy=dtog(compview dx,dy) -- convert from drawing to graphic coordinates handles(flag) -- enable/disable current selection tic marks and/or highlighting highlight(compview compviewgs) -- set the highlight graphic state for a graphic zoom(zoomflt) -- zoom by factor zoomin() -- zoom-in by 2 zoomout() -- zoom-out by 2 pan(px py) -- pan viewer smallpanup() -- small pan up smallpandown() -- small pan down smallpanleft() -- small pan left smallpanright() - small pan right largepanup() -- large pan up largepandown() -- large pan down largepanleft() -- large pan left largepanright() -- large pan right gravity([flag]) -- set/get drawing editor gravity gridspacing([xsize ysize]) -- set/get drawing editor grid spacing hide(compview) -- hide graphic component show(compview) -- show graphic component desensitize(compview) -- desensitize graphic component sensitize(compview) -- desensitize graphic component IMAGING COMMANDS

-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. SEE ALSO
