graphdraw - directed graph editor derived from drawtool
SYNOPSIS
graphdraw ['X-params'] [file]
DESCRIPTION
graphdraw implements a graph (node/edge) editor. graphdraw adds two new graphical objects to idraw/drawtool: an elliptical shaped node and
a directed edge represented as an arrow line. Two new tools to create these objects are provided at the bottom of the toolbar. The Node
tool (selectable by the 'N' key) takes a single mouse click and creates a new graph node at the click location. The Edge tool (selectable
by the 'E' key) lets you drag a line to create a new graph edge. If an edge is drawn from or to an existing node, it will connect itself
to the node(s) and maintain that connectivity during any later movement of nodes or edges. The Move tool will move edges or nodes, rubber-
banding the rest of the graph, and redrawing any connected edges to maintain graph connectivity and edge alignment.
Nodes contain a (initially empty) text string which can be edited by applying the Alter tool to a node. A single click on a node while on
the Alter tool will create a text cursor, possibly within an existing text string, and allow editing of the text via the usual Emacs edit-
ing commands. A click outside the text terminates editing and causes the new text to be centered within the node.
For Node and Edge objects, the Selection highlight mechanism has also been changed from the usual drawing of "handles" around a graphical
object to a red foreground color. When Nodes or Edges are selected, they turn red instead of handles being drawn around them.
graphdraw documents are saved/restored in a readable text file. Some of the tokens used in the text file are specific to graphdraw (and
possibly any program derived from graphdraw). graph drawings can be exported to other idraw/drawtool applications via the "Export Graphic"
command (under the File menu). This generates Postscript in a format that idraw can read back in, and programs like drawtool can import
via "Import Graphic" (under the file menu).
A Tools menu has been added to the set of pull-down menus to allow switching between a graph editing toolbar and a generic graphics editing
toolbar.

drawtool - idraw with extensions
SYNOPSIS
drawtool -import n ['X-params'] [file]
DESCRIPTION
drawtool is an extended version of idraw (originally from the InterViews 3.1). Based on the ivtools OverlayUnidraw library, it adds the
following features:
- double-buffered graphics drawing
- 3d Motif-like menus and buttons
- readable text save/restore
- polygon intersection and clipping tools
- graphical object attribute annotations
drawtool is derived from idraw, and implements the same set of pulldown commands and palette of toolbuttons. Read the idraw man page for
details on that part of the drawtool user interace. This page lists only the extensions to idraw embodied in drawtool.
drawtool saves and restores documents in a readable text format. This allows for manual or programmatic creation of drawtool files.
idraw-format documents can still be imported with the "Import Graphic" command, and exported with the Print command (both under the File
menu).
In addition to idraw format, the "Import Graphic" command supports the importing of encapsulated drawtool files, and the following image
file formats: TIFF, X11 Bitmap, PBM, PGM, and PPM. Compression via compress (.Z) and gzip (.gz) is recognized and handled for the script
files themselves and the PBM, PGM, and PPM image formats.
There is also support for opening (via command line or dialog box) and importing via the net (to the -import port) any arbitrary PostScript
file using the pstoedit filter, and any GIF, TIFF, or JPEG image, using respectively the giftopnm, tifftopnm, or djpeg filters.
The "Export Clipboard" command writes the contents of the clipboard out in idraw or drawtool format.
Commands have been added to the Edit menu for selecting by attributes (on the graphic objects) and clipping one polygon against another.
The View menu has been expanded with zoom and pan commands, plus commands to hide/show graphics and fix graphic sizes and locations. In
addition the viewer's panning and zooming can be chained to other viewers, and the pointer device can be put into a continuous "scribble"
mode useful when drawing multilines or polygons.
The tools have been extended with a possible six new tools: Annotate, Attribute, ClipRect, ClipPoly, ConvexHull, and GraphicLoc. Annotate
brings up a text editor in which graphic-specific text can be entered and/or edited. Attribute brings up a dialog box to create/edit prop-
erty lists for the selected graphic. ClipRect and ClipPoly clip polygons, rectangles, lines, and multilines if drawtool has been built
with the clippoly library (otherwise just lines and rectangles). ConvexHull is a convex hull drawing tool available if qhull can be found
in your path. GraphicLoc displays the coordinates of a mouse-click relative to the graphic that has been clicked on. This is relative to
the original screen coordinates of the graphic when created (or the origin of the raster if an image). Subsequent rotations and transfor-
mations can give this a non-obvious value.
OPTIONS
"-import n"
specifies the port number to run the import service on. The import service accepts connections over the net and reads drawtool or
idraw documents and pbmplus image formats (PBM/PGM/PPM), plus JPEG, GIF, TIFF, and the non-raster portions of arbitrary PostScript
if appropriate filters are available (djpeg, giftopnm, tifftopnm, pstoedit). "-color5" selects a colormap with 5 values per color
or 125 entries (5 cubed).
"-nocolor6" overrides the selection of a colormap with 6 values per color or 216 entries (6 cubed).
"-gray5" selects a colormap with 5 bits of gray-level intensity (32 gray-levels) arranged to maximize rubberband visibility.
"-gray6" selects a colormap with 6 bits of gray-level intensity (64 gray-levels) arranged to maximize rubberband visibility.
"-gray7" selects a colormap with 7 bits of gray-level intensity (128 gray-levels) arranged to maximize rubberband visibility.
"-dithermap" causes imported JPEG rasters to be mapped to the standard colormap (the default without -nocolor6) and dithered to avoid color
banding.
"-opaque_off" (or "-opoff") disables the opaque (visible) interactive transformations of graphics.
"-pagecols" (or "-ncols") sets the horizontal page extent in pixels.
"-pagerows" (or "-nrows") sets the vertical page extent in pixels.
"-panner_align tl|tc|tr|cl|c|cr|cl|bl|br|l|r|t|b|hc|vc" (or "-pal ...") selects the alignment of the panner display.
"-panner_off" (or "-poff") disables the panner display.
"-slider_off" (or "-soff") disables the slider display.
"-zoomer_off" (or "-zoff") disables the zoomer display.
"-ptrloc" enables display of the current pointer location.
"-scribble_pointer (or "-scrpt") enables continuous line drawing.
"-toolbarloc r|l" (or "-tbl ...") selects the toolbar location.
Also see "-help" and the idraw man page for more options.
