SYNOPSIS

9       osage  [-(G|N|E)name=value]  [-Tlang] [-llibfile] [-ooutfile] [-O] [-P]
10       [-v] [-V] [files]

DESCRIPTION

13       osage draws clustered graphs. As input, it takes any graph in  the  dot
14       format.  It draws the graph recursively. At each level, there will be a
15       collection of nodes and a collection of cluster subgraphs.  The  inter‐
16       nals  of each cluster subgraph are laid out, then the cluster subgraphs
17       and nodes at the current level are positioned relative to  each  other,
18       treating each cluster subgraph as a node.
19
20       At each level, the nodes and cluster subgraphs are viewed as rectangles
21       to be packed together. At present, edges are  ignored  during  packing.
22       Packing  is  done  using the standard packing functions. In particular,
23       the graph attributes pack and packmode control the layout.  Each  graph
24       and  cluster can specify its own values for these attributes.  Remember
25       also that a cluster inherits  its  attribute  values  from  its  parent
26       graph.
27
28       After  all  nodes  and clusters, edges are routed based on the value of
29       the splines attribute.

OUTPUT FORMATS

32       Osage uses an extensible plugin mechanism for its output renderers,  so
33       to  see what output formats your installation of osage supports you can
34       use ``osage -Txxx'' (where xxx is an unlikely  format)  and  check  the
35       warning  message.   Also, The plugin mechanism supports multiple imple‐
36       mentations of the output formats.  To see what variants are  available,
37       use,  for  example: ``osage -Tpng:'' and to force a particular variant,
38       use, for example: ``osage -Tpng:gd''
39
40       Traditionally, osage supports the following: -Tps  (PostScript),  -Tsvg
41       -Tsvgz  (Structured  Vector  Graphics),  -Tfig  (XFIG  graphics), -Tmif
42       (FrameMaker graphics), -Thpgl (HP pen plotters),  and  -Tpcl  (Laserjet
43       printers),  -Tpng -Tgif (bitmap graphics), -Tdia (GTK+ based diagrams),
44       -Timap (imagemap files for httpd servers for each node or edge that has
45       a non‐null "href" attribute.), -Tcmapx (client‐side imagemap for use in
46       html and xhtml).  Additional less common or more special‐purpose output
47       formats   can  be  found  at  http://www.graphviz.org/cvs/doc/info/out
48       put.html.)
49
50       Alternative plugins providing support for a given output format can  be
51       found from the error message resulting from appending a ':' to the for‐
52       mat. e.g. -Tpng: The first plugin listed is always the default.
53

GRAPH FILE LANGUAGE

55       Here is a synopsis of the graph file language, traditionally using  the
56       extension .gv or .dot, for graphs:
57
58       [strict] (graph|digraph) name { statement‐list }
59       Is  the top level graph. If the graph is strict then multiple edges are
60       not allowed between the same pairs of  nodes.   If  it  is  a  directed
61       graph,  indicated by digraph, then the edgeop must be "->". If it is an
62       undirected graph then the edgeop must be "--".  Statements may be:
63
64       name=val;
65       node [name=val];
66       edge [name=val];
67       Set default graph, node, or edge attribute name to val.  Any  subgraph,
68       node, or edge appearing after this inherits the new default attributes.
69
70       n0 [name0=val0,name1=val1,...]; Creates node n0 (if it does not already
71       exist) and sets its attributes according to the optional list.
72
73       n0 edgeop n1 edgeop ... edgeop nn [name0=val0,name1=val1,...];
74       Creates edges between nodes n0, n1, ..., nn and sets  their  attributes
75       according to the optional list.  Creates nodes as necessary.
76
77       [subgraph name] { statement‐list }
78       Creates  a  subgraph.  Subgraphs may be used in place of n0, ..., nn in
79       the above statements to create edges.  [subgraph name] is optional;  if
80       missing, the subgraph is assigned an internal name.
81
82       Comments may be /*C‐like*/ or //C++‐like.
83
84
85       Attribute names and values are ordinary (C‐style) strings.  The follow‐
86       ing sections describe attributes that control graph layout.
87
88

GRAPH ATTRIBUTES

90       size="x,y" sets bounding box of drawing in inches.
91
92       page="x,y" sets the PostScript pagination unit.
93
94       ratio=f sets the aspect ratio to f which may be a floating  point  num‐
95       ber, or one of the keywords fill, compress, or auto.
96
97       pagedir=[TBLR][TBLR] sets the major and minor order of pagination.
98
99       rotate=90  sets landscape mode.  (orientation=land is backward compati‐
100       ble but obsolete.)
101
102       center=n a non‐zero value centers the drawing on the page.
103
104       layers="id:id:id:id" is a sequence of  layer  identifiers  for  overlay
105       diagrams.  The PostScript array variable layercolorseq sets the assign‐
106       ment of colors to layers. The least index is 1 and each element must be
107       a 3‐element array to be interpreted as a color coordinate.
108
109       color=colorvalue sets foreground color (bgcolor for background).
110
111       href="url"  the  default  url for image map files; in PostScript files,
112       the base URL for all relative URLs, as recognized by Acrobat  Distiller
113       3.0 and up.
114
115       URL="url" ("URL" is a synonym for "href".)
116
117       stylesheet="file.css" includes a reference to a stylesheet in -Tsvg and
118       -Tsvgz outputs.  Ignored by other formats.
119
120       splines. If set to true, edges are drawn as splines.  If set  to  poly‐
121       line,  edges  are drawn as polylines.  If set to ortho, edges are drawn
122       as orthogonal polylines.  In all of these  cases,  the  nodes  may  not
123       overlap.   If  splines=false  or  splines=line, edges are drawn as line
124       segments.  The default is false.
125
126

NODE ATTRIBUTES

128       height=d or width=d  sets  minimum  height  or  width.   Adding  fixed‐
129       size=true forces these to be the actual size (text labels are ignored).
130
131       shape=record polygon epsf builtin_polygon
132       builtin_polygon  is  one of: plaintext ellipse oval circle egg triangle
133       box diamond trapezium parallelogram  house  hexagon  octagon  note  tab
134       box3d  component.   (Polygons  are defined or modified by the following
135       node attributes: regular, peripheries, sides,  orientation,  distortion
136       and  skew.)   epsf uses the node's shapefile attribute as the path name
137       of an external EPSF file to be automatically loaded for the node shape.
138
139       label=text where text may include escaped newlines \n, \l,  or  \r  for
140       center, left, and right justified lines.  The string '\N' value will be
141       replaced by the node name.  The string '\G' value will be  replaced  by
142       the  graph  name.  Record labels may contain recursive box lists delim‐
143       ited by { | }.  Port identifiers in labels are set off by angle  brack‐
144       ets < >.  In the graph file, use colon (such as, node0:port28).
145
146       fontsize=n sets the label type size to n points.
147
148       fontname=name sets the label font family name.
149
150       color=colorvalue  sets the outline color, and the default fill color if
151       style=filled and fillcolor is not specified.
152
153       fillcolor=colorvalue sets the fill color  when  style=filled.   If  not
154       specified,  the  fillcolor when style=filled defaults to be the same as
155       the outline color.
156
157       fontcolor=colorvalue sets the label text color.
158
159       A colorvalue may be  "h,s,v"  (hue,  saturation,  brightness)  floating
160       point numbers between 0 and 1, or an X11 color name such as white black
161       red green blue yellow magenta cyan or burlywood, or a  "#rrggbb"  (red,
162       green, blue, 2 hex characters each) value.
163
164       style=filled solid dashed dotted bold invis or any Postscript code.
165
166       layer=id  or  id:id  or "all" sets the node's active layers.  The empty
167       string means no layers (invisible).
168
169       The following attributes apply only to polygon shape nodes:
170
171       regular=n if n is non‐zero then the polygon is made regular, i.e.  sym‐
172       metric  about  the  x  and  y  axis, otherwise the polygon takes on the
173       aspect ratio of the label.  builtin_polygons that are not already regu‐
174       lar  are  made  regular  by  this attribute.  builtin_polygons that are
175       already regular are not affected (i.e.  they cannot  be  made  asymmet‐
176       ric).
177
178       peripheries=n sets the number of periphery lines drawn around the poly‐
179       gon.   This  value  supersedes  the  number  of  periphery   lines   of
180       builtin_polygons.
181
182       sides=n  sets  the  number  of  sides to the polygon. n<3 results in an
183       ellipse.  This attribute is ignored by builtin_polygons.
184
185       orientation=f sets the orientation of the first  apex  of  the  polygon
186       counterclockwise  from  the  vertical, in degrees.  f may be a floating
187       point number.  The orientation  of  labels  is  not  affected  by  this
188       attribute.   This  attribute  is  added  to  the initial orientation of
189       builtin_polygons.
190
191       distortion=f sets the amount of broadening of the top and narrowing  of
192       the  bottom  of  the  polygon  (relative to its orientation).  Floating
193       point values between -1  and  +1  are  suggested.   This  attribute  is
194       ignored by builtin_polygons.
195
196       skew=f  sets  the amount of right‐displacement of the top and left‐dis‐
197       placement of the bottom of the polygon (relative to  its  orientation).
198       Floating  point values between -1 and +1 are suggested.  This attribute
199       is ignored by builtin_polygons.
200
201       href="url" sets the url for the node in imagemap,  PostScript  and  SVG
202       files.  The substrings '\N' and '\G' are substituted in the same manner
203       as for the node label attribute.  Additionally the  substring  '\L'  is
204       substituted with the node label string.
205
206       URL="url" ("URL" is a synonym for "href".)
207
208       target="target"  is  a target string for client‐side imagemaps and SVG,
209       effective when nodes have a URL.  The target string is used  to  deter‐
210       mine  which  window  of the browser is used for the URL.  Setting it to
211       "_graphviz" will open a new window if it doesn't already exist, or  re‐
212       use it if it does.  If the target string is empty, the default, then no
213       target attribute is included in the output.  The  substrings  '\N'  and
214       '\G'  are  substituted  in  the  same  manner  as  for  the  node label
215       attribute.  Additionally the substring '\L'  is  substituted  with  the
216       node label string.
217
218       tooltip="tooltip"  is  a  tooltip  string for client‐side imagemaps and
219       SVG, effective when nodes have a URL.  The tooltip string  defaults  to
220       be the same as the label string, but this attribute permits nodes with‐
221       out labels to still have tooltips thus permitting denser  graphs.   The
222       substrings  '\N' and '\G' are substituted in the same manner as for the
223       node label attribute.  Additionally the substring '\L'  is  substituted
224       with the node label string.
225
226
227

EDGE ATTRIBUTES

229       label=text  where  text  may include escaped newlines \n, \l, or \r for
230       centered, left, or right justified lines.  If  the  substring  '\T'  is
231       found  in  a  label  it will be replaced by the tail_node name.  If the
232       substring '\H' is found in a label it will be replaced by the head_node
233       name.   If  the  substring  '\E'  value  is found in a label it will be
234       replaced by: tail_node_name->head_node_name If the  substring  '\G'  is
235       found  in  a  label  it  will  be  replaced  by the graph name.  or by:
236       tail_node_name--head_node_name for undirected graphs.
237
238       fontsize=n sets the label type size to n points.
239
240       fontname=name sets the label font family name.
241
242       fontcolor=colorvalue sets the label text color.
243
244       style=solid dashed dotted bold invis
245
246       color=colorvalue sets the line color for edges.
247
248       color=colorvaluelist a ':' separated list of colorvalue creates  paral‐
249       lel edges, one edge for each color.
250
251       dir=forward back both none controls arrow direction.
252
253       tailclip,headclip=false disables endpoint shape clipping.
254
255       href="url"  sets  the  url for the node in imagemap, PostScript and SVG
256       files.  The substrings '\T', '\H', '\E' and '\G' are substituted in the
257       same  manner  as  for  the edge label attribute.  Additionally the sub‐
258       string '\L' is substituted with the edge label string.
259
260       URL="url" ("URL" is a synonym for "href".)
261
262       target="target" is a target string for client‐side imagemaps  and  SVG,
263       effective  when  edges  have a URL.  If the target string is empty, the
264       default, then no target attribute is included in the output.  The  sub‐
265       strings '\T', '\H', '\E' and '\G' are substituted in the same manner as
266       for the edge label attribute.  Additionally the substring '\L' is  sub‐
267       stituted with the edge label string.
268
269       tooltip="tooltip"  is a tooltip string for client‐side imagemaps effec‐
270       tive when edges have a URL.  The tooltip string defaults to be the same
271       as the edge label string.  The substrings '\T', '\H', '\E' and '\G' are
272       substituted in the same manner as for the edge label attribute.   Addi‐
273       tionally the substring '\L' is substituted with the edge label string.
274
275       arrowhead,arrowtail=none, normal, inv, dot, odot, invdot, invodot, tee,
276       empty, invempty, open, halfopen, diamond, odiamond, box, obox, crow.

280
281       headlabel,taillabel=string  for port labels.  labelfontcolor,labelfont‐
282       name,labelfontsize for head and  tail  labels.   The  substrings  '\T',
283       '\H',  '\E' and '\G' are substituted in the same manner as for the edge
284       label attribute.  Additionally the substring '\L' is  substituted  with
285       the edge label string.
286
287       headhref="url"  sets  the url for the head port in imagemap, PostScript
288       and SVG files.  The substrings '\T', '\H', '\E' and  '\G'  are  substi‐
289       tuted in the same manner as for the edge label attribute.  Additionally
290       the substring '\L' is substituted with the edge label string.
291
292       headURL="url" ("headURL" is a synonym for "headhref".)
293
294       headtarget="headtarget" is a target string  for  client‐side  imagemaps
295       and  SVG,  effective when edge heads have a URL.  The headtarget string
296       is used to determine which window of the browser is used for  the  URL.
297       If  the  headtarget  string  is  empty,  the  default,  then headtarget
298       defaults to the same value as target  for  the  edge.   The  substrings
299       '\T', '\H', '\E' and '\G' are substituted in the same manner as for the
300       edge label attribute.  Additionally the substring '\L'  is  substituted
301       with the edge label string.
302
303       headtooltip="tooltip"  is  a  tooltip  string for client‐side imagemaps
304       effective when head ports have a URL.  The tooltip string  defaults  to
305       be  the  same  as the headlabel string.  The substrings '\T', '\H', and
306       '\E' are  substituted  in  the  same  manner  as  for  the  edge  label
307       attribute.   Additionally  the  substring  '\L' is substituted with the
308       edge label string.
309
310       tailhref="url" sets the url for the tail port in  imagemap,  PostScript
311       and  SVG  files.   The substrings '\T', '\H', '\E' and '\G' are substi‐
312       tuted in the same manner as for the edge label attribute.  Additionally
313       the substring '\L' is substituted with the edge label string.
314
315       tailURL="url" ("tailURL" is a synonym for "tailhref".)
316
317       tailtarget="tailtarget"  is  a  target string for client‐side imagemaps
318       and SVG, effective when edge tails have a URL.  The  tailtarget  string
319       is  used  to determine which window of the browser is used for the URL.
320       If the  tailtarget  string  is  empty,  the  default,  then  tailtarget
321       defaults  to  the  same  value  as target for the edge.  The substrings
322       '\T', '\H', '\E' and '\G' are substituted in the same manner as for the
323       edge  label  attribute.  Additionally the substring '\L' is substituted
324       with the edge label string.
325
326       tailtooltip="tooltip" is a tooltip  string  for  client‐side  imagemaps
327       effective  when  tail ports have a URL.  The tooltip string defaults to
328       be the same as the taillabel string.  The substrings '\T',  '\H',  '\E'
329       and  '\G'  are  substituted  in  the  same manner as for the edge label
330       attribute.  Additionally the substring '\L'  is  substituted  with  the
331       edge label string.
332
333       labeldistance and port_label_distance set distance; also labelangle (in
334       degrees CCW)
335
336       decorate draws line from edge to label.
337
338       samehead,sametail aim edges having the same value  to  the  same  port,
339       using the average landing point.
340
341       layer=id  or  id:id  or "all" sets the edge's active layers.  The empty
342       string means no layers (invisible).
343
344
345       (neato‐specific attributes)
346       w=f sets the weight (spring constant) of an edge to the given  floating
347       point  value.   The  default  is 1.0; greater values make the edge tend
348       more toward its optimal length.
349
350       len=f sets the optimal length of an edge.  The default is 1.0.
351
