NAME

       gvmap.sh - pipeline for running gvmap

SYNOPSIS

       gvmap.sh [-vV?]	[ options ] [ -o outfile ] [ files ]

DESCRIPTION

       gvmap.sh  takes	as input a graph in DOT format, performs a layout, runs the output through gvmap and renders the output. At some point, it
       is hoped to integrate all of these tasks into gvmap.

OPTIONS

       The following options are supported:

       -a k   The integer k specifies the average number of artificial points added along the bounding box of the labels. Such	artificial  points
	      are  added  to  avoid a country boundary cutting through the boundary box of the labels. Computing time is proportional to k; hence,
	      for large graphs, a small value of k is suggested. If k = -1, a suitable value of k is automatically selected  based  on	the  graph
	      size. By default k = -1.

       -K layout
	      specifies  which	program  should  be use for the initial layout. By default, sfdp is run. Also by default, the layout is passed the
	      flag -Goverlap=prism. This can be overridden using a -g flag.

       -T format
	      specifies the final output format. This works the same way as the -T flag for any Graphviz layout program.

       -N attr=val
	      specifies the setting of a default node attribute during the rendering phase. This works the  same  way  as  the	-N  flag  for  any
	      Graphviz layout program.

       -G attr=val
	      specifies  the setting of a graph attribute during the rendering phase. This works the same way as the -G flag for any Graphviz lay-
	      out program.

       -E attr=val
	      specifies the setting of a default edge attribute during the rendering phase. This works the  same  way  as  the	-E  flag  for  any
	      Graphviz layout program.

       -n attr=val
	      specifies  the  setting of a default node attribute during the layout phase. This works the same way as the -N flag for any Graphviz
	      layout program.

       -g attr=val
	      specifies the setting of a graph attribute during the layout phase. This works the same way as the -G flag for any  Graphviz  layout
	      program.

       -e attr=val
	      specifies  the  setting of a default edge attribute during the layout phase. This works the same way as the -E flag for any Graphviz
	      layout program.

       -A flag
	      specifies a flag to be passed to gvmap. For example, gvmap.sh -Ae -As3 causes gvmap -e -s3 to be run.

       -v     Set verbose mode.

       -V     Print version information and exit.

       -?     Print usage information and exit.

EXAMPLES

       The following invocation creates a map with edges in semi-transparent light gray and nodes laid out using sfdp:

       gvmap.sh -Ae -Ecolor=#55555522 -Tpng foo.gv > foo.png

       It is equivalent to running the pipeline

       sfdp -Goverlap=prism foo.gv | gvmap -e | neato -n2 -Ecolor=#55555522 -Tpng > foo.png

NAME

       libgvc - Graphviz context library

SYNOPSIS

       #include <graphviz/gvc.h>

       /* set up a graphviz context */
       extern GVC_t *gvNEWcontext(char **info, char *user);
       extern char *gvUsername(void);

       /*  set up a graphviz context - alternative */
       /*     (wraps the above two functions using info built into libgvc) */
       extern GVC_t *gvContext(void);

       /* parse command line args - minimally argv[0] sets layout engine */
       extern int gvParseArgs(GVC_t *gvc, int argc, char **argv);
       extern graph_t *gvNextInputGraph(GVC_t *gvc);

       /* Compute a layout using a specified engine */
       extern int gvLayout(GVC_t *gvc, graph_t *g, char *engine);

       /* Compute a layout using layout engine from command line args */
       extern int gvLayoutJobs(GVC_t *gvc, graph_t *g);

       /* Render layout into string attributes of the graph */
       extern void attach_attrs(graph_t *g);

       /* Parse an html string */
       extern char *agstrdup_html(char *s);
       extern int aghtmlstr(char *s);

       /* Render layout in a specified format to an open FILE */
       extern int gvRender(GVC_t *gvc, graph_t *g, char *format, FILE *out);

       /* Render layout in a specified format to an open FILE */
       extern int gvRenderFilename(GVC_t *gvc, graph_t *g, char *format, char *filename);

       /* Render layout according to -T and -o options found by gvParseArgs */
       extern int gvRenderJobs(GVC_t *gvc, graph_t *g);

       /* Clean up layout data structures - layouts are not nestable (yet) */
       extern int gvFreeLayout(GVC_t *gvc, graph_t *g);

       /* Clean up graphviz context */
       extern int gvFreeContext(GVC_t *gvc);

DESCRIPTION

       libgvc  provides  a context for applications wishing to manipulate and render graphs.  It provides a command line parsing, common rendering
       code, and a plugin mechanism for renderers.
