SID-02403: DirectedGraph not rendering

Status:	Asked	TWiki version:	6.0.2	Perl version:	v5.14.1
Category:	DirectedGraphPlugin	Server OS:	Red Hat Enterprise Linux Server release 6.9 (Santiago)	Last update:	6 years ago

We tried to install graphviz via instruction at http://www.linuxfromscratch.org/blfs/view/svn/general/graphviz.html but getting the following error message instead of the graph

DirectedGraph Error (127):

Processing /usr/bin/.convert -density %DENSITY|N% -geometry %GEOMETRY|S% %INFILE|F% %OUTFILE|F%

We have the following code:

|  <dot antialias="on" size="800x800">
  digraph GRS {
  fontsize=8;
  nodesep=0.5;
  RESET [shape=none label="~Cpl_PC6PWROK or\nWarmReset"];
  IDLE [label="Idle(1)\nExitCnt=63"];
  FUSE [label="Fuse(3)\nExitCnt=23"];

I am not familiar with this plugin, but reading the docs and code, add a DIRECTEDGRAPHPLUGIN_DEBUG setting in your Main.TWikiPreferences, and see generated temp files in /tmp. Look also at the twiki/data/debug.txt

Hello Peter,

We added DIRECTEDGRAPHPLUGIN_DEBUG setting in your TWikiPreferences and below message getting in twiki/data/debug.txt but there is no temp files generated in /tmp.

Per article https://foswiki.org/Extensions/DirectedGraphPlugin

Verified installation using below steps: Ensure that the dot command can manually generate a png file. From a command prompt, enter dot -v Then ^c and examine the output. You should see png as a listed device, and can confirm that textlayout uses cairo.

Result: dot - graphviz version 2.40.1 (20161225.0304) libdir = "/usr/local/lib/graphviz" Activated plugin library: libgvplugin_dot_layout.so.6 Using layout: dot:dot_layout Activated plugin library: libgvplugin_core.so.6 Using render: dot:core Using device: dot:dot:core The plugin configuration file: /usr/local/lib/graphviz/config6 was successfully loaded. render : dot dot_json fig json json0 map mp pic pov ps svg tk vml xdot xdot_json layout : circo dot fdp neato nop nop1 nop2 osage patchwork sfdp twopi textlayout : device : canon cmap cmapx cmapx_np dot dot_json eps fig gv imap imap_np ismap json json0 mp pic plain plain-ext pov ps ps2 svg svgz tk vml vmlz xdot xdot1.2 xdot1.4 xdot_json loadimage : (lib) eps gif jpe jpeg jpg png ps svg

NOTE: png is not listed under device instead of I can see in loadimage. Is something need to change?

If using the antialias option, ensure that ImageMagic convert command can convert from a .ps to .png format.

We configured as Set DIRECTEDGRAPHPLUGIN_ANTIALIAS = off

Can you please help here.
