[graphviz plugin]not pdf output

[sacl]

Hi everybody ...

OS
Wheezy 7.0 - Debian 3.2.35-2 x86_64 GNU/Linux
dokuwiki Version: 0.0.20120125b-2
graphviz 2.26.3-12

PLUGINS
dw2pdf - 2012-05-20
graphviz 2010-11-24

PROBLEM

1. Graphviz works excellent.
2. Dw2pdf works excellent.
3. when exporting to PDF, so good even images.
4. But the graphics generated by graphviz ... NOT.
5. I made with colored and colorless. Just are not included in the PDF.

CODE EXAMPLE

Digraph R
{
/* Configuración general*/
rotate="90";
size="6,10";
bgcolor=transparent;

/* Configuración nodos */
Reclamo [color="skyblue",style=filled];
Contener [shape=box];
Solucionado [shape=diamond, label="¿Solucionado?"];
Registrar [shape=box];
Evaluar [shape=box, label="Evaluar Méritos, Investigar"];
Valido [shape=diamond, label="¿Proceso Válido?"];
Informe [shape=box, label="Generar informe Técnico"];
Responder [shape=box, label="Responder al Paciente o Médico"];
Archivar [shape=box];
Fin [color="skyblue",style=filled];

SiSolucion [shape=circle,label="Sí",height=.4,fixedsize=true,color="green",style=filled];
NoSolucion [shape=circle,label="No",height=.4,fixedsize=true,color="red",style=filled];
SiValido [shape=circle,label="Sí",height=.4,fixedsize=true,color="green",style=filled];
NoValido [shape=circle,label="No",height=.4,fixedsize=true,color="red",style=filled];

/* Código */
Reclamo -> Contener -> Solucionado;
Solucionado -> NoSolucion -> Registrar -> Evaluar;
Evaluar -> Valido -> SiValido -> Informe;
Informe -> Responder -> Archivar;
Archivar -> Fin;
Solucionado -> SiSolucion -> Fin;
Valido -> NoValido -> Responder;
}

In advance, thanks for any help.

i guess this plugin needs a specialized render mode to return valid image html understandable for the pdfrenderer.

But maybe it is simpler, and needs the print mode of the plugin some improvement (do the browser show the correct Print preview).
Please ask the plugin author to improve it.

Some dw2pdf specific work in graphviz is done in this PR splitbrain/dokuwiki-plugin-graphviz#14

Solution is based at creating file on the server which is included in the created pdf.

With current understanding this issue has to be solved by the graphviz plugin.
