Converting Graphviz dot file to image file using dot utility

OpenBiomind generates a Graphviz dot file as an output of GraphFeatures task. In the GUI, we thought to provide a image of the graph too. This was simply achieved using the dot utility provided by Graphviz.

Following snippet shows a sample usage (working example can be seen in this snippet was modified from revision 46 of GraphFeaturesWizard):
<br />// final String graphvizDotUtilityPath = ...<br />// final String imageType = ... // "png", "gif", or other supported type<br />// final String sourceDotFilePath = ...<br />// final String outputImageFilePath = ...<br /><br />final List<String> commandList = new ArrayList<String>();<br />commandList.add(graphvizDotUtilityPath);<br />commandList.add("-T" + imageType);<br />commandList.add(sourceDotFilePath);<br />commandList.add("-o" + outputImageFilePath);<br /><br />// java.lang.Process<br />// java.lang.ProcessBuilder<br />final Process process = new ProcessBuilder(commandList).start();<br />
Following is the snapshot of a workbench after opening the graph (image):
