title: doxygen not generating image files for dot
body: <p>I am trying to use doxygen to scan a C# codebase and generating class diagrams/call graphs etc. using dot. I see dot files getting genarated but no images are generated. I have tried different image formats png and jpg with no change. As a result the image links are broken when I browse the classes from html. Any idea what could be the problem?</p>
