Hi, I really appreciate the integration with ditaa and org mode. http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-ditaa.html
I have an Org mode document with 5 ditaa diagrams, and exporting my Org file is taking quite a long time, about 10 seconds to compile 5 ditaa diagrams + HTML export. At the moment, even if I don't modify any of the ditaa ASCII, all 5 are compiled from ASCII to a PNG. Is there a way ask ditaa to only generate a new PNG file if the contents of the `#+BEGIN_SRC ditaa` have changed? Thanks, -- Rob
