Custom renderer (beside built-in cairo based)

[drug007]

How tightly ggplotd is integrated with cairo? Could you give some advice where to start to implement custom renderer?

[BlackEdder]

It uses some of the features quite extensively and you might have most luck with making a cairo compatible interface for the custom renderer (especially cairo context). You can get a good feel for the usage by searching for 'cairo.' and 'context' in the code. Most of the code that deals with cairo directly is in source/ggplotd/ggplotd.d and source/ggplotd/geom.d

Having said that I'd be happy to include different renderer support.
