You mean what is effectively a bitmap where the colour of each pixel represents the value stored in a 2 dimensional array ? Well potentially you could do it, but only by a lot of messing around to massage the data into an un-natural form. The only way I could see it working would be to have each row of pixels as a separate DS, and then use multiple conditional statements to map values to multiple CDEFs for colours or "Nan"s, do multiple plots to get that row of pixels in the graph - rinse and repeat for each row. It would be hard work and isn't what RRDtool is designed for. I'd suggest you'd be better with one of the other free tools that is designed for that sort of thing.
