Hi I really like the rule based renderer. One thing that doesn't seem easy though is to use the "colour" data defined property, as it isn't clear (and possibly not easy) to generate an expression for a colour.
I am thinking it would be really useful to have a "Colour" section in the function list, with at least two functions - rgb(x,y,z), and ramp(name,value) (value from 0 to 1, or 0 to 100?). Possibly one more - rgba(x,y,z,a). Then it would be very easy to build colours from data. I'm guessing this would be easy to do - any takers? or pointers to where to implement it?
