[udig-devel] shapefile renderer planning

[Jody Garnett <jody.garnett@xxxxxxxxx>]

Morning:

Shapefile renderer is moving to unsupported status now that the  
majority of speed improvement tricks have been applied to the  
streaming renderer. There is one trick remaining - that is actually  
important to us. The use of a bitmap to track which pixels have  
already been filled in - and avoid drawing multiple points; or lines;  
or polygons into the same spot ...

This trick was very important to the initial impression uDig makes  
when using road or river networks. I remember it being the major  
difference that Jesse made when competing against gvSig for speed.

Andrea is maintaining these renderers right now for geotools and would  
like to stop having to apply patches in two places. He has requested  
some feedback on the geotools-devel list and I would like to talk  
things over here and have us get back to him.
