Hi Martin, as I told you in a previous mail I am trying to find a way to implement raster classification for supporting the raster symbolizer from SLD spec.
I have the following problem which I am trying to solve. During classification I might have the need to map a range (which by the way could be open on one of the two side) onto a single value (which usually is an index in a color table for palette-type images),as an instance [230.23, 259,98] --> 1 I wanted to take advantage of the categories for doing this task but I see a few problems which I think we could solve: 1>Such transformation is not allowed in actual implementation of categories but I think it really should. I tried to force the implementation to return a Constant1D transform in such case, but things do not work properly. 2>There is no way to define a range such as (a,b] or similar, where one of the extrema is not comprised. 3>We should find a way to allow users to define ranges like (-inf, a]. I tried to fix some of these issues myself but I would like to hear your opinion first.
