[Mapserver-dev] GetLegendGraphic output for raster layers

[Kralidis,Tom [Burlington]]

Hi,

Issuing a GetLegendGraphic request for raster layers return blank for me
using latest CVS.

Do others agree that some sort of legend icon would be useful for raster
layers?  If yes, what is the best way to do so:

- scan all cells for RGB values (or SLD ColorMap or mapfile
classification) and generate a graduated image.  This appears to be the
CubeWerx way, i.e.:

http://demo.cubewerx.com/demo/cubeserv/cubeserv.cgi?CONFIG=main&SERVICE=
WMS&VERSION=1.1.1&REQUEST=GetLegendGraphic&LAYER=GTOPO30%3AFoundation&FO
RMAT=image%2Fpng&width=300&height=322

Of course, this would get overrided if KEYIMAGE is defined in the CLASS
object.

Cheers

..Tom
