[mapserver-users] Dynamic legends

[Fernando Norte]

Hi,

I'd had a mapServer with WMS and visible by OpenLayers, in that there is a
layer to "use and occupation of the land", with several (19) types of use,
with colors detailed with class/styles.
Recently I'd make a run-time configuration filter to choose the exibition
of this type of this use.
The mapServer can be viewed here: http://globalgeosig.com.br/tizo

Now I need to filter the legend to show only the selected types, and try to
filter the legend to the only types showed at zoom level extension.
I know that this kind of legend I had been used it's not apropriate,
because it's an image only, and I know that I can make it with HTML
template. But i can't find any way to filter those data.
Someone have any ideia about how can I do this. I think this perhaps will
use mapscript (php or python) to build. There is right, or there is a
possible feature withouth use the mapscript?
I know that like the run-time filter I can 'redraw' the map through
javascript, I hope to find something similar to legends.

Thanks,
