[Geoserver-devel] GeoServer HTML ImageMap extension?

[meinc <me...@we...>]

Has anyone yet implemented a GeoServer service that is capable of producing
HTML image maps?
The only hint on the web I found is that mapbender seems to offer such a
service, where GML is translated to an HTML Image Map. However, mabpender
talks PHP, which I don't.

If no such service has yet been implemented, what would be the best way to
set it up?
Is it reasoable to realize it as a MapProducer, i.e. add a custom
GetMapProducerFactorySpi entry?

Since I've absolutely no experience with geo coordinate transformations my
main problem is
how to translate the GML coordinates into the corresponding pixel. So my
first idea was to
look at the WMS image producers that somehow renders the pixels.

What I found so far was the use of

org.geotools.renderer.lite.LiteShape2 within
org.geotools.renderer.lite.StreamingRenderer
which provides in its constructor the magic transformation, i.e.
decimator.decimateTransformGeneralize(this.geometry,this.mathTransform);

Where may I found more information on how to transform the coordinates to
pixels?
