[OSGeo-Discuss] Generating html clickable image maps from polygons

Hi list,

A rather technical question. I was able to find a potential solution 
with GRASS GIS, but want to know if there are other solutions involving 
FOSS4G software.

Which other FOSS4G software can generate html clickable image maps out 
of polygons? The challenge is simple: a colleague has many polygons that 
must be exported to several clickable PNGs like the example on this 
page: http://www.weatheroffice.gc.ca/warnings/sqc_e.html
(A webmap tool such as OpenLayers would be much more powerful, but in 
some cases we do need clickable PNGs.)

I found out it seems GRASS GIS 6.3+ can do it via its HTMLMAP driver:
Can any other OSGeo software do the same?

Thanks for any reply!
