[mapserver-users] Postprocessing images

[Lyndon Zimmermann]

Greetings mapserver users,

The Bioenergy Atlas of Australia project has a mapserver delivering a
limited amount of data, but also wants to investigate adding value to
another mapserver site by post processing the output gifs or pngs. 
Resources are not available to do the value adding (if we knew how)
server side for this "other" mapserver.  We're also interested in how
users may do the same to data delivered by us.

We are trying to map site suitability, and want to use groundwater data,
landuse, proximity to infrastructure and similar themes to do this
mapping.  We can download images from this other party's mapserver and I
was contemplating reading them with gd or the like and doing an 
if theme#1=red and theme#2=blue and buffered theme#3=black then make
outputtheme=red for each pixel, then rewriting.

Is this feasible?  Are there examples?  What are the best tools?

Regards,

Lyndon Zimmermann
