[mapserver-users] Extract raster point values with mapserver

[William Hudspeth]

Hello,

I am running Mapserver 6.4.1, and am using Postgres/Postgis to display a 
time series of geotiff images. I would like to know the best way for a 
user to submit a given x,y coordinate pair and return the pixel value 
for a given image. Is this possible using only the mapserver api? or 
must I absolutely use mapscript?

Suggestions and examples welcome,

Thanks much
