[Geomoose-users] repost: Zoom to Results (GM2)

[Dan Little]

Hey Matt,

This should not be too bad of an enhancement.  Without looking at code (because I feel you deserve SOME sort of answer immediately), I think you'd need to add the following to the query service:
1) A line checking for a "zoom_to_all" parameter.
2) You may need add something that calculates a "running" bounds.  Because MapServer doesn't natively return the bounds of all the features, you'd need to define a bounds, then while MapScript is iterating through the features, adjust those bounds to fit the features.
3) In the return/results section of the script, check to see if the zoom_to_all parameter has been set, and add the GeoMOOSE.zoomToExtent line in the <script> section that would zoom to the computed bounds from part #2.  This would look VERY similar to the zoom_to_first parameter.
