[mapguide-users] Map Extents

I suspected that might be the case since the documentation says:

GetMapHeight() 
Returns the height of the current map, expressed in map units. 

I wasn't sure if current map meant the underlying map extents or the current
map view.

Unfortunately GetMapWidth() and GetMapHeight() return the full extent of the
map, not the current view extent.

We need to add an API for that, as you suggested.

Juan, does your application need to run with both viewers? For the AJAX
viewer you can grab the variables extX1, extY1, extX2 and extY2 (in
mapFrame) which represent the coordinates of the current view. For the DWF
viewer there is an API to get the bounds of the current view.

Using the viewer API, could you use a combination of GetCenter() and
GetMapWidth() and GetMapHeight() and then calculate it?  It would be nice if
there was a GetMapBounds() or something that returned an array of the 4
corner coordinates.

Sorry if this is a repost, but I didn't see it appear in the list.  
Something is going on with my email system here at work.

 Has anyone been able to grab the CURRENT map extent of the map window?

I've tried multiple ways, but it comes back with the full extent of the
map
each time and not getting the current coordinates.   Any help is
appreciated.
