[Mapserver-dev] mapscript layerObj->bounds property or layerObj->getBounds()method

[Steve Lime]

There used to be an extent property in the layerObj that users could set
in the map file to
avoid the overhead. A method could leverage that if set.

If anything is added, it should be a getBounds() or getExtents() method

on the layerObj.  It can't be a property since setting this property
all 
the time would require opening (and sometimes scanning) the file which

can be slow sometimes.

Unfortunately it's too late for this in 4.2... even though that looks 
like a simple addition, it's this kind of "just one more last minute 
change" that introduces new issues and makes releases slip for weeks or

months.

I would suggest that you file a enhancement bug about this, and remind

us (via the bug) during the 4.3 release cycle.
