[maplab-users] zoomrectangle and zoompoint, keeping user w/i original extents

[Charlton Purvis]

Hi, folks:

Just curious why gmap75.php3 does not include the optional fifth
parameter for zoomrectangle and zoompoint:  MaxGeoref extent (rectObj).
It's not hard to pan or zoom-out off the page w/o it.

Changing zoom*'s to read . . .
   $gpoMap->zoomrectangle($oPixelRect, $dfWidthPix,
      $dfHeightPix, $oGeorefExt,
      $gpoMap->extent);

. . . at least keeps the user in bounds.

Just a thought.
