[mapserver-users] problem with zoomRectangle

[Umberto Nicoletti]

I use this code to build the zoomRectangle (note the 1 which allows
for  miny >= maxy):

return new rectObj(
                (getXAsDouble() < getX2AsDouble() ) ? getXAsDouble() :
getX2AsDouble(),
                (getYAsDouble() < getY2AsDouble() ) ? getY2AsDouble()
: getYAsDouble(),
                (getXAsDouble() < getX2AsDouble() ) ? getX2AsDouble()
: getXAsDouble(),
                (getYAsDouble() < getY2AsDouble() ) ? getYAsDouble() :
getY2AsDouble(),
                1 // image coordinates, allow for miny >= maxy
                );

where X,Y and X2,Y2 are class attributes.

HTH,
Umberto
