Here's another revision, still the same problem. Not yet getting something
crucial:
_Mins = []
_Maxs = []
function (__structure min, __structure max) main (__structure Points)
{
var result = new Object()
if (Points != null) {
for (var i=0; i < Points.length; ++i) {
_Mins = [Math.min(Points[0][0], Points[i][0]),
Math.min(Points[0][1], Points[i][1])];
}
for (var j=0; j < Points.length; ++j) {
_Maxs = [Math.max(Points[0][0], Points[j][0]),
Math.max(Points[0][1], Points[j][1])];
}
}
result.min = _Mins;
result.max = _Maxs;
return result
}
