The IDLanROI::ContainsPoints function method determines whether the given data coordinates are contained within the closed polygon region.
Result = Obj->[IDLanROI::]ContainsPoints( X [, Y [, Z]] )
The return value is a vector of values, one per provided point, indicating whether that point is contained. Valid values within this return vector include:
A point is considered to be exterior if:
A vector providing the X components of the points to be tested. If the Y and Z arguments are not specified, X must be a two-dimensional array with the leading dimension either 2 or 3 ([2,*] or [3,*]), in which case, X[0,*] represents the X values, X[1,*] represents the Y values, and X[2,*] represents the Z values.
A vector providing the Y components of the points to be tested.
A scalar or vector providing the Z component(s) of the points to be tested. If not provided, the Z components default to 0.0.
