Syntax

public MatOfPoint(
	MatOfPoint m,
	Rect roi
)

Public Sub New ( 
	m As MatOfPoint,
	roi As Rect
)

public:
MatOfPoint(
	MatOfPoint^ m, 
	Rect roi
)

new : 
        m : MatOfPoint * 
        roi : Rect -> MatOfPoint

m: Type: OpenCvSharp.CPlusPlusMatOfPoint
Array that (as a whole or partly) is assigned to the constructed matrix. No data is copied by these constructors. Instead, the header pointing to m data or its sub-array is constructed and associated with it. The reference counter, if any, is incremented. So, when you modify the matrix formed using such a constructor, you also modify the corresponding elements of m . If you want to have an independent copy of the sub-array, use Mat.Clone() .
roi: Type: OpenCvSharp.CPlusPlusRect
Region of interest.
