MatTElem Constructor (MatTElem, Range, NullableRange)

public Mat(
	Mat<TElem> m,
	Range rowRange,
	Nullable<Range> colRange = null
)

Public Sub New ( 
	m As Mat(Of TElem),
	rowRange As Range,
	Optional colRange As Nullable(Of Range) = Nothing
)

public:
Mat(
	Mat<TElem>^ m, 
	Range rowRange, 
	Nullable<Range> colRange = nullptr
)

new : 
        m : Mat<'TElem> * 
        rowRange : Range * 
        ?colRange : Nullable<Range> 
(* Defaults:
        let _colRange = defaultArg colRange null

Parameters

m

Type: OpenCvSharpMatTElem
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() .

rowRange

Type: OpenCvSharpRange
Range of the m rows to take. As usual, the range start is inclusive and the range end is exclusive. Use Range.All to take all the rows.

colRange (Optional)

Type: SystemNullableRange
Range of the m columns to take. Use Range.All to take all the columns.
