Parameters

rows

Type: SystemInt32
Number of rows in a 2D array.

cols

Type: SystemInt32
Number of columns in a 2D array.

type

Type: Emgu.CV.CvEnumDepthType
Mat element type

channels

Type: SystemInt32
Number of channels

data

Type: SystemIntPtr
Pointer to the user data. Matrix constructors that take data and step parameters do not allocate matrix data. Instead, they just initialize the matrix header that points to the specified data, which means that no data is copied. This operation is very efficient and can be used to process external data using OpenCV functions. The external data is not automatically deallocated, so you should take care of it.

step

Type: SystemInt32
Number of bytes each matrix row occupies. The value should include the padding bytes at the end of each row, if any.
