MatOfFloat6 Constructor (Int32, Int32, IntPtr, Int64) OpenCvSharp Class Library
constructor for matrix headers pointing to user-allocated data

Namespace:  OpenCvSharp.CPlusPlus
Assembly:  OpenCvSharp.CPlusPlus (in OpenCvSharp.CPlusPlus.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax

public MatOfFloat6(
	int rows,
	int cols,
	IntPtr data,
	long step = 0
)

Parameters

rows
Type: SystemInt32
Number of rows in a 2D array.
cols
Type: SystemInt32
Number of columns in a 2D array.
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 (Optional)
Type: SystemInt64
Number of bytes each matrix row occupies. The value should include the padding bytes at the end of each row, if any. If the parameter is missing (set to AUTO_STEP ), no padding is assumed and the actual step is calculated as cols*elemSize() .
