CudaMem Class

OpenCvSharp Class Library

CudaMem is limited cv::Mat with page locked memory allocation.

Inheritance Hierarchy

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

Syntax

public sealed class CudaMem : DisposableGpuObject, 
	ICloneable

Public NotInheritable Class CudaMem
	Inherits DisposableGpuObject
	Implements ICloneable

public ref class CudaMem sealed : public DisposableGpuObject, 
	ICloneable

[<SealedAttribute>]
type CudaMem =  
    class
        inherit DisposableGpuObject
        interface ICloneable
    end

The CudaMem type exposes the following members.

Constructors

	Name	Description
	CudaMem	Creates empty CudaMem
	CudaMem(IntPtr)	Creates from native cv::gpu::CudaMem* pointer
	CudaMem(CudaMem)	Initializes a new instance of the CudaMem class
	CudaMem(Size, MatType, CudaMemAllocType)	Initializes a new instance of the CudaMem class
	CudaMem(Int32, Int32, MatType, CudaMemAllocType)	Initializes a new instance of the CudaMem class

Properties

	Name	Description
	AllocType
	Cols	the number of columns
	CvPtr	Native pointer of OpenCV structure (Inherited from DisposableCvObject.)
	Data	pointer to the data
	DataEnd	helper fields used in locateROI and adjustROI
	DataStart	helper fields used in locateROI and adjustROI
	Flags	includes several bit-fields: 1.the magic signature 2.continuity flag 3.depth 4.number of channels
	Height	the number of rows
	IsDisposed	Gets a value indicating whether this instance has been disposed. (Inherited from DisposableObject.)
	IsEnabledDispose	Gets or sets a value indicating whether you permit disposing this instance. (Inherited from DisposableObject.)
	RefCount	pointer to the reference counter; when matrix points to user-allocated data, the pointer is NULL
	Rows	the number of rows
	Width	the number of columns

Methods

	Name	Description
	AssignTo
	CanMapHostMemory	returns if host memory can be mapperd to gpu address space;
	Channels	Returns the number of matrix channels.
	Clone	returns deep copy of the matrix, i.e. the data is copied
	Create	allocates new matrix data unless the matrix already has specified size and type.
	CreateGpuMatHeader	maps host memory into device address space and returns GpuMat header for it. Throws exception if not supported by hardware.
	CreateMatHeader	returns matrix header with disabled reference counting for CudaMem data.
	Depth	Returns the depth of a matrix element.
	Dispose	Releases the resources (Inherited from DisposableObject.)
	ElemSize	Returns the matrix element size in bytes.
	ElemSize1	Returns the size of each matrix element channel in bytes.
	Empty	returns true if GpuMatrix data is NULL
	Equals	(Inherited from Object.)
	GetHashCode	(Inherited from Object.)
	GetType	(Inherited from Object.)
	IsContinuous	returns true iff the GpuMatrix data is continuous (i.e. when there are no gaps between successive rows). similar to CV_IS_GpuMat_CONT(cvGpuMat->type)
	Release	Clean up any resources being used.
	Size	Returns a matrix size.
	Step	a distance between successive rows in bytes; includes the gap if any
	Step1	Returns a normalized step.
	ThrowIfDisposed	If this object is disposed, then ObjectDisposedException is thrown. (Inherited from DisposableObject.)
	ToString	(Inherited from Object.)
	Type	Returns the type of a matrix element.

Operators

	Name	Description
	(CudaMem to Mat)	returns matrix header with disabled reference counting for CudaMem data.
	(CudaMem to GpuMat)	maps host memory into device address space and returns GpuMat header for it. Throws exception if not supported by hardware.
