This is a class used to represent PixelMemory that is resident and for which allocation and deallocation are controlled.
Inheritance Hierarchy

Namespace:  Atalasoft.Imaging.Memory
Assembly:  Atalasoft.dotImage (in Atalasoft.dotImage.dll) Version: 11.0.0.0.0.297 (.NET 4.5.2, x86)
Syntax
public abstract class ResidentPixelMemory : PixelMemory, 
	IDirectScanlineAccess

The ResidentPixelMemory type exposes the following members.

Constructors
  NameDescription
Public methodResidentPixelMemory(Int32, Int32, Int32)
Initializes a new instance of the ResidentPixelMemory class, total size in bytes is calculated by multiplying height and rowString and adding offsetToFirstScanline.
Public methodResidentPixelMemory(Int64, Int32, Int32, Int32)
Initializes a new instance of the ResidentPixelMemory class.

Methods
  NameDescription
Public methodAcquirePixelAccessor
Returns an object that inherits from PixelAccessor that is used to get to an image's pixel data.
(Inherited from PixelMemory.)
Protected methodAllocateMemory
Allocates memory for this PixelMemory object and reports it for tracking.
Public methodClone
Creates a deep copy of this image and its memory.
(Inherited from PixelMemory.)
Public methodDispose
Disposes this PixelMemory and all its managed and unmanaged resources.
(Inherited from PixelMemory.)
Protected methodDispose(Boolean)
Disposes this PixelMemory and all its managed and unmanaged resources.
(Inherited from PixelMemory.)
Protected methodDisposeManagedResources
Disposes any unmanaged resources.
(Overrides PixelMemoryDisposeManagedResources.)
Protected methodDisposeUnmanagedResources
Disposes the memory used by this object.
(Overrides PixelMemoryDisposeUnmanagedResources.)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Protected methodFinalize
Finalizes an instance of the PixelMemory class.
(Inherited from PixelMemory.)
Protected methodFreeMemory
Frees memory.
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetScanLinePtr
Gets a pointer to the a given scanline.
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Protected methodLLAllocateMemory(Int32, Boolean) Obsolete.
Subclasses of ResidentPixelMemory implement this method to allocate memory.
Protected methodLLAllocateMemory(Int64, Boolean)
Subclasses of ResidentPixelMemory implement this method to allocate memory.
Protected methodLLClone
Subclasses of PixelMemory implement this method to create a deep copy of the object.
(Inherited from PixelMemory.)
Protected methodLLFreeMemory
Subclasses of ResidentPixelMemory implement this method to free memory.
Protected methodLLGetHeight
Returns the height of the image.
(Overrides PixelMemoryLLGetHeight.)
Protected methodLLGetPixelAccessor
Returns a suitable PixelAccesor object for this PixelMemory.
(Overrides PixelMemoryLLGetPixelAccessor.)
Protected methodLLGetRowStride
Returns the size of a scanline in bytes, rounded up to the next multiple of 4.
(Overrides PixelMemoryLLGetRowStride.)
Protected methodLLLock
Subclasses of PixelMemory implement this method to lock the memory.
