Methods

	Name	Description
	AcquireNextScanline	Acquires the next scanline in sequence for this image.
	AcquirePreviousScanline	Acquires the previous scanline in the image.
	AcquireScanline	Aquires a scanline of data for accessing.
	Dispose	Disposes this PixelAccessor and all its managed and unmanaged resources.
	Dispose(Boolean)	Disposes this PixelAccessor and all its managed and unmanaged resources.
	DisposeManagedResources	Disposed any managed objects that implement IDisposable
	DisposeUnmanagedResources	Disposes any unmanaged resources such as memory.
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Finalize	Finalizes an instance of the PixelAccessor class. (Overrides ObjectFinalize.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetReadOnlyColumn	Gets the read only column.
	GetReadOnlyColumnSection	Gets the read only column section.
	GetReadOnlyScanline(Int32)	Gets the contents of a scanline, allocating memory for the data.
	GetReadOnlyScanline(Int32, Byte)	Copies the contents of a scanline into the supplied array
	GetReadOnlyScanlineSection	Gets the read only scanline section.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	LLAcquireScanline	Subclasses of PixelAccessor implement this method to acquire a pointer to a scanline.
	LLReleaseScanline	Subclasses of PixelAccessor implement this method to release a previously acquired scanline
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	NotifyAccessorReleased	This method is called whenever an accessor has been released.
	NotifyAccessorReleasing	This method is called when a PixelAccessor is about to be released.
	Release	Releases a PixelAccessor back to the PixelMemory object that owns it.
	ReleaseScanline	Releases the last scanline acquired.
	Reset	Resets the pixel accessor so that AcquireNextScanline will acquire the first scanline in the image.
	ToString	Returns a string that represents the current object. (Inherited from Object.)
	WriteColumn	Writes the column.
	WriteColumnSection	Writes the column section.
	WriteToScanline	Writes to scanline.
