The CogImage8Grey type exposes the following members.

Constructors

	Name	Description
	CogImage8Grey	Constructs a new instance of this class.
	CogImage8Grey(Bitmap)	Constructs a CogImage8Grey, copying or computing the pixels from the given bitmap.
	CogImage8Grey(IntPtr)	Constructs a new instance of this class using com pointer.
	CogImage8Grey(CogImage8Grey)	Constructs a new instance of this class as a deep copy of the given instance.
	CogImage8Grey(Int32, Int32)	Constructs a CogImage8Grey, allocating image memory with the given width and height.

Methods

	Name	Description
	Allocate	Initialize the image with (undefined) pixel data of the given width and height. This method may not be called more than once.
	Clone	Returns a deep copy of this class instance. Derived classes that implement Clone should override this method; other clients who wish to clone this instance should call ICloneable.Clone. See also CogSerializer.DeepCopyObject
	Copy	Create a copy of this image in a new image. While the pixels will be copied, the CoordinateSpaceTree and PixelFromRootTransform will be shared.
	Copy(CogImageCopyModeConstants)	Create a copy of this image in a new image. Pixels may be shared between images by specifying CopyMode=cogImageCopyModeSharePixels.
	CopyBase	Create a copy of this image in a new image. Pixels may be shared between images by specifying CopyMode=cogImageCopyModeSharePixels.
	CreateObjRef	Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object. (Inherited from MarshalByRefObject.)
	Dispose
	Dispose(Boolean)
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	(Overrides Object Finalize .)
	Get8GreyPixelMemory	Gets an object that can be used to directly access pixel memory. The caller MUST call Dispose on this object when finished with it.
	GetAttributes	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetClassName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetComponentName	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetConverter	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultEvent	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetDefaultProperty	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEditor	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetEvents( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetLifetimeService	Retrieves the current lifetime service object that controls the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	GetObjectData
	GetPixel	Pixel value at given location.
	GetProperties	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetProperties( Attribute )	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetPropertyOwner	Implements the corresponding member of the ICustomTypeDescriptor interface. May be overridden in derived classes to provide custom type information. (Inherited from CogObjectBase.)
	GetRoot	Returns the root image object that contains the raw pixel data.
	GetTransform	Returns a transform that maps points from the 'From' coordinate space to the 'To' space. The special string "." is accepted as an alias for the SelectedSpaceName of this image.
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	InitializeLifetimeService	Obtains a lifetime service object to control the lifetime policy for this instance. (Inherited from MarshalByRefObject.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	MemberwiseClone(Boolean)	Creates a shallow copy of the current MarshalByRefObject object. (Inherited from MarshalByRefObject.)
	ResumeAndRaiseChangedEvent	Re-enables raising of the Changed event after SuspendChangedEvent has been called. Also raises the Changed event if the ChangedEventSuspended count is reduced to zero and any changes were made while events were suspended. Must be called once for each call to SuspendChangedEvent.
	ScaleImage	Creates a scaled version of this image. The dimensions of the returned image (in pixels) are specified by the width and height arguments. The scaling is performed using bilinear interpolation.
	SetPixel	Pixel value at given location.
	SetRoot	Sets the root image object that contains the raw pixel data.
	SuspendChangedEvent	Temporarily suspends the raising of the Changed event. May be called more than once, and a corresponding call to ResumeAndRaiseChangedEvent must be made for each call to SuspendChangedEvent.
	ToBitmap	Creates a 24-bit RGB Windows bitmap from this image.
	ToString	Returns a String that represents the current Object. (Inherited from Object.)

Fields

	Name	Description
	SfCoordinateSpaceTree	This bit will be set in the EventArgs of a Changed event every time the value returned by CoordinateSpaceTree may have changed.
	SfPixelFromRootTransform	This bit will be set in the EventArgs of a Changed event every time the value returned by PixelFromRootTransform may have changed.
	SfSelectedSpaceName	This bit will be set in the EventArgs of a Changed event every time the value returned by SelectedSpaceName may have changed.

Properties

	Name	Description
	Allocated	Whether there is pixel data associated with this image.
	ChangedEventSuspended	If nonzero, indicates that the raising of the Changed event has been suspended. This value is incremented when SuspendChangedEvent is called and decremented when ResumeAndRaiseChangedEvent is called.
	CoordinateSpaceTree	Returns/sets the tree of all named coordinate spaces for this image. The tree provides advanced functions for managing coordinate spaces.
	HasChanged	If true, the serializable state of this object has changed since the last time it was serialized.
	Height	Height of the image.
	PixelFromRootTransform	Transformation that maps points into pixel space ("#") from the root space ("@").
	SelectedSpaceName	Returns/sets the name of the coordinate space to be used by tools which process this image.
	Width	Width of the image.

Events

	Name	Description
	Changed	Occurs when one or more parts of the object's state may have changed.
