Method	Description
Clone	Creates a shallow copy of the current Filter. (Inherited from Filter)
ColorMatrixFilter	Initializes a new instance of ColorMatrixFilter.
CopyMatrix	Copies the ColorMatrix of the ColorMatrixFilter to another ColorMatrix.
Equals	Overloaded. Compares two objects to determine if they are equal. (Inherited from Object)
GetHashCode	Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
ReferenceEquals	Determines whether the specified Object instances are the same instance. (Inherited from Object)
