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.

Gets or sets the minimum contrast constraint. Edge points are not created for gradients with a contrast below this value.

Gets or sets size of the 2D kernel used to convert image pixels into image gradients.

Gets or sets the minimum normalized contrast constraint. Edge points are not created for gradients with a normalized contrast below this value.

Gets or sets the length of the 1D kernel used during gradient field projection. This length is along the expected line tangent direction.

Returns the complete set of state flags supported on this object. The flags may be indexed by name as shown in the following C# code snippet: if (changedObject.StateFlags["Color"] & eventArgs.StateFlags) { ... }
