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.

The number of care pixels in the region of interest. Note that this value is always less than or equal to NumRegionBoundingBoxPixels.

The number of pixels in the pixel aligned bounding box of the region of interest.

The number of pixels that were actually used by the tool or function to compute the result. Such pixels must always be visible care pixels, but some functions may choose to impose other restrictions as well. Each function should document how it computes NumUsedPels. Note that this value is always less than or equal to NumVisibleCarePels.

The number of pixels in the effective source region that are both care pixels and visible pixels. Note that this value is always less than or equal to NumCarePels.

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) { ... }
