# Grey Morphology

Choose the Operation you want the tool to perform. The edit control lets you add any of the predefined POneImageMorphology3x3ElementTypeConstants. If you have more than one kernel specified, the tool constructs a composite structuring element. You specify the origin of the composite element using the Origin X and Origin Y controls. The Composite Size text label displays the size of the composite element.

If you choose a custom structuring element, the tab allows you to configure your own structuring element with the following feature:

Checking a particular MemberMask sets the property for that location in the structuring element to true. While enabled, you can set the GetMemberValue for that location.
