Property Value
Type: IPictureDisp
Remarks
The mask image determines what parts of the button image are transparent.
When you create an image that you plan on using as a mask image, all of the areas that you want to be transparent should be white, and all of the areas that you want to show should be black.
Always set the mask after you have set the picture for a CommandBarButton object.
