'Usage
Dim instance As DicomImage
Dim value As Matrix
instance.UserMatrix = value
value = instance.UserMatrix
Remarks
There are multiple uses for the display matrix, with numerous matrix overrides, which all ultimately call the CoreMatrix protected function, but there could be special circumstanes where the uses wished to override the normal zoom/scroll/rotate bahaviour, and if so, then it can be done by setting this property to a non-null value.
