IMcRegionAccessUnlockPixelPointer Method

Sub UnlockPixelPointer

Occasionally in makes sense to keep an McRegionAccess instance alive (by not fully releasing it) during periods when you are not using it to access pixel data. This makes sense when the McRegionAccess has been created with a Type property that required a cast from the underlying McImage.Type. It is never worthwhile doing this if the McRegionAccess Type is the same as the underlying McImage.Type, since in this case it is very inexpensive to instantiate a new McRegionAccess instance. However, if you know that you may need the cast pixel data again, then it may be worthwhile to keep the cast McRegionAccess instance alive holding the cast pixels rather than needing to do the cast again later. If an McRegionAccess is kept alive across periods where it is not being actively used, then you should call this method to unlock the pixel data. This unlocking allows the cast pixel data to be swapped out as necessary for memory management.
