Class ReorderedPixelData

  • public class ReorderedPixelData
extends ome.util.PixelData
    Represents a block of pixel data that needs to be re-ordered in accordance with a DeltaVision file. NOTE: This buffer does not re-order the actual backing buffer so read-only buffers may be used and potential callers of getData() should be aware of this restriction.
    Since:
    3.0
