        Parameters:
        buf - the PixelBuffer
        z - the Z
        c - the C
        t - the T
        Returns:
        the ome.util.PixelData for the plane

      • requiresPixelsPyramid

        public boolean requiresPixelsPyramid​(ome.model.core.Pixels pix)
        Returns whether a pyramid should be used for the given Pixels. This usually implies that this is a "Big image" and therefore will need tiling.
        Parameters:
        pix - the pixels
        Returns:
        true if a pyramid should be used, false otherwise
