Method Detail

getBuffer

public ome.io.nio.PixelBuffer getBuffer(long pix)

get

public double get(ome.io.nio.PixelBuffer buf,
                  int x,
                  int y,
                  int z,
                  int c,
                  int t)

getPlane

public ome.util.PixelData getPlane(ome.io.nio.PixelBuffer buf,
                                   int z,
                                   int c,
                                   int t)

Returns the PixelData for plane given its z, c and t as well as a PixelBuffer

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
