Class ReorderedPixelData

java.lang.Object

ome.util.PixelData

ome.io.nio.ReorderedPixelData

public class ReorderedPixelData
extends 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.

Constructor Detail

ReorderedPixelData

public ReorderedPixelData(String pixelsType,
                          ByteBuffer data,
                          int rowSize)

Default constructor.

Parameters:

pixelsType - The OME pixels type.

data - The raw pixel data.

rowSize - The size of each pixels row in bytes.

Method Detail

getReorderedPixelOffset

public static int getReorderedPixelOffset(int size,
                                          int offset,
                                          int rowSize)

Returns the re-ordered pixel offset.

Parameters:

size - The number of rows in the array.

offset - The offset within the array of rows assuming a top left origin.

rowSize - The size of each pixels row in bytes.

Returns:

See above.

getPixelValueDirect

public double getPixelValueDirect(int offset)

Returns the pixel intensity value of the pixel at a given offset within the backing buffer. This method does not take into account bytes per pixel.

Overrides:

getPixelValueDirect in class PixelData

Parameters:

offset - The absolute offset within the backing buffer.

Returns:

The intensity value.

getData

public ByteBuffer getData()

Returns the backing buffer for the pixel data.

Overrides:

getData in class PixelData

Returns:

See above.

getOrder

public ByteOrder getOrder()

Returns the byte order of the backing buffer.

Overrides:

getOrder in class PixelData

Returns:

See above.

setOrder

public void setOrder(ByteOrder order)

Set the byte order of the backing buffer.

Overrides:

setOrder in class PixelData

Parameters:

order - The byte order.
