public class BitsPerComponentBox
extends BaseJP2KBox

This class is defined to represent a Bits Per Component Box of JPEG JP2 file format. A Bits Per Component box has a length, and a fixed type of "bpcc". Its content is a byte array containing the bit depths of the color components. This box is necessary only when the bit depth are not identical for all the components.

BitsPerComponentBox

public BitsPerComponentBox(byte[] bitDepth)
Constructs a BitsPerComponentBox from the provided byte array containing the bit depths of each color component.


BitsPerComponentBox

public BitsPerComponentBox(Node node)
                    throws IIOInvalidTreeException
Constructs a BitsPerComponentBox based on the provide org.w3c.dom.Node.

Throws:
IIOInvalidTreeException
Method Detail

getNativeNode

public IIOMetadataNode getNativeNode()
Description copied from class: BaseJP2KBox
Creates an IIOMetadataNode from this box. The format of this node is defined in the XML dtd and xsd for the JP2 image file.

Specified by:
getNativeNode in interface JP2KBoxMetadata
Overrides:
getNativeNode in class BaseJP2KBox

getBitDepth

public byte[] getBitDepth()
Returns the bit depths for all the image components.


parse

protected void parse(byte[] data)
Description copied from class: BaseJP2KBox
Parses the data elements from the byte array. The subclasses should override this method and implement the proper behvaior.

Specified by:
parse in class BaseJP2KBox

compose

protected byte[] compose()
Description copied from class: BaseJP2KBox
Composes the content byte array from the data elements.

Specified by:
compose in class BaseJP2KBox
