Constructor Detail

CompositionBox

public CompositionBox(java.io.RandomAccessFile raf,
                      BoxHolder parent)

Constructor with superbox.

Parameters:

parent - parent superbox of this box

Method Detail

readBox

public boolean readBox()
                throws java.io.IOException

Reads the box, putting appropriate information in the RepInfo object. setModule, setBoxHeader, setRepInfo and setDataInputStream must be called before readBox is called. readBox must completely consume the box, so that the next byte to be read by the DataInputStream is the FF byte of the next Box.

Specified by:

readBox in class JP2Box

Throws:

java.io.IOException

addInstSet

protected void addInstSet(Property p)

Add an instruction set property to the list. This is called from InstructionSetBox.

setHeight

protected void setHeight(long h)

Set the height value. This is called from CompositionBox.

setWidth

protected void setWidth(long w)

Set the height value. This is called from CompositionBox.

setLoop

protected void setLoop(int l)

Set the loop value. This is called from CompositionBox.
