Method Detail

readBox

public boolean readBox()
                throws java.io.IOException

Description copied from class: JP2Box

Reads the box, putting appropriate information in the RepInfo object. setModule, setBoxHeader, setRepInfo and setDataInputStream must be called before readBox is called. Thus, the header of the box must already have been read. 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. The number of bytes read must be placed in _bytesRead.

Specified by:

readBox in class JP2Box

Throws:

java.io.IOException
