CSJ2K.j2k.codestream.writer.FileCodestreamWriter.writePacketBody

writePacketBody Method

writePacketBody(byte[], int, bool, bool, int)

Writes a packet body to the codestream and returns the number of bytes used by this body. If in simulation mode then no data is written to the bit stream but the number of bytes is calculated. This can be used for iterative rate allocation.

       <p>If the number of bytes that has to be written to the codestream is
       more than the space left (as returned by getMaxAvailableBytes()), only
       the data that does not exceed the allowed length is effectively written
       and the rest is discarded. However the value returned by the method is
       the total length of the packet, as if all of it was written to the bit
       stream.</p>

Declaration

public override int writePacketBody(byte[] body, int blen, bool sim, bool roiInPkt, int roiLen)

Parameters

Type	Name	Description
byte[]	body	The packet body data.
int	blen	The number of bytes in the packet body.
bool	sim	Simulation mode flag. If true nothing is written to the bit stream, but the number of bytes that would be written is returned.
bool	roiInPkt	Whether or not there is ROI information in this packet
int	roiLen	Number of byte to read in packet body to get all the ROI information

Returns

Type	Description
int	The number of bytes spent by the packet body.

Overrides
