33 @brief JPT-stream reader (JPEG 2000, JPIP)
35 JPT-stream functions are implemented in J2K.C.
39 Message Header JPT stream structure
41 typedef struct opj_jpt_msg_header {
42 /** In-class Identifier */
44 /** Last byte information */
45 unsigned int last_byte;

47 unsigned int Class_Id;

53 unsigned int Msg_length;
54 /** Auxiliary for JPP case */
55 unsigned int Layer_nb;
56 } opj_jpt_msg_header_t;

61 Initialize the value of the message header structure
62 @param header Message header structure
64 void jpt_init_msg_header(opj_jpt_msg_header_t * header);
67 Read the message header for a JPP/JPT - stream
68 @param cinfo Codec context info
70 @param header Message header structure
72 void jpt_read_msg_header(opj_common_ptr cinfo, opj_cio_t *cio, opj_jpt_msg_header_t *header);
