* \brief opj_dec_server is a server to decode JPT-stream and communicate locally with JPIP client, which is coded in java.
|
|
*
|
|
* \section impinst Implementing instructions
|
|
* Launch opj_dec_server from a terminal in the same machine as JPIP client image viewers. \n
|
|
* % ./opj_dec_server \n
|
|
* Keep it alive as long as image viewers are open.\n
|
|
*
|
|
* To quite the opj_dec_server, send a message "quit" through the telnet.\n
|
|
* % telnet localhost 5000\n
|
|
* quit\n
|
|
* Be sure all image viewers are closed.\n
|
|
* Cache file in JPT format is stored in the working directly before it quites.
