Description
OpenJPEG already has some JNI based Java bindings that it would be worthwhile to test. Preliminary results:
OpenJPEGJavaEncoder.encodeImageToJ2K: (re-)allocating 65536 bytes for the compressedStream Encoder additional arguments = -n 1 tile number 1 / 1 - tile encoded in 0.003493 s compression time = 8 msec Encode time: 9 Stream length: 65536 Library stated stream length: 236 C: after opj_encode_with_info
