j2000-code+doc
- The J2000 codec was written in an effort to produce the cleanest and simplest implementation possible of the JPEG-2000 standard. We have put a particular emphasis on good architecture design and code simplicity, while at the same time providing an im
jpp
- 使用了的来自www.j2000.org的开源代码，是用C写的。在WinCE上运行很慢，同时我有几个参数弄的不太明白，发上来和大家交流一下。这些代码在和www.j2000.org提供给我的代码相同的许可下发行。 VC版可以压缩和解压j2k(其实就是jp2)文件，以及Jpeg文件（使用IJG）。EVC版可以在WINCE下执行，目前EVC版只写了解码部分。 有时间请熟悉这部分的高手指导我一起完善。-use of the revenue from www.j2000.org the code i
