如果没有任何Java库可以编码djvu,那么在尝试实现它时可能会出现什么样的潜在困难?

最佳答案

DjVu 文件格式是开放的,但完整的引用编码器不是标准的一部分:

DjVu is an open standard. The file format specification, as well as an open source implementations of the decoder (and part of the encoder) are available.

这是由于专利:

Several patents apply to two very specific aspects of DjVu and DjVuLibre. The patents cover a particular aspect of the ZP-coder (the arithmetic coder used in DjVu and implemented in libdjvu/ZPCodec.cpp) and the background masking technique used in the IW44 wavelet encoder (implemented in libdjvu/IW44EncodeCodec.cpp).

有一个outdated GhostScript to DjVu converter ,可以作为编码器引用。
