The DjVu Reference Library does not contain the entire implementation of
|
|
the DjVu system. While it contains the entire decoder, and a big
|
|
piece of the encoder, it does not contain the sophisticated encoding
|
|
strategies necessary for reaching the highest compression ratios.
|
|
|
|
Among other things, The DjVu Reference Library contains the full DjVu
|
|
decoder, the full IW44 wavelet encoder/decoder for continuous tone
|
|
images, and the back-end of JB2 bilevel image compression technique.
|
|
However, it does not contain the code for separating document images
|
|
into foreground and background layers, nor does it contain the code of
|
|
the lossy JB2 scheme that achieves the highest compression ratios on
|
|
bitonal images.
