Module codestream 

JPEG 2000 codestream parser and generator.

Port of ojph_codestream.h/cpp. The Codestream struct is the main entry point for encoding and decoding HTJ2K images.

Encoding workflow

1. Create a Codestream and configure parameters via access_siz_mut(), access_cod_mut(), and access_qcd_mut().
2. Call write_headers() to emit the main header to an OutfileBase implementor.
3. Push image lines with exchange().
4. Call flush() to write tile data and the EOC marker.

Decoding workflow

1. Create a Codestream and call read_headers() on an InfileBase implementor.
2. Optionally inspect SIZ/COD/QCD parameters.
3. Call create() to build internal structures.
4. Pull decoded lines with pull().
