Module params 

JPEG 2000 codestream parameter marker segments (SIZ, COD, QCD, etc.)

Port of ojph_params.h, ojph_params_local.h, and ojph_params.cpp.

These types represent the marker segments that form the main header of a JPEG 2000 Part 15 (HTJ2K) codestream:

Type	Marker	Description
ParamSiz	SIZ	Image and tile size, component info
ParamCod	COD/COC	Coding style defaults / per-component
ParamQcd	QCD/QCC	Quantization defaults / per-component
ParamCap	CAP	Extended capabilities
ParamSot	SOT	Start of tile-part header
ParamTlm	TLM	Tile-part length marker
ParamNlt	NLT	Non-linearity point transformation
ParamDfs	DFS	Downsampling factor styles
CommentExchange	COM	Comment marker data

Configuration example

use openjph_core::params::{ParamSiz, ParamCod};
use openjph_core::codestream::Codestream;
use openjph_core::types::{Point, Size};

let mut cs = Codestream::new();

// Configure image geometry
cs.access_siz_mut().set_image_extent(Point::new(1920, 1080));
cs.access_siz_mut().set_num_components(3);
for c in 0..3 {
    cs.access_siz_mut().set_comp_info(c, Point::new(1, 1), 8, false);
}
cs.access_siz_mut().set_tile_size(Size::new(1920, 1080));

// Configure coding style
cs.access_cod_mut().set_num_decomposition(5);
cs.access_cod_mut().set_reversible(true);
cs.access_cod_mut().set_color_transform(true);
