staticprivate

Get the compression parameters needed to update the coding parameters and all the pocs.

The precinct widths, heights, dx and dy for each component at each resolution will be stored as well. the last parameter of the function should be an array of pointers of size nb components, each pointer leading to an area of size 4 * max_res. The data is stored inside this area with the following pattern : dx_compi_res0 , dy_compi_res0 , w_compi_res0, h_compi_res0 , dx_compi_res1 , dy_compi_res1 , w_compi_res1, h_compi_res1 , ...

Parameters

image	the image being encoded.
p_cp	the coding parameters.
tileno	the tile index of the tile being encoded.
tileBounds	tile bounds
dx_min	minimum dx of all the components of all the resolutions for the tile.
dy_min	minimum dy of all the components of all the resolutions for the tile.
precincts	array of precincts
max_precincts	maximum number of precincts for all the bands of the tile
max_res	maximum number of resolutions for all the poc inside the tile.
componentPrecinctInfo	stores precinct exponents and precinct grid dimensions for each component
