index data structures)
2004-05-07* Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the ↵Antonin Descampe
command line when encoding an image generates layers with the corresponding psnr. You have to specify values in the increase order. This option is incompatible with "-r" or "-f" options. * Old -q option is now available with -f * The INDEX-file structure has been modified and is now like this : ------------------------------ image_width image_height progression order tile_width tile_height nb_tiles_width nb_tiles_height nb_components nb_layers nb_decompositions foreach resolution_level {[precinct_width,precinct_height]} main_header_end codestream_size foreach tile { tileno start_pos end_header end_pos squarred_error_total nb_pixels mean_squarred_error } foreach tile { foreach packet { packetno tileno layerno resno compno precinctno start_pos end_pos SE_reduction } } SE max SE total -----------------------------
