Antonin Descampe 275b153fc2 small changes in the INDEX-file generation (in order to only use data from index data structures) 2004-05-07 14:41:45 +00:00
Antonin Descampe a4911967eb * Fixed_quality option added : specifying -q psnr1,psnr2,psnr3,... at the 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
