8f3bd54c3d Changes proposed by Mathieu Malaterre from the GDCM project... Thanks a lot Mathieu 
- '//' replaced by '/* */'
- inclusion of int.h in int.c
- inclusion of j2k.h in int.h in order to export symbols
- adding (void) var when a variable is declared but not used
- some explicit cast
- CLOCKS_PER_SEC is declared as float in bcc55, so there is a need to cast it to int for the modulo operation
- some variables changed from float -> double

7ee36c3a4c 1) quantization stepsizes stored as float instead of shifted integers -> fixes a pb of precision when using very small stepsizes. 2) bug fixed when decoding until bitplane 0 -> r-value (1/2) added to the coefficient. 2005-10-27 07:49:29 +00:00

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]}

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
  }
}
