This tool allows you to compress or decompress TIS and MOS files provided by Infinity Engine games such as Baldur's Gate or Icewind Dale. The tool uses modern compression algorithms to achieve great compression ratios without noticeable degradation in quality.

Supported conversions:

• TIS files will be automatically compressed into the TBC format.
• TBC files will be automatically decompressed into the TIS format.
• MOS files will be automatically compressed into the MBC format.
• MBC files will be automatically decompressed into the MOS format.

A detailed description of the TBC and MBC formats can be found in FORMATS.

Usage: tileconv [options] infile [infile2 [...]]

Options:
  -e          Do not halt on errors.
  -s          Be silent.
  -v          Be verbose.
  -t type     Select pixel encoding type.
              Supported types:
                0: No pixel encoding
                1: BC1/DXT1 (Default)
                2: BC2/DXT3
                3: BC3/DXT5
  -u          Do not apply tile compression.
  -o outfile  Select output file. (Works with single input file only!)
  -z          MOS only: Decompress MBC into compressed MOS (MOSC).
  -d          Enable color dithering. (deprecated, use -q instead!)
  -q level    Specify quality vs. speed ratio when converting MBC->MOS
              or TBC->TIS. Supported levels: 0..9 (Default: 4)
              (0=fast and lower quality, 9=slow and higher quality)
              Applied level-dependent features:
                Dithering:             levels 5 to 9
                Posterization:         levels 0 to 2
                Additional techniques: levels 4 to 9
  -j num      Number of parallel jobs to speed up the conversion process.
              Valid numbers: 0 (autodetect), 1..256 (Default: 0)
  -V          Print version number and exit.

Supported input file types: TIS, MOS, TBC, MBC
Note: You can mix and match input files of each supported type.

Dependencies:

External libraries and include files are assumed to be located in the subfolders "zlib", "squish" and "pngquant". The libraries are providing their own instructions how to compile them. Afterwards call "make" to build tileconv.

If you want to change paths for the external libraries or include files, you can do so by modifying the file "config.mk" by hand.
