- Summary
---------------------------------------

A command-line tool to convert BLP image files to PNG or TGA format. The BLP
images are used by Blizzard games.

Supports the following BLP formats:

    * BLP1:
        - JPEG
        - Uncompressed without alpha channel
        - Uncompressed with alpha channel (8-bits)
    * BLP2:
        - Uncompressed without alpha channel
        - Uncompressed with alpha channel (1-, 4-, and 8-bits)
        - Uncompressed raw BGRA (known as RAW3)
        - DXT1 without alpha channel
        - DXT1 with alpha channel (1-bit)
        - DXT3 with alpha channel (4- and 8-bits)
        - DXT5 with alpha channel (8-bit)

Works on MacOS X and Linux.
