Hmmm my guess is he's looking for the data structure of BLPs, like the one's on wowdev wiki concerning adt, m2 and wmo structure

BLPs are a picture container, nothing more. There is no other data in this file. A BLP -> PNG converter therefore gives you all information uncompressed.

A BLP file's content can be of different compression types, nothing more.

If you really want more information (but there really isn't more except for mipmaps) read http://en.wikipedia.org/wiki/.BLP and http://wowdev.wiki/index.php?title=BLP .

The problem still is in the converter. Try a newer or different one.

Before extracting it, its also converted by some converter, d'uh.
If its correct ingame, then its correct in the file. If the file is bad after conversion, its the converter.

Have not converted a texture in months. Always used BLPConverter.
