BLP1 files, used mostly in Warcraft III, are not fully supported.
|
|||
|
|
All types of BLP2 files used in World of Warcraft are supported.
|
|||
|
|
|
|||
|
|
The BLP file structure consists of a header, up to 16 mipmaps of the
|
|||
|
|
texture
|
|||
|
|
|
|||
|
|
Texture sizes must be powers of two, though the two dimensions do
|
|||
|
|
not have to be equal; 512x256 is valid, but 512x200 is not.
|
|||
|
|
The first mipmap (mipmap #0) is the full size image; each subsequent
|
|||
|
|
mipmap halves both dimensions. The final mipmap should be 1x1.
|
|||
|
|
|
|||
|
|
BLP files come in many different flavours:
|
|||
|
|
* JPEG-compressed (type == 0) - only supported for BLP1.
|
|||
|
|
* RAW images (type == 1, encoding == 1). Each mipmap is stored as an
|
|||
|
|
array of 8-bit values, one per pixel, left to right, top to bottom.
|
|||
|
|
Each value is an index to the palette.
|
|||
|
|
* DXT-compressed (type == 1, encoding == 2):
|
|||
|
|
- DXT1 compression is used if alpha_encoding == 0.
|
|||
|
|
- An additional alpha bit is used if alpha_depth == 1.
|
|||
|
|
- DXT3 compression is used if alpha_encoding == 1.
|
|||
|
|
- DXT5 compression is used if alpha_encoding == 7.
