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. ) annotationsN)IntEnum)BytesIO)Image ImageFileceZdZdZy)FormatrN)__name__ __module__ __qualname__JPEGU/var/www/html/peoplehubportal/venv/lib/python3.12/site-packages/PIL/BlpImagePlugin.pyr r *s Drr ceZdZdZdZdZy)EncodingrN)r r r UNCOMPRESSEDDXTUNCOMPRESSED_RAW_BGRArrrrr.sL CrrceZdZdZdZdZy) AlphaEncodingrrN)r r r DXT1DXT3DXT5rrrrr4s D D Drrc<|dz dzdz|dz dzdz|dzdzfS)N r?rr)is r unpack_565r%:s2 "W  "a1f_$:QX!O KKrc t|dz}ttttf}t|D]/}|dz}tjd||\}}}t |\} } } t |\} } }tdD]}tdD]}|dz}|dz }d}|dk(r| | | }}}n|dk(r| | |}}}nx|dk(r@||kDr"d| z| zdz}d| z| zdz}d| z|zdz}nL| | zdz}| | zdz}| |zdz}n3|dk(r.||kDr"d| z| zdz}d| z| zdz}d|z| zdz}nd \}}}}|r||j |g||j g2|S) E input: one "row" of data (i.e. will produce 4*width pixels) zs Y!^F ; Y[)+ >Cv*-ai%11&$D' B' Bq -A1X -(qya< "b!qA\ "b!qA\Vb[Q.Vb[Q.Vb[Q."WN"WN"WN\Vb[Q.Vb[Q.Vb[Q.%/ 1aFMM1aA,/FMM1a),? - -*-X Jrc &t|dz}ttttf}t|D]M}|dz}|||dz}tjd|}tjd|d\}}tjd|d\}t |\} } } t |\} } }tdD]}d}tdD]}d|z|zd z}||}|rd}|dz}nd }|d z}|d z}|d d|z|zzz d z}|dk(r| | | }}}nY|dk(r| | |}}}nM|d k(r"d | z| zd z}d | z| zd z}d | z|zd z}n&|d k(r!d | z| zd z}d | z| zd z}d |z| zd z}||j |gP|S)r'z<8Br?r@rAhighr$alphacode_indexrC color_coderDrErFs r decode_dxt3rSus Y"_F ; Y[)+ >Cv(,bjS38$!!%/++E5!<$$T5"5' B' Bq ,AD1X ,#$q519"2) D!GADHAR"a1q519o5= ?
