Companion to --validate-png — validates BLP textures without paying
the DXT decompress cost. Useful for spot-checking thousands of BLPs
in an extract dir:
wowee_editor --validate-blp Texture.blp
BLP: Texture.blp
magic : BLP2
size : 128 x 128
valid mips : 8
file bytes : 23044
PASSED
Checks (header-only, no pixel decode):
- 4-byte magic is 'BLP1' or 'BLP2'
- Width/height non-zero and within 8192 (texture exporter cap)
- mipOffsets[16] / mipSizes[16] tables: each non-zero pair refers
to a byte range within the file; mismatched (off=0 with size!=0
or vice versa) flagged
- Stops at first zero offset (BLP convention for unused slots)
Per-version layout differences (BLP1 has compression+alphaBits as
uint32; BLP2 has compression/alphaDepth/alphaEncoding/hasMips as
uint8) handled inline.
Verified on real BLP (pvp-banner-emblem-1.blp): 8 valid mips,
PASSED. Non-BLP file (manifest.json starting with '{'): correctly
flags 'magic is {' error and exits 1.
Format-validator lineup is now exhaustive across both proprietary
and open formats:
Proprietary: BLP / DBC (via --convert-dbc-json round-trip)
Open binary: WOM / WOB / WOC / WHM / GLB
Open text: JSON DBC / STL / PNG (BLP sidecar)
