prepare()

template<typename Chunk>

void wowlib::formats::adt::detail::AlphaCodec::prepare ( const Chunk & self, AlphaFormat af, std::vector< std::byte > & blob, std::vector< SMLayer > & stamped )

Build the MCAL blob and the layers copy carrying each layer's derived offsetInMcal (MCLY emits that copy).

Called once before the write walk.

Parameters

self	the chunk.
af	the tile alpha bit depth.
blob	receives the encoded MCAL bytes.
stamped	receives the layers with offsetInMcal stamped.
