IffChunk * IffChunk::make_new_chunk (  IffInputFile *  in, IffId  id )  [virtual, inherited]

Allocates and returns a new chunk of the appropriate type based on the given ID, according to the context given by this chunk itself. Reimplemented in LwoClip, LwoSurface, LwoSurfaceBlock, LwoSurfaceBlockHeader, and LwoSurfaceBlockTMap. Definition at line 66 of file iffChunk.cxx.

bool LwoSurfaceBlockOpacity::read_iff (  IffInputFile *  in, size_t  stop_at )  [virtual]

Reads the data of the chunk in from the given input file, if possible. The ID and length of the chunk have already been read. stop_at is the byte position of the file to stop at (based on the current position at in->get_bytes_read()). Returns true on success, false otherwise. Implements IffChunk. Definition at line 49 of file lwoSurfaceBlockOpacity.cxx. References _envelope, _opacity, _type, IffChunk::get_id(), and indent().
