◆ read_iff()

bool LwoSurfaceBlockOpacity::read_iff	(	IffInputFile *	in,

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.
