Detailed Description

The first chunk in a Lightwave Object file.

Definition at line 24 of file lwoHeader.h.

Member Function Documentation

◆ get_version()

double LwoHeader::get_version ( ) const
inline

Returns the version of the Lightwave file.

Definition at line 27 of file lwoHeader.I.

◆ is_valid()

bool LwoHeader::is_valid ( ) const
inline

Returns true if the header represents a valid and recognized Lightwave header, false otherwise.

Definition at line 19 of file lwoHeader.I.

◆ read_iff()

bool LwoHeader::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.
