     mvMatrix:	mvSetMovieMatrix2dIdentity, mvSetMovieMatrix2d,
     mvGetMovieMatrix2d, mvSetTrackMatrix2dIdentity, mvSetTrackMatrix2d,
     mvGetTrackMatrix2d	- Matrix manipulation of movie and track

SYNOPSIS    [Toc]    [Back]

     #include <dmedia/moviefile.h>

     DMstatus mvSetMovieMatrix2dIdentity( MVid movie );

     DMstatus mvSetMovieMatrix2d( MVid movie, MVmatrix2d matrix	);

     DMstatus mvGetMovieMatrix2d( MVid movie, MVmatrix2d matrix	);

     DMstatus mvSetTrackMatrix2dIdentity( MVid track );

     DMstatus mvSetTrackMatrix2d( MVid track, MVmatrix2d matrix	);

     DMstatus mvGetTrackMatrix2d( MVid track, MVmatrix2d matrix	);

DESCRIPTION    [Toc]    [Back]

     This set of functions manipulate the 2-dimension matrix associated	with
     each movie	and track.  MVmatrix2d is a 3 by 3 2-dimensional array.

     These matrices affects how	visual tracks are laid out with	respect	to
     each other.  It also affects how the movie	is laid	out on the screen.
     These matrices have no effects on aural tracks.

     mvSetMovieMatrix2d	sets the movie matrix of movie to matrix.

     mvSetMovieMatrix2dIdentity	is a convenience function that sets the	movie
     matrix of movie to	an identity matrix.

     mvGetMovieMatrix2d	returns	the movie matrix of movie in matrix.

     mvSetTrackMatrix2d	sets the track matrix of track to matrix.

     mvSetTrackMatrix2dIdentity	is a convenience function that sets the	track
     matrix of track to	an identity matrix.

     mvGetTrackMatrix2d	returns	the track matrix of track to matrix.

NOTES    [Toc]    [Back]

     Currently,	only translation and scaling factors are supported.
     Rotational	factors	in the matrix are ignored in the display of the	image,
     although they are preserved in the	file if	set.
