Method Details

decode

public void decode(AmigaBitmapImage bitmap,
 SEQMovieTrack track)

Specified by:

decode in class SEQFrame

setBounds

public void setBounds(int x,
 int y,
 int w,
 int h)

getTopBound

public int getTopBound(SEQMovieTrack track)

Overrides:

getTopBound in class SEQFrame

getBottomBound

public int getBottomBound(SEQMovieTrack track)

Overrides:

getBottomBound in class SEQFrame

getLeftBound

public int getLeftBound(SEQMovieTrack track)

Overrides:

getLeftBound in class SEQFrame

getRightBound

public int getRightBound(SEQMovieTrack track)

Overrides:

getRightBound in class SEQFrame

isBidirectional

public boolean isBidirectional()

Returns true if the frame can be decoded over both the previous frame or the subsequent frame. Bidirectional frames can be used efficiently for forward and backward playing a movie.

All key frames are bidirectional. Delta frames which use an XOR OP-mode are bidirectional as well.

Overrides:
