Constructor Detail

ANIMFrame

public ANIMFrame()

Method Detail

addAudioCommand

public void addAudioCommand(ANIMAudioCommand command)

Adds an audio command to this anim frame.

getAudioCommands

public ANIMAudioCommand[] getAudioCommands()

Returns audio commands associated with this frame. Returns null if there are no audio commands available for this frame.

cleanUpAudioCommands

public void cleanUpAudioCommands()

Removes duplicate audio commands.

setColorModel

public void setColorModel(java.awt.image.ColorModel cm)

getColorModel

public java.awt.image.ColorModel getColorModel()

setData

public void setData(byte[] data)

setOperation

public void setOperation(int operation)

setMask

public void setMask(int mask)

setWidth

public void setWidth(int w)

setHeight

public void setHeight(int h)

setX

public void setX(int x)

setY

public void setY(int y)

setAbsTime

public void setAbsTime(long abstime)

setRelTime

public void setRelTime(long reltime)

setInterleave

public void setInterleave(int interleave)

setBits

public void setBits(int bits)

getOperation

public int getOperation()

getBits

public int getBits()

getRelTime

public long getRelTime()

getInterleave

public int getInterleave()

decode

public abstract void decode(BitmapImage bitmap,
                            ANIMMovieTrack track)

getTopBound

public int getTopBound(ANIMMovieTrack track)

getBottomBound

public int getBottomBound(ANIMMovieTrack track)

getLeftBound

public int getLeftBound(ANIMMovieTrack track)

getRightBound

public int getRightBound(ANIMMovieTrack track)

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.
