public class CSequenceToMemory

extends java.lang.Object

This class provides a mechanism for compressing a sequence of images to memory. The compressed images are maintained internally. Use the DSequenceFromMemory class to decompress a sequence of images from a CSequenceToMemory object.

When compressing a sequence of images you want to keep in memory you would use this class and use the compressFrame call that belongs here. This class will then handle the memory that the compressed image is loaded into. If you call one of the super compressFrame calls then this class does NOT know about the compressed data.

Constructor Detail

CSequenceToMemory

public CSequenceToMemory(int numFrames)

Deprecated. since QTJava 6.1

Create an instance of this class in order to compress a sequence of frames and store them in memory. You must call begin before you use any other methods

Parameters:

numFrames - the number of Frames that the compression will hold

Deprecated. since QTJava 6.1

Create an instance of this class in order to compress a sequence of frames and store them in memory.

Parameters:

src - a QDGraphics containing the PixMap object containing the source data to be compressed

srcRect - a QDRect defining the portion of the image to compress

depth - the depth of the color or 0 for the current device's depth

cType - the compressor type

codec - the compressor identifier

spatialQuality - the desired compressed image quality

temporalQuality - the desired sequence temporal quality

keyFrameRate - the maximum number of frames allowed between key frames

cTab - the ColorTable or null that is used in the compression

flags - flags providing further control information

Method Detail

begin

public void begin(QDGraphics src,
                  QDRect srcRect,
                  int colorDepth,
                  int cType,

           throws QTException

Deprecated. since QTJava 6.1

Signals the beginning of the process of compressing a sequence of frames.

Parameters:

src - a QDGraphics containing the PixMap object containing the source data to be compressed

srcRect - a QDRect defining the portion of the image to compress

colorDepth - the depth at which the sequence is likely to be viewed

cType - the compressor type

codec - the compressor identifier

spatialQuality - the desired compressed image quality

temporalQuality - the desired sequence temporal quality

keyFrameRate - the maximum number of frames allowed between key frames

clut - a custum color lookup table

flags - flags providing further control information

QTException

compressFrame

public int compressFrame(QDGraphics src,
                         QDRect srcRect,
                         int flags)
                  throws QTException

Deprecated. since QTJava 6.1

Your application calls this method to compress one of a sequence of frames. The similarity value is directly returned by this method.
Note: See the QTImage class and Inside Mac QuickTime documentation for more information on valid flag values.

Parameters:

src - a QDGraphics containing the PixMap that contains the image to be compressed

srcRect - a QDRect defining the portion of the image to compress

flags - flags providing further control information

Returns:

the similarity value

QTException

getDescription

public ImageDescription getDescription()
                                throws QTException

Deprecated. since QTJava 6.1

This method should return an ImageDescription that describes the image data that the class contains.

Returns:

the ImageDescription of an Image

QTException

getSequence

public CSequence getSequence()

Deprecated. since QTJava 6.1

Returns the CSequence object - this may return null if you haven't called created the sequence.

Returns:

the sequence
