java.lang.Object | +--quicktime.app.spaces.Sequencer | +--quicktime.app.image.DSequenceFromMemory
This class provides a mechanism for decompressing a sequence of images which were previously compressed using the CSequenceToMemory class.
The decompressed sequence is done with a number of default settings: it uses the port given to it by the displayables parent, it uses no matrix and no mask region, it uses ditherCopy as its transfer mode and it does not use an offscreen buffer or image buffer but writes directly to its destination.

Constructor Summary | |
DSequenceFromMemory(CSequenceToMemory sequenceInMemory)
The Movie Toolbox handles the details of decompressing image sequences in QuickTime movies. |
|
DSequenceFromMemory(EncodedImage data,
ImageDescription description)
This will create an DSequence object from a single piece of data and its description. |
|
DSequenceFromMemory(GraphicsImporter importer)
This will create an DSequence object from a single piece of data and its description. |
|
DSequenceFromMemory(ImageSpec spec)
This will create an DSequence object from any object that implements the ImageSpec interface. |
Method Summary | |
void |
addedTo(java.lang.Object interest)
This method is called by the specified object when the instance of the class that implements this interface is added to the object that is the source of the interest. |
Invalidator |
addedToCompositor(SWCompositor c,
TwoDSprite s)
Returns an object that invalidates a sprite. |
int |
drawCurrentFrame(int inFlags)
Your application calls this method to decompress the current frame. |
Region |
getClip()
Returns a region that defines the current clipping region for the object. |
ImageDescription |
getDescription()
This method should return an ImageDescription that describes the image data that the class contains. |
QDRect |
getDisplayBounds()
QTCanvas calls this method when it needs to ask the client for its boundary. |
GraphicsMode |
getGraphicsMode()
This gets the current GraphicsMode for the compositor. |
QDGraphics |
getGWorld()
QTCanvas calls this method to get the destination QDGraphics of its client. |
EncodedImage |
getImage()
This method returns the actual image data of the current frame or null if there is no image data to return. |
java.awt.Dimension |
getInitialSize()
Deprecated. since QTJava 4.0 |
Matrix |
getMatrix()
This will return the client's current display transformations |
QDDimension |
getOriginalSize()
This method returns the original size before the transformations specified in the returned matrix are applied. |
DSequence |
getSequence()
Returns the CSequence object - this may return null if you haven't called created the sequence. |
void |
redraw(Region invalidRgn)
QTCanvas calls this method when the client should redraw itself. |
void |
removedFrom(java.lang.Object interest)
This method is called by the specified object when the instance of the class that implements this interface is removed from the object that is the source of the interest. |
void |
removedFromCompositor(SWCompositor c)
When a dynamic image class is removed from a SWCompositor this method is called to allow the class to cleanup any of the invalidation processes it had established in the addedToCompositor call. |
void |
setClip(Region reg)
Sets a region that will define the clipping region for the object |
void |
setDisplayBounds(QDRect bounds)
QTCanvas calls this method when it needs to tell the client to adjust its location, width and/or height. |
void |
setGraphicsMode(GraphicsMode mode)
This sets the GraphicsMode for the Compositor when it draws its composited contents to its destination QDGraphics (typically the QTCanvas). |
void |
setGWorld(QDGraphics cgp)
QTCanvas calls this method to give the client the QDGraphics object it should use to do its drawing. |
void |
setLocation(int x,
int y)
A convenience method to set the position of a QTDrawable object. |
void |
setMatrix(Matrix matrix)
This will set the client's current Display Matrix |
int |
size()
Return the number of image data objects (frames) that the object contains. |
java.lang.String |
toString()
Return a string representation of this object |
