This class represents a vector data stream for QuickTime Vector component. It
holds a stream of Atoms which constructs the vector to be drawn. This class
is used to add the data atoms which are either the paths or the attributes
of the path. A ZeroAtom at the end of the stream marks the end of datastream.
It should be noted that all the addAtom calls which need the data to be Endian flipped
is done internally by the class, unless explicitly mentioned.

VectorStream
public VectorStream(Curve c)
throws QTException
- Used to create an empty vector data stream.
QuickTime::CurveCreateVectorStream
- Parameters:
c
- the curve component
addPathAtom
public void addPathAtom(QTHandle pathData)
throws QTException
- Used to add a path to a vector data stream.
QuickTime::CurveAddPathAtomToVectorStream
- Parameters:
pathData
- Contains a handle to the data for the path.
addZeroAtom
public void addZeroAtom()
throws StdQTException
- Used to add a kCurveEndAtom to a vector data stream. This atom marks the end of the vector data stream.
QuickTime::CurveAddZeroAtomToVectorStream
addAtom
public void addAtom(int atomType,
byte[] atomData)
throws StdQTException
- Used to add an atom to a vector data stream. When using this call make sure that the
byte array passed in has all its bytes flipped to BigEndian .
QuickTime::CurveAddAtomToVectorStream
- Parameters:
atomType
- Specifies the type of atom to add to the vector data stream.atomData
- the data for the atom.The EndianFlipping should be done by the application
addAtom
public void addAtom(QDColor col)
throws QTException
- Used to add kCurveARGBColorAtom atom to a vector data stream.
QuickTime::CurveAddAtomToVectorStream
- Parameters:
col
- Specifies the QDColor to be added.
addAtom
public void addAtom(int atomType,
int atomData)
throws StdQTException
- Used to add an atom to a vector data stream.
QuickTime::CurveAddAtomToVectorStream
- Parameters:
atomType
- Specifies the type of atom to add to the vector data stream.atomData
- the data for the atom.
addAtom
public void addAtom(boolean onCurve,
QDPoint[] points)
throws StdQTException
- Used to add an atom of type kCurvePathAtom to a vector data stream. By default this has one contour per path.
This is used to add points that are all on curve or off curve.

removeAtom
public void removeAtom(int atomType)
throws StdQTException
- Used to remove and atom of given type ex. kCurveGradientRecordAtom can be disabled
by making this call so that all atoms added after this atom do not have
Gradient.
