All known Subclasses: jj2000.j2k.wavelet.synthesis.SynWTFilterIntLift5x3,
| SynWTFilterInt | | abstract public class SynWTFilterInt extends SynWTFilter (Code) | | This extends the synthesis wavelet filter general definitions of
SynWTFilter by adding methods that work for int data
specifically. Implementations that work on int data should inherit
from this class.
See the SynWTFilter class for details such as
normalization, how to split odd-length signals, etc.
The advantage of using the specialized method is that no casts
are performed.

| Method Summary | |
| public int | getDataType()
Returns the type of data on which this filter works, as defined
in the DataBlk interface, which is always TYPE_INT for this
class. | | abstract public void | synthetize_hpf(int[] lowSig, int lowOff, int lowLen, int lowStep, int[] highSig, int highOff, int highLen, int highStep, int[] outSig, int outOff, int outStep)
A specific version of the synthetize_hpf() method that works on int
data. | | public void | synthetize_hpf(Object lowSig, int lowOff, int lowLen, int lowStep, Object highSig, int highOff, int highLen, int highStep, Object outSig, int outOff, int outStep)
The general version of the synthetize_hpf() method, it just calls
the specialized version. | | abstract public void | synthetize_lpf(int[] lowSig, int lowOff, int lowLen, int lowStep, int[] highSig, int highOff, int highLen, int highStep, int[] outSig, int outOff, int outStep)

| getDataType | | public int getDataType()(Code) | | Returns the type of data on which this filter works, as defined
in the DataBlk interface, which is always TYPE_INT for this
class.
