java.lang.Object | +--jj2000.j2k.wavelet.synthesis.InvWTHelper
This abstract class provides default implementations of some of methods that are useful for inverse wavelet transforms. The implementations are general and can suit most inverse DWT implementation.
Field Summary | |
(package private) boolean[][] |
reversible
The reversible flag for each component in each tile. |
(package private) InvWTData |
src
The source of wavelet transform coefficients for the transform for which this object is intended to be the helper. |
Constructor Summary | |
InvWTHelper(InvWTData src)
Instantiates a new 'InvWTHelper' object to work with the specified source of wavelet coefficients. |
Method Summary | |
boolean |
isReversible(int t,
int c)
Returns the reversibility of the wavelet transform for the specified tile-component. |
private boolean |
isSubbandReversible(Subband subband)
Returns the reversibility of the current subband. |
