waveletTreeDecomposition() private method

Performs the forward wavelet transform on the whole band. It iteratively decomposes the subbands from the top node to the leaves.

band	CSJ2K.j2k.image.DataBlk	The band containing the float data to decompose /// ///
subband	SubbandAn	The structure containing the coordinates of the current /// subband in the whole band to decompose. /// ///
c	int	The index of the current component to decompose /// ///
return	void

            //not decomposed).
