	Name	Description
	anGainExp	The base 2 exponent of the analysis gain of the subband. The analysis gain of a subband is defined as the gain of the previous subband (i.e. the one from which this one was obtained) multiplied by the line gain and by the column gain. The line (column) gain is the gain of the line (column) filter that was used to obtain it, which is the DC gain for a low-pass filter and the Nyquist gain for a high-pass filter. It is 0 by default. Using the base 2 exponent of the value contrains the possible gains to powers of 2. However this is perfectly compatible to the filter normalization policy assumed here. See the split() method for more details. (Inherited from CSJ2K.j2k.wavelet.Subband)
	h	The height of the subband (Inherited from CSJ2K.j2k.wavelet.Subband)
	hFilter	The horizontal analysis filter used to recompose this subband, from its childs. This is applicable to "node" elements only. The default value is null.
	isNode	True if it is a node in the tree, false if it is a leaf. (Inherited from CSJ2K.j2k.wavelet.Subband)
	level	The level in the tree to which this subband belongs, which is the number of performed wavelet decompositions to get this subband. It is 0 for the top-level (i.e. root) node. (Inherited from CSJ2K.j2k.wavelet.Subband)
	magbits	The number of magnitude bits
	nomCBlkH	The nominal code-block height (Inherited from CSJ2K.j2k.wavelet.Subband)
	nomCBlkW	The nominal code-block width (Inherited from CSJ2K.j2k.wavelet.Subband)
	numCb	The number of code-blocks (in both directions) contained in this subband. (Inherited from CSJ2K.j2k.wavelet.Subband)
	orientation	The orientation of this subband (WT_ORIENT_LL, WT_ORIENT_HL, WT_ORIENT_LH, WT_ORIENT_HH). (Inherited from CSJ2K.j2k.wavelet.Subband)
	resLvl	The resolution level to which this subband contributes. 0 is the smallest resolution level (the one with the lowest frequency LL subband). (Inherited from CSJ2K.j2k.wavelet.Subband)
	sbandIdx	The subband index within its resolution level. This value uniquely identifies a subband within a resolution level and a decomposition level within it. Note that only leaf elements represent "real" subbands, while node elements represent only intermediate stages. It is defined recursively. The root node gets a value of 0. For a given node, with a subband index 'b', its LL descendant gets 4b, its HL descendant 4b+1, its LH descendant 4b+2, and its HH descendant 4b+3, for their subband indexes. (Inherited from CSJ2K.j2k.wavelet.Subband)
	ulcx	The horizontal coordinate of the upper-left corner of the subband, with respect to the canvas origin, in the component's grid and subband's decomposition level. This is the real horizontal index of the first column of this subband. If even the horizontal decomposition of this subband should be done with the low-pass-first convention. If odd it should be done with the high-pass-first convention. (Inherited from CSJ2K.j2k.wavelet.Subband)
	ulcy	The vertical coordinate of the upper-left corner of the subband, with respect to the canvas origin, in the component's grid and subband's decomposition level. This is the real vertical index of the first column of this subband. If even the vertical decomposition of this subband should be done with the low-pass-first convention. If odd it should be done with the high-pass-first convention. (Inherited from CSJ2K.j2k.wavelet.Subband)
	ulx	The horizontal coordinate of the upper-left corner of the subband (Inherited from CSJ2K.j2k.wavelet.Subband)
	uly	The vertical coordinate of the upper-left corner of the subband (Inherited from CSJ2K.j2k.wavelet.Subband)
	vFilter	The vertical analysis filter used to decompose this subband, from its childs. This is applicable to "node" elements only. The default value is null.
	w	The width of the subband (Inherited from CSJ2K.j2k.wavelet.Subband)

	Name	Description
	HH	Overridden. Returns the HH child subband of this subband.
	HL	Overridden. Returns the HL (horizontal high-pass) child subband of this subband.
	HorWFilter	Overridden. This function returns the horizontal wavelet filter relevant to this subband
	LH	Overridden. Returns the LH (vertical high-pass) child subband of this subband.
	LL	Overridden. Returns the LL child subband of this subband.
	NextResLevel	Returns the first leaf subband element in the next higher resolution level. (Inherited from CSJ2K.j2k.wavelet.Subband)
	Parent	Overridden. Returns the parent of this subband. The parent of a subband is the subband from which this one was obtained by decomposition. The root element has no parent subband (null).
	VerWFilter	Overridden. This function returns the vertical wavelet filter relevant to this subband

	Name	Description
	getSubband	Returns a reference to the Subband element to which the specified point belongs. The specified point must be inside this (i.e. the one defined by this object) subband. This method searches through the tree. (Inherited from CSJ2K.j2k.wavelet.Subband)
	getSubbandByIdx	Returns a subband element in the tree, given its resolution level and subband index. This method searches through the tree. (Inherited from CSJ2K.j2k.wavelet.Subband)
	nextSubband	Returns the next subband in the same resolution level, following the subband index order. If already at the last subband then null is returned. If this subband is not a leaf an IllegalArgumentException is thrown. (Inherited from CSJ2K.j2k.wavelet.Subband)
	ToString	Returns subband informations in a string. (Inherited from CSJ2K.j2k.wavelet.Subband)
