imageBlocks

private int[][][][][][][] imageBlocks

This multidimensional array of ints contains the image divided into blocks. The indices are imageBlocks[z][resolutionLevel][subband][yBlock][xBlock] in the next manner:
zIndex: is a index on the image components
resolutionLevel: 0 is the LL subband, and 1, 2, ... represents next starting with the little one
subband: 0 - HL, 1 - LH, 2 - HH (if resolutionLevel == 0 --> 0 - LL)
yBlock: block row in the subband
xBlock: block column in the subband
y: sample row
x: sample column

Content is the image pixel coefficients.

resolutionLevelAchieved

private int resolutionLevelAchieved

Is the suitable resolution level to be decoded.

precinctWidths

private int[][] precinctWidths

Definition in CODParameters.precinctWidths

precinctHeights

private int[][] precinctHeights

Definition in CODParameters.precinctHeights
