It subclasses ComponentSampleModel but provides a more efficent implementation for accessing band interleaved image data than is provided by ComponentSampleModel. This class should typically be used when working with images which store sample data for each band in a different bank of the DataBuffer. Accessor methods are provided so that image data can be manipulated directly. Pixel stride is the number of data array elements between two samples for the same band on the same scanline. The pixel stride for a BandedSampleModel is one. Scanline stride is the number of data array elements between a given sample and the corresponding sample in the same column of the next scanline. Band offsets denote the number of data array elements from the first data array element of the bank of the DataBuffer holding each band to the first sample of the band. The bands are numbered from 0 to N-1. Bank indices denote the correspondence between a bank of the data buffer and a band of image data.
