/**
 *  This class represents image data which is stored in a pixel interleaved
 *  fashion and for
 *  which each sample of a pixel occupies one data element of the DataBuffer.
 *  It subclasses ComponentSampleModel but provides a more efficient
 *  implementation for accessing pixel interleaved image data than is provided
 *  by ComponentSampleModel.  This class
 *  stores sample data for all bands in a single 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. 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.
 *  This class supports
 *  {@link DataBuffer#TYPE_BYTE TYPE_BYTE},
 *  {@link DataBuffer#TYPE_USHORT TYPE_USHORT},
 *  {@link DataBuffer#TYPE_SHORT TYPE_SHORT},
 *  {@link DataBuffer#TYPE_INT TYPE_INT},
 *  {@link DataBuffer#TYPE_FLOAT TYPE_FLOAT} and
 *  {@link DataBuffer#TYPE_DOUBLE TYPE_DOUBLE} datatypes.
