/**
* This class represents image data which is stored such that each sample
* of a pixel occupies one data element of the DataBuffer. It stores the
* N samples which make up a pixel in N separate data array elements.
* Different bands may be in different banks of the DataBuffer.
* Accessor methods are provided so that image data can be manipulated
* directly. This class can support different kinds of interleaving, e.g.
* band interleaving, scanline interleaving, and pixel interleaving.
* 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. This class can represent image
* data for which each sample is an unsigned integral number which can be
* stored in 8, 16, or 32 bits (using <code>DataBuffer.TYPE_BYTE</code>,
* <code>DataBuffer.TYPE_USHORT</code>, or <code>DataBuffer.TYPE_INT</code>,
* respectively), data for which each sample is a signed integral number
* which can be stored in 16 bits (using <code>DataBuffer.TYPE_SHORT</code>),
* or data for which each sample is a signed float or double quantity
* (using <code>DataBuffer.TYPE_FLOAT</code> or
* <code>DataBuffer.TYPE_DOUBLE</code>, respectively).
* All samples of a given ComponentSampleModel
* are stored with the same precision. All strides and offsets must be
* non-negative. 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},
