-/**
- * ComponentSampleModel supports a flexible organization of pixel samples in
- * memory, permitting pixel samples to be interleaved by band, by scanline,
- * and by pixel.
- *
- * A DataBuffer for this sample model has K banks of data.  Pixels have N
- * samples, so there are N bands in the DataBuffer.  Each band is completely
- * contained in one bank of data, but a bank may contain more than one band.
- * Each pixel sample is stored in a single data element.
- *
- * Within a bank, each band begins at an offset stored in bandOffsets.  The
- * banks containing the band is given by bankIndices.  Within the bank, there
- * are three dimensions - band, pixel, and scanline.  The dimension ordering
- * is controlled by bandOffset, pixelStride, and scanlineStride, which means
- * that any combination of interleavings is supported.
- *
