/** |

* This class defines a Raster with pixels consisting of one or more 16-bit |
|
40 |
* data elements stored in close proximity to each other in a short integer |
|
41 |
* array. The bit precision per data element is that |
|
42 |
* of the data type (that is, the bit precision for this Raster is 16). |
|
43 |
* There is only one pixel stride and one scanline stride for all |
|
44 |
* bands. This type of Raster can be used with a |
|
45 |
* ComponentColorModel if there are multiple bands, or a |
|
46 |
* IndexColorModel if there is only one band. |
|
47 |
* <p> |
|
48 |
* For example, 5-6-5 RGB image data can be represented by a |
|
49 |
* ShortComponentRaster using a SinglePixelPackedSampleModel and |
|
50 |
* a ComponentColorModel. |
