| /** |
| * This abstract class defines an interface for extracting samples of pixels |
| * in an image. All image data is expressed as a collection of pixels. |
| * Each pixel consists of a number of samples. A sample is a datum |
| * for one band of an image and a band consists of all samples of a |
| * particular type in an image. For example, a pixel might contain |
| * three samples representing its red, green and blue components. |
| * There are three bands in the image containing this pixel. One band |
| * consists of all the red samples from all pixels in the |
| * image. The second band consists of all the green samples and |
| * the remaining band consists of all of the blue samples. The pixel |
| * can be stored in various formats. For example, all samples from |
| * a particular band can be stored contiguously or all samples from a |
| * single pixel can be stored contiguously. |
| * <p> |
| * Subclasses of SampleModel specify the types of samples they can |
| * represent (e.g. unsigned 8-bit byte, signed 16-bit short, etc.) |
| * and may specify how the samples are organized in memory. |
| * In the Java 2D(tm) API, built-in image processing operators may |
| * not operate on all possible sample types, but generally will work |
| * for unsigned integral samples of 16 bits or less. Some operators |
| * support a wider variety of sample types. |
| * <p> |
| * A collection of pixels is represented as a Raster, which consists of |
| * a DataBuffer and a SampleModel. The SampleModel allows access to |
| * samples in the DataBuffer and may provide low-level information that |
| * a programmer can use to directly manipulate samples and pixels in the |
| * DataBuffer. |
| * <p> |
| * This class is generally a fall back method for dealing with |
| * images. More efficient code will cast the SampleModel to the |
| * appropriate subclass and extract the information needed to directly |
| * manipulate pixels in the DataBuffer. |
