- class java.awt.image..Raster 
public class Raster extends Object 
Tree:java.lang.Object - java.awt.image.Raster
A class representing a rectangular array of pixels. A Raster encapsulates a DataBuffer that stores the sample values and a SampleModel that describes how to locate a given sample value in a DataBuffer.
- Constructor for class java.awt.image.Raster 
protected Raster (SampleModel  sampleModel, DataBuffer  dataBuffer, Point  origin)
Constructs a Raster with the given SampleModel and DataBuffer. The Raster's upper left corner is origin and it is the same size as the SampleModel. The DataBuffer is not initialized and must be compatible with SampleModel.Parameters: sampleModel - The SampleModel that specifies the layout. - The DataBuffer that contains the image data.dataBuffer - The DataBuffer that contains the image data. - The Point that specifies the origin.origin - The Point that specifies the origin.
- Constructor for class java.awt.image.Raster 
protected Raster (SampleModel  sampleModel, DataBuffer  dataBuffer, Rectangle  aRegion, Point  sampleModelTranslate, Raster  parent)
Constructs a Raster with the given SampleModel, DataBuffer, and parent. aRegion specifies the bounding rectangle of the new Raster. When translated into the base Raster's coordinate system, aRegion must be contained by the base Raster. (The base Raster is the Raster's ancestor which has no parent.) sampleModelTranslate specifies the sampleModelTranslateX and sampleModelTranslateY values of the new Raster. Note that this constructor should generally be called by other constructors or create methods, it should not be used directly.Parameters: sampleModel - The SampleModel that specifies the layout. - The DataBuffer that contains the image data.dataBuffer - The DataBuffer that contains the image data. - The Rectangle that specifies the image area.aRegion - The Rectangle that specifies the image area. - The Point that specifies the translation from SampleModel to Raster coordinates.sampleModelTranslate - The Point that specifies the translation from SampleModel to Raster coordinates. - The parent (if any) of this raster.parent - The parent (if any) of this raster.
- Constructor for class java.awt.image.Raster 
protected Raster (SampleModel  sampleModel, Point  origin)
Constructs a Raster with the given SampleModel. The Raster's upper left corner is origin and it is the same size as the SampleModel. A DataBuffer large enough to describe the Raster is automatically created.Parameters: sampleModel - The SampleModel that specifies the layout. - The Point that specified the origin.origin - The Point that specified the origin.
Noman's Java(TM) Glossary
A line of pixels.
Internet Glossary
The rectangular area of a display screen actually being used to display images. The raster is slightly smaller than the physical dimensions of the display screen. Also, the raster varies for different resolutions. For example, VGA resolution of 640x480 on a 15-inch monitor produces one raster, whereas SVGA resolution of 1,024x768 produces a slightly different raster. Most monitors are autosizing, meaning that they automatically use the optimal raster depending on the monitor's size and the video adapter's resolution. In addition, most monitors have controls that allow you move the raster, resize it, and even to rotate it.

Digital Video (DV) & video edit terms / Eng2Eng v1.0 (web compilation)
The scanned area comprising the active portion of a video signal displayed on a cathode ray tube (CRT).
Television and Video Glossary
The illuminated rectangle on the face of a picture tube produced by the scan lines whether showing a picture, a solid color, or snow. "Underscan is when the raster does not fill the screen."
