All Implemented Interfaces:

RenderedImage

Direct Known Subclasses:

SingleTileRenderedImage
```
public abstract class SimpleRenderedImage
extends Object
implements RenderedImage
```
A simple class implemented the RenderedImage interface. Only the getTile() method needs to be implemented by subclasses. The instance variables must also be filled in properly.
Normally in JAI PlanarImage is used for this purpose, but in the interest of modularity the use of PlanarImage has been avoided.

  - getSources
```
public Vector getSources()
```
    Specified by:
    
    getSources in interface RenderedImage
  - getData
```
public Raster getData()
```
    Returns the entire image in a single Raster. For images with multiple tiles this will require making a copy.
    The returned Raster is semantically a copy. This means that updates to the source image will not be reflected in the returned Raster. For non-writable (immutable) source images, the returned value may be a reference to the image's internal data. The returned Raster should be considered non-writable; any attempt to alter its pixel data (such as by casting it to WritableRaster or obtaining and modifying its DataBuffer) may result in undefined behavior. The copyData method should be used if the returned Raster is to be modified.
    
    Specified by:
    
    getData in interface RenderedImage
    
    Returns:
    
    a Raster containing a copy of this image's data.
  - getData
```
public Raster getData(Rectangle bounds)
```
    Returns an arbitrary rectangular region of the RenderedImage in a Raster. The rectangle of interest will be clipped against the image bounds.
    The returned Raster is semantically a copy. This means that updates to the source image will not be reflected in the returned Raster. For non-writable (immutable) source images, the returned value may be a reference to the image's internal data. The returned Raster should be considered non-writable; any attempt to alter its pixel data (such as by casting it to WritableRaster or obtaining and modifying its DataBuffer) may result in undefined behavior. The copyData method should be used if the returned Raster is to be modified.
    
    Specified by:
    
    getData in interface RenderedImage
    
    Parameters:
    
    bounds - the region of the RenderedImage to be returned.
  - copyData
```
public WritableRaster copyData(WritableRaster dest)
```
    Copies an arbitrary rectangular region of the RenderedImage into a caller-supplied WritableRaster. The region to be computed is determined by clipping the bounds of the supplied WritableRaster against the bounds of the image. The supplied WritableRaster must have a SampleModel that is compatible with that of the image.
    If the raster argument is null, the entire image will be copied into a newly-created WritableRaster with a SampleModel that is compatible with that of the image.
    
    Specified by:
    
    copyData in interface RenderedImage
    
    Parameters:
    
    dest - a WritableRaster to hold the returned portion of the image.
    
    Returns:
    
    a reference to the supplied WritableRaster, or to a new WritableRaster if the supplied one was null.
