RenderedImage (Java Platform SE 7 )

All Known Subinterfaces:

WritableRenderedImage

All Known Implementing Classes:

BufferedImage
```
public interface RenderedImage
```
RenderedImage is a common interface for objects which contain or can produce image data in the form of Rasters. The image data may be stored/produced as a single tile or a regular array of tiles.

- Method Detail
  - getSources
```
Vector<RenderedImage> getSources()
```
    Returns a vector of RenderedImages that are the immediate sources of image data for this RenderedImage. This method returns null if the RenderedImage object has no information about its immediate sources. It returns an empty Vector if the RenderedImage object has no immediate sources.

  - getProperty
```
Object getProperty(String name)

    the ColorModel of this image.
  - getSampleModel
```
SampleModel getSampleModel()

    Returns the width of the RenderedImage.
    
    Returns:
    the width of this RenderedImage.
  - getHeight
```
int getHeight()
```

    the height of this RenderedImage.
  - getMinX
```
int getMinX()

    the X coordinate of this RenderedImage.
  - getMinY
```
int getMinY()
```
    Returns the minimum Y coordinate (inclusive) of the RenderedImage.

    the Y coordinate of this RenderedImage.
  - getNumXTiles
```
int getNumXTiles()
```

    Returns:
    the number of tiles in the X direction.
  - getNumYTiles
```
int getNumYTiles()
```
    Returns the number of tiles in the Y direction.

    Returns the minimum tile index in the X direction.
    
    Returns:
    the minimum tile index in the X direction.
  - getMinTileY

  - getTileHeight
```
int getTileHeight()
```
    Returns the tile height in pixels. All tiles must have the same height.

    the tile height in pixels.
  - getTileGridXOffset
```
int getTileGridXOffset()
```
    Returns the X offset of the tile grid relative to the origin, i.e., the X coordinate of the upper-left pixel of tile (0, 0). (Note that tile (0, 0) may not actually exist.)
    
    Returns:
    the X offset of the tile grid relative to the origin.
  - getTileGridYOffset
```
int getTileGridYOffset()
```
    Returns the Y offset of the tile grid relative to the origin, i.e., the Y coordinate of the upper-left pixel of tile (0, 0). (Note that tile (0, 0) may not actually exist.)
    
    Returns:
    the Y offset of the tile grid relative to the origin.
  - getTile
```
Raster getTile(int tileX,
             int tileY)
```
    Returns tile (tileX, tileY). Note that tileX and tileY are indices into the tile array, not pixel locations. The Raster that is returned is live and will be updated if the image is changed.
    
    Parameters:
    tileX - the X index of the requested tile in the tile array
    tileY - the Y index of the requested tile in the tile array
    
    Returns:
    the tile given the specified indices.
  - getData
```
Raster getData()
```
    Returns the image as one large tile (for tile based images this will require fetching the whole image and copying the image data over). The Raster returned is a copy of the image data and will not be updated if the image is changed.
    
    Returns:
    the image as one large tile.
  - getData
```
Raster getData(Rectangle rect)
```
    Computes and returns an arbitrary region of the RenderedImage. The Raster returned is a copy of the image data and will not be updated if the image is changed.
    
    Parameters:
    rect - the region of the RenderedImage to be returned.
    
    Returns:
    the region of the RenderedImage indicated by the specified Rectangle.
  - copyData
```
WritableRaster copyData(WritableRaster raster)
```
    Computes an arbitrary rectangular region of the RenderedImage and copies it into a caller-supplied WritableRaster. The region to be computed is determined from the bounds of the supplied WritableRaster. The supplied WritableRaster must have a SampleModel that is compatible with this image. If raster is null, an appropriate WritableRaster is created.
    
    Parameters:
    raster - a WritableRaster to hold the returned portion of the image, or null.
    
    Returns:
    a reference to the supplied or created WritableRaster.
