| UntiledOpImage | | abstract public class UntiledOpImage extends OpImage (Code) | | A general class for single-source operations which require cobbled
sources and create an image consisting of a single tile equal in location
and size to the image bounds.
The output image will have a single tile, regardless of the
ImageLayout settings passed to the constructor. Any
specified settings for tile grid offset and tile dimensions will be
replaced by the image origin and tile dimensions, respectively.
Subclasses should implement the computeImage method
which requests computation of the entire image at once.

| Method Summary | |
| abstract protected void | computeImage(Raster[] sources, WritableRaster dest, Rectangle destRect)
Calculate the destination image from the source image. | | public Raster | computeTile(int tileX, int tileY)
Computes a tile. | | public Point[] | getTileDependencies(int tileX, int tileY, int sourceIndex)
Returns an array of points indicating the tile dependencies which in
this case is the set of all tiles in the specified source image. | | public Rectangle | mapDestRect(Rectangle destRect, int sourceIndex)
Returns the bounds of the indicated source image.
Parameters:
destRect - the Rectangle in destination coordinates (ignored).
Parameters:
sourceIndex - the index of the source image. | | public Rectangle | mapSourceRect(Rectangle sourceRect, int sourceIndex)
Returns the image bounds.
Parameters:
sourceRect - the Rectangle in source coordinates(ignored).
Parameters:
sourceIndex - the index of the source image (ignored). |
| UntiledOpImage | | public UntiledOpImage(Vector sources, Map configuration, ImageLayout layout)(Code) | | Constructs an UntiledOpImage. The image origin and
dimensions, SampleModel, and ColorModel
may optionally be specified by an ImageLayout object.
In all cases the tile grid offset will be set to the image origin
and the tile dimensions to the image dimensions. If not specified
in the ImageLayout, the image origin and dimensions
are set to the corresponding attributes of the first source image.
Cobbling will be performed on the source(s) as needed.
Parameters:
sources - The immediate sources of this image.
Parameters:
configuration - Configurable attributes of the image includingconfiguration variables indexed byRenderingHints.Keys and image properties indexedby Strings or CaselessStringKeys.This is simply forwarded to the superclass constructor.
Parameters:
layout - an ImageLayout optionally containingthe SampleModel, andColorModel. The tile grid layoutinformation will be overridden in order to ensure thatthe image has a single tile.
throws:
IllegalArgumentException - if sourcesis null.
throws:
IllegalArgumentException - If sourcesis non-null and any object insources is null.
throws:
IllegalArgumentException - if sources does notcontain at least one element.
throws:
ClassCastException - If the first object in sourcesis not a RenderedImage.

Parameters:
destRect - the Rectangle in destination coordinates (ignored).
Parameters:
sourceIndex - the index of the source image. The bounds of the indicated source image.
throws:
IllegalArgumentException - if sourceIndex isnegative or greater than the index of the last source. |
| mapSourceRect | | public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code) | | Returns the image bounds.
Parameters:
sourceRect - the Rectangle in source coordinates(ignored).
Parameters:
sourceIndex - the index of the source image (ignored). The image bounds. |
