| SourcelessOpImage | | abstract public class SourcelessOpImage extends OpImage (Code) | | An abstract base class for image operators that have no image
sources.
SourcelessOpImage is intended as a convenient superclass
for OpImages that have no source image. Some examples are
constant color images, file readers, protocol-based network readers,
and mathematically-defined imagery such as fractals.
The computeTile method of this class will call the
computeRect(PlanarImage[], WritableRaster, Rectangle)
method of the subclass to perform the computation. The first
argument will be null as there are no source images.

| Constructor Summary | |
| public | SourcelessOpImage(ImageLayout layout, Map configuration, SampleModel sampleModel, int minX, int minY, int width, int height)
Constructs a SourcelessOpImage. |
| Method Summary | |
| public Raster | computeTile(int tileX, int tileY)
Computes a tile. | | public boolean | computesUniqueTiles()
Returns false as SourcelessOpImages often return Rasters
via computeTile() tile that are internally cached. | | public Rectangle | mapDestRect(Rectangle destRect, int sourceIndex)
Throws an IllegalArgumentException since the image has no image
sources. | | public Rectangle | mapSourceRect(Rectangle sourceRect, int sourceIndex)
Throws an IllegalArgumentException since the image has no image
sources. |
| SourcelessOpImage | | public SourcelessOpImage(ImageLayout layout, Map configuration, SampleModel sampleModel, int minX, int minY, int width, int height)(Code) | | Constructs a SourcelessOpImage. The image bounds
and SampleModel are set explicitly; other layout
parameters may be set using the layout parameter.
The min X, min Y, width, height, and SampleModel
fields of the layout parameter are ignored.
If sampleModel is null, no
exceptions will be thrown. However, the caller must be sure to
set the sampleModel instance variable before
construction terminates. This feature allows subclasses that
require external computation such as file loading to defer the
determination of their SampleModel until after the
call to super.
Similarly, minX, minY,
width, and height may be dummy values
if care is taken to manually set all values that depend on
them, namely the tile grid offset, tile size, and
SampleModel width and height.
The tile dimensions, tile grid X and Y offsets, and
ColorModel of the output will be set in the standard
way by the OpImage constructor.
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 describing the layout.

| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | Computes a tile. Since the operation has no sources,
there is no need to worry about cobbling.
Subclasses should implement the
computeRect(PlanarImage[], WritableRaster, Rectangle)
method to perform the actual computation.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. |
| computesUniqueTiles | | public boolean computesUniqueTiles()(Code) | | Returns false as SourcelessOpImages often return Rasters
via computeTile() tile that are internally cached. Some
subclasses may want to override this method and return true.
|
| mapDestRect | | public Rectangle mapDestRect(Rectangle destRect, int sourceIndex)(Code) | | Throws an IllegalArgumentException since the image has no image
sources.
Parameters:
destRect - ignored.
Parameters:
sourceIndex - ignored.
throws:
IllegalArgumentException - since the image has no sources. |
| mapSourceRect | | public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code) | | Throws an IllegalArgumentException since the image has no image
sources.
Parameters:
sourceRect - ignored.
Parameters:
sourceIndex - ignored.
throws:
IllegalArgumentException - since the image has no sources. |
