| PointOpImage | | abstract public class PointOpImage extends OpImage (Code) | | An abstract base class for image operators that require only the
(x, y) pixel from each source image in order to compute the
destination pixel (x, y).
PointOpImage is intended as a convenient
superclass for OpImages that only need to look at each
destination pixel's corresponding source pixels. Some examples are
lookup, contrast adjustment, pixel arithmetic, and color space
conversion.

| public | PointOpImage(Vector sources, ImageLayout layout, Map configuration, boolean cobbleSources)
Constructor.
There must be at least one valid source supplied via the
sources argument. | | public | PointOpImage(RenderedImage source, ImageLayout layout, Map configuration, boolean cobbleSources)
Constructs a PointOpImage with one source image. | | public | PointOpImage(RenderedImage source0, RenderedImage source1, ImageLayout layout, Map configuration, boolean cobbleSources)
Constructs a PointOpImage with two source images. | | public | PointOpImage(RenderedImage source0, RenderedImage source1, RenderedImage source2, ImageLayout layout, Map configuration, boolean cobbleSources)

| Method Summary | |
| public Raster | computeTile(int tileX, int tileY)
Computes a tile. | | public synchronized void | dispose()
Disposes of any remaining tiles in the TileCache. | | protected boolean | isColormapOperation()
Indicates whether the operation is being effected directly on the
associated colormap. | | final public Rectangle | mapDestRect(Rectangle destRect, int sourceIndex)
Returns a conservative estimate of the region of a specific
source that is required in order to compute the pixels of a
given destination rectangle. | | final public Rectangle | mapSourceRect(Rectangle sourceRect, int sourceIndex)
Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source. | | protected void | permitInPlaceOperation()
Causes a flag to be set to indicate that in-place operation should
be permitted if the image bounds, tile grid offset, tile dimensions,
and SampleModels of the source and destination images are compatible.
This method should be invoked in the constructor of the implementation
of a given operation only if that implementation is amenable to
in-place computation. |
| PointOpImage | | public PointOpImage(Vector sources, ImageLayout layout, Map configuration, boolean cobbleSources)(Code) | | Constructor.
There must be at least one valid source supplied via the
sources argument. However, there is no upper limit
on the number of sources this image may have.
The image's layout is encapsulated in the layout
argument. If the image bounds are supplied they must be contained
within the intersected source bounds which must be non-empty.
If the bounds are not supplied, they are calculated to be the
intersection of the bounds of all sources.
If no SampleModel is specified in the layout, a new
SampleModel will be created. This SampleModel
will have a number of bands equal to the minimum band count of all
sources and a depth which can accomodate the data of all sources.
The band count of sources which have an IndexColorModel
will be set to the number of components of the
IndexColorModel instead of to the number of bands of the
SampleModel.
In all cases, the layout is forwarded to the OpImage
constructor which sets the default layout values in the standard way.
Parameters:
layout - The layout parameters of the destination image.
Parameters:
sources - The source images.
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:
cobbleSources - true if computeRect() expectscontiguous sources.
throws:
IllegalArgumentException - If sources or anyobject in sources is null.
throws:
IllegalArgumentException - if sources does notcontain at least one element.
throws:
ClassCastException - If any object in sourcesis not a RenderedImage.
throws:
IllegalArgumentException - If combining the intersectedsource bounds with the user-specified bounds, if any,yields an empty rectangle, or the user-specified image boundsextends beyond the intersection of all the source bounds.

| computeTile | | public Raster computeTile(int tileX, int tileY)(Code) | | Computes a tile. If source cobbling was requested at
construction time, the source tile boundaries are overlayed
onto the destination and computeRect(Raster[],
WritableRaster, Rectangle) is called for each of the
resulting regions. Otherwise, computeRect(PlanarImage[],
WritableRaster, Rectangle) is called once to compute the
entire active area of the tile.
The image bounds may be larger than the bounds of the
source image. In this case, samples for which there are no
corresponding sources are set to zero.
Parameters:
tileX - The X index of the tile.
Parameters:
tileY - The Y index of the tile. |
| dispose | | public synchronized void dispose()(Code) | | Disposes of any remaining tiles in the TileCache.
If cache is non-null, in place operation
is enabled, and tileRecycler is non-null,
then all tiles owned by this specific image are removed from the cache.
Subsequent to this super.dispose() is invoked.
since:
JAI 1.1.2 |
| isColormapOperation | | protected boolean isColormapOperation()(Code) | | Indicates whether the operation is being effected directly on the
associated colormap. This method will in general return
true if the image is the destination of a unary,
shift-invariant operation with an IndexColorModel equal
to that of its unique source.
When this method returns true the
computeTile() method in this class will return either
a copy of the corresponding region of the first source image or,
if the operation is being performed in place, the corresponding
tile of the first source image.
The implementation in this class always returns false.
since:
JAI 1.1 |
| mapDestRect | | final public Rectangle mapDestRect(Rectangle destRect, int sourceIndex)(Code) | | Returns a conservative estimate of the region of a specific
source that is required in order to compute the pixels of a
given destination rectangle. The resulting Rectangle
is not clipped to the source image bounds.
Parameters:
destRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the potentially affecteddestination region.
throws:
IllegalArgumentException - if sourceIndex isnegative or greater than the index of the last source.
throws:
IllegalArgumentException - if destRect isnull. |
| mapSourceRect | | final public Rectangle mapSourceRect(Rectangle sourceRect, int sourceIndex)(Code) | | Returns a conservative estimate of the destination region that
can potentially be affected by the pixels of a rectangle of a
given source. The resulting Rectangle is not
clipped to the destination image bounds.
Parameters:
sourceRect - the Rectangle in source coordinates.
Parameters:
sourceIndex - the index of the source image. a Rectangle indicating the potentially affecteddestination region, or null if the region is unknown.
throws:
IllegalArgumentException - if sourceIndex isnegative or greater than the index of the last source.
throws:
IllegalArgumentException - if sourceRect isnull. |
| permitInPlaceOperation | | protected void permitInPlaceOperation()(Code) | | Causes a flag to be set to indicate that in-place operation should
be permitted if the image bounds, tile grid offset, tile dimensions,
and SampleModels of the source and destination images are compatible.
This method should be invoked in the constructor of the implementation
of a given operation only if that implementation is amenable to
in-place computation. Invocation of this method is a necessary but
not a sufficient condition for in-place computation actually to occur.
If the system property "javax.media.jai.PointOpImage.InPlace" is equal
to the string "false" in a case-insensitive fashion then in-place
operation will not be permitted.
