Constructors

public ConvolveOp (Kernel kernel)

Constructs a ConvolveOp given a Kernel.

Constructs a ConvolveOp given a Kernel. The edge condition
will be EDGE_ZERO_FILL.
Parameters:
- kernel - the specified Kernel
See Also: Kernel, ConvolveOp.EDGE_ZERO_FILL,

public ConvolveOp (Kernel kernel, int edgeCondition, RenderingHints hints)

Constructs a ConvolveOp given a Kernel, an edge condition, and a RenderingHints object (which may be null).

Constructs a ConvolveOp given a Kernel, an edge condition, and a
RenderingHints object (which may be null).
Parameters:
- kernel - the specified Kernel
- edgeCondition - the specified edge condition
- hints - the specified RenderingHints object

Methods

Hide/Show inherited methods

public BufferedImage createCompatibleDestImage (BufferedImage src, ColorModel destCM) [Specified in BufferedImageOp]

Creates a zeroed destination image with the correct size and number of bands.

Creates a zeroed destination image with the correct size and number
of bands. If destCM is null, an appropriate ColorModel will be used.
Returns: a destination BufferedImage with the correct size and number of bands.
Parameters:
- src - Source image for the filter operation.
- destCM - ColorModel of the destination. Can be null.

public WritableRaster createCompatibleDestRaster (Raster src) [Specified in RasterOp]

Creates a zeroed destination Raster with the correct size and number of bands, given this source.

publicfinal BufferedImage filter (BufferedImage src, BufferedImage dst) [Specified in BufferedImageOp]

Performs a convolution on BufferedImages.

Performs a convolution on BufferedImages. Each component of the
source image will be convolved (including the alpha component, if
present).
If the color model in the source image is not the same as that
in the destination image, the pixels will be converted
in the destination. If the destination image is null,
a BufferedImage will be created with the source ColorModel.
The IllegalArgumentException may be thrown if the source is the
same as the destination.
Returns: the filtered BufferedImage
Parameters:
- src - the source BufferedImage to filter
- dst - the destination BufferedImage for the filtered src
Throws:
- NullPointerException - if src is null
- IllegalArgumentException - if src equals dst
- ImagingOpException - if src cannot be filtered

publicfinal WritableRaster filter (Raster src, WritableRaster dst) [Specified in RasterOp]

Performs a convolution on Rasters.

Performs a convolution on Rasters. Each band of the source Raster
will be convolved.
The source and destination must have the same number of bands.
If the destination Raster is null, a new Raster will be created.
The IllegalArgumentException may be thrown if the source is
the same as the destination.
Returns: the filtered WritableRaster
Parameters:
- src - the source Raster to filter
- dst - the destination WritableRaster for the filtered src
Throws:
- NullPointerException - if src is null
- ImagingOpException - if src and dst do not have the same number of bands
- ImagingOpException - if src cannot be filtered
- IllegalArgumentException - if src equals dst

publicfinal Rectangle2D getBounds2D (BufferedImage src) [Specified in BufferedImageOp]

Returns the bounding box of the filtered destination image.

publicfinal Rectangle2D getBounds2D (Raster src) [Specified in RasterOp]

Returns the bounding box of the filtered destination Raster.

public int getEdgeCondition ()

Returns the edge condition.

Returns the edge condition.
Returns: the edge condition of this ConvolveOp.
See Also: ConvolveOp.EDGE_NO_OP, ConvolveOp.EDGE_ZERO_FILL,

publicfinal Kernel getKernel ()

Returns the Kernel.

Returns the Kernel.
Returns: the Kernel of this ConvolveOp.

publicfinal Point2D getPoint2D (Point2D srcPt, Point2D dstPt) [Specified in BufferedImageOp]

Returns the location of the destination point given a point in the source.

publicfinal RenderingHints getRenderingHints () [Specified in BufferedImageOp]

Returns the rendering hints for this op.
