java.awt.image
Class ConvolveOp
- BufferedImageOp, RasterOp
Convolution filter.
ConvolveOp convolves the source image with a Kernel to generate a
destination image. This involves multiplying each pixel and its neighbors
with elements in the kernel to compute a new pixel.
Each band in a Raster is convolved and copied to the destination Raster.
For BufferedImages, convolution is applied to all components. If the
source is not premultiplied, the data will be premultiplied before
convolving. Premultiplication will be undone if the destination is not
premultiplied. Color conversion will be applied if needed.

EDGE_NO_OP
public static final int EDGE_NO_OP
Edge pixels are copied from the source.
EDGE_ZERO_FILL
public static final int EDGE_ZERO_FILL
Edge pixels are set to 0.
ConvolveOp
public ConvolveOp(Kernel kernel)
Construct a ConvolveOp.
The edge condition defaults to EDGE_ZERO_FILL.
kernel
- The kernel to convolve with.
ConvolveOp
public ConvolveOp(Kernel kernel,
int edgeCondition,
RenderingHints hints)
Construct a ConvolveOp.
The edge condition specifies that pixels outside the area that can be
filtered are either set to 0 or copied from the source image.
kernel
- The kernel to convolve with.edgeCondition
- Either EDGE_ZERO_FILL or EDGE_NO_OP.hints
- Rendering hints for color conversion, or null.
getKernel
public Kernel getKernel()
Returns (a clone of) the convolution kernel.
