public interface RasterOp
This interface describes single-input/single-output
 operations performed on Raster objects.  It is implemented by such
 classes as AffineTransformOp, ConvolveOp, and LookupOp.  The Source
 and Destination objects must contain the appropriate number
 of bands for the particular classes implementing this interface.
 Otherwise, an exception is thrown.  This interface cannot be used to
 describe more sophisticated Ops such as ones that take multiple sources.
 Each class implementing this interface will specify whether or not it
 will allow an in-place filtering operation (i.e. source object equal
 to the destination object).  Note that the restriction to single-input
 operations means that the values of destination pixels prior to the
 operation are not used as input to the filter operation.

Method SummaryModifier and TypeMethodDescriptionCreates a zeroed destination Raster with the correct size and number of bands.filter(Raster src, WritableRaster dest) Performs a single-input/single-output operation from a source Raster to a destination Raster.getBounds2D(Raster src) Returns the bounding box of the filtered destination Raster.getPoint2D(Point2D srcPt, Point2D dstPt) Returns the location of the destination point given a point in the source Raster.Returns the rendering hints for this RasterOp.

Method Details- 
filterPerforms a single-input/single-output operation from a source Raster to a destination Raster. If the destination Raster is null, a new Raster will be created. The IllegalArgumentException may be thrown if the source and/or destination Raster is incompatible with the types of Rasters allowed by the class implementing this filter.- Parameters:
- src- the source- Raster
- dest- the destination- WritableRaster
- Returns:
- a WritableRasterthat represents the result of the filtering operation.
 
- 
getBounds2DReturns the bounding box of the filtered destination Raster. The IllegalArgumentException may be thrown if the source Raster is incompatible with the types of Rasters allowed by the class implementing this filter.- Parameters:
- src- the source- Raster
- Returns:
- a Rectangle2Dthat is the bounding box of theRasterresulting from the filtering operation.
 
- 
createCompatibleDestRasterCreates a zeroed destination Raster with the correct size and number of bands. The IllegalArgumentException may be thrown if the source Raster is incompatible with the types of Rasters allowed by the class implementing this filter.- Parameters:
- src- the source- Raster
- Returns:
- a WritableRasterthat is compatible withsrc
 
- 
getPoint2DReturns the location of the destination point given a point in the source Raster. If dstPt is non-null, it will be used to hold the return value.- Parameters:
- srcPt- the source- Point2D
- dstPt- the destination- Point2D
- Returns:
- the location of the destination point.
 
- 
getRenderingHintsRenderingHints getRenderingHints()Returns the rendering hints for this RasterOp. Returns null if no hints have been set.- Returns:
- the RenderingHintsobject of thisRasterOp.
