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.<P><DL><DT><B>See Also: </B><DD><A HREF="../../../java/awt/image/AffineTransformOp.html"><CODE>AffineTransformOp</CODE></A>, <A HREF="../../../java/awt/image/BandCombineOp.html"><CODE>BandCombineOp</CODE></A>, <A HREF="../../../java/awt/image/ColorConvertOp.html"><CODE>ColorConvertOp</CODE></A>, <A HREF="../../../java/awt/image/ConvolveOp.html"><CODE>ConvolveOp</CODE></A>, <A HREF="../../../java/awt/image/LookupOp.html"><CODE>LookupOp</CODE></A>, <A HREF="../../../java/awt/image/RescaleOp.html"><CODE>RescaleOp</CODE></A></DL><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><!-- ======== CONSTRUCTOR SUMMARY ======== --><!-- ========== METHOD SUMMARY =========== --><A NAME="method_summary"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Method Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/awt/image/WritableRaster.html">WritableRaster</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/awt/image/RasterOp.html#createCompatibleDestRaster(java.awt.image.Raster)">createCompatibleDestRaster</A></B>(<A HREF="../../../java/awt/image/Raster.html">Raster</A> src)</CODE><BR> Creates a zeroed destination Raster with the correct size and number of bands.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/awt/image/WritableRaster.html">WritableRaster</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/awt/image/RasterOp.html#filter(java.awt.image.Raster, java.awt.image.WritableRaster)">filter</A></B>(<A HREF="../../../java/awt/image/Raster.html">Raster</A> src, <A HREF="../../../java/awt/image/WritableRaster.html">WritableRaster</A> dest)</CODE><BR> Performs a single-input/single-output operation from a source Raster to a destination Raster.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/awt/geom/Rectangle2D.html">Rectangle2D</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/awt/image/RasterOp.html#getBounds2D(java.awt.image.Raster)">getBounds2D</A></B>(<A HREF="../../../java/awt/image/Raster.html">Raster</A> src)</CODE><BR> Returns the bounding box of the filtered destination Raster.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/awt/geom/Point2D.html">Point2D</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/awt/image/RasterOp.html#getPoint2D(java.awt.geom.Point2D, java.awt.geom.Point2D)">getPoint2D</A></B>(<A HREF="../../../java/awt/geom/Point2D.html">Point2D</A> srcPt, <A HREF="../../../java/awt/geom/Point2D.html">Point2D</A> dstPt)</CODE><BR> Returns the location of the destination point given a point in the source Raster.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE> <A HREF="../../../java/awt/RenderingHints.html">RenderingHints</A></CODE></FONT></TD><TD><CODE><B><A HREF="../../../java/awt/image/RasterOp.html#getRenderingHints()">getRenderingHints</A></B>()</CODE><BR> Returns the rendering hints for this RasterOp.</TD></TR></TABLE> <P><!-- ============ FIELD DETAIL =========== --><!-- ========= CONSTRUCTOR DETAIL ======== --><!-- ============ METHOD DETAIL ========== --><A NAME="method_detail"><!-- --></A><TABLE BORDER="1" CELLPADDING="3" CELLSPACING="0" WIDTH="100%"><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=1><FONT SIZE="+2"><B>Method Detail</B></FONT></TD></TR></TABLE><A NAME="filter(java.awt.image.Raster, java.awt.image.WritableRaster)"><!-- --></A><H3>filter</H3><PRE>public <A HREF="../../../java/awt/image/WritableRaster.html">WritableRaster</A> <B>filter</B>(<A HREF="../../../java/awt/image/Raster.html">Raster</A> src, <A HREF="../../../java/awt/image/WritableRaster.html">WritableRaster</A> dest)</PRE><DL><DD>Performs a single-input/single-output operation from a source Raster to a destination Raster.
