This // * operation uses a box of {@code size}×{@code size} pixels centered on each {@code NaN} // * value, where {@code size} = 2×{@code padding}+1 (the <cite>padding</cite> is the number // * of pixel above, below, to the left and to the right of central {@code NaN} pixel). The weighted // * average is then computed, ignoring all {@code NaN} values. If the number of valid values is // * greater than or equals to {@code validityThreshold}, then the center {@code NaN} is replaced by // * the computed average. Otherwise, the {@code NaN} value is left unchanged. // * // * <P><STRONG>Name:</STRONG> <CODE>"NodataFilter"</CODE><BR> // * <STRONG>JAI operator:</STRONG> none<BR> // * <STRONG>Parameters:</STRONG></P> // * <table border='3' cellpadding='6' bgcolor='F4F8FF'> // * <tr bgcolor='#B9DCFF'> // * <th>Name</th> // * <th>Class</th> // * <th>Default value</th> // * <th>Minimum value</th> // * <th>Maximum value</th> // * </tr> // * <tr> // * <td>{@code "Source"}</td> // * <td>{@link org.geotools.coverage.grid.GridCoverage2D}</td> // * <td align="center">N/A</td> // * <td align="center">N/A</td> // * <td align="center">N/A</td> // * </tr> // * <tr> // * <td>{@code "padding"}</td> // * <td>{@link java.lang.Integer}</td> // * <td>1</td> // * <td align="center">0</td> // * <td align="center">N/A</td> // * </tr> // * <tr> // * <td>{@code "validityThreshold"}</td> // * <td>{@link java.lang.Integer}</td> // * <td>4</td> // * <td align="center">0</td> // * <td align="center">N/A</td> // * </tr> // * </table> // * // * @since 2.2 // * @source $URL$ // * @version $Id$ // * @author Martin Desruisseaux (IRD) // * // * @see org.geotools.coverage.processing.Operations#nodataFilter(GridCoverage,int,int) // */ //public class NodataFilter extends FilterOperation { // /** // * Serial number for interoperability with different versions. // */ // private static final long serialVersionUID = 6818008657792977519L; // // /** // * Constructs a default {@code "NodataFilter"} operation. // */ // public NodataFilter() { // super("org.geotools.NodataFilter"); // } //}
