The parameter specifies the source <A HREF="../../../../../org/geotools/coverage/GridSampleDimension.html" title="class in org.geotools.coverage"><CODE>GridSampleDimension</CODE></A> indices, and its size () determines the number of sample dimensions of the destination grid coverage. The destination coverage may have any number of sample dimensions, and a particular sample dimension of the source coverage may be repeated in the destination coverage by specifying it multiple times in the parameter. <p> <strong>Geotools extension:</strong><br> This operation can also be used for selecting a different "visible sample dimension". Some images may contain useful data in more than one sample dimension, but renderer the content using only 1 sample dimension at time. The parameter can be used for selecting this sample dimension. If ommited, then the new grid coverage will inherit its source's visible sample dimension. <P><STRONG>Name:</STRONG> <CODE>"SelectSampleDimension"</CODE><BR> <STRONG>JAI operator:</STRONG> <CODE>"<A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/operator/BandSelectDescriptor.html" title="class or interface in javax.media.jai.operator">BandSelect</A>"</CODE><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></td> <td><A HREF="../../../../../org/geotools/coverage/grid/GridCoverage2D.html" title="class in org.geotools.coverage.grid"><CODE>GridCoverage2D</CODE></A></td> <td align="center">N/A</td> <td align="center">N/A</td> <td align="center">N/A</td> </tr> <tr> <td></td> <td></td> <td align="center">Same as source</td> <td align="center">N/A</td> <td align="center">N/A</td> </tr> <tr> <td></td> <td><A HREF="http://java.sun.com/j2se/1.4/docs/api/java/lang/Integer.html" title="class or interface in java.lang"><CODE>Integer</CODE></A></td> <td align="center">Same as source</td> <td align="center">0</td> <td align="center">N/A</td> </tr> </table><P><P><DL><DT><B>Since:</B></DT> <DD>2.2</DD><DT><B>Author:</B></DT> <DD>Martin Desruisseaux</DD><DT><B>See Also:</B><DD><A HREF="../../../../../org/geotools/coverage/processing/Operations.html#selectSampleDimension(org.opengis.coverage.Coverage, int[])"><CODE>Operations.selectSampleDimension(org.opengis.coverage.Coverage, int[])</CODE></A>, <A HREF="http://java.sun.com/products/java-media/jai/forDevelopers/jai-apidocs/javax/media/jai/operator/BandSelectDescriptor.html" title="class or interface in javax.media.jai.operator"><CODE>BandSelectDescriptor</CODE></A>, <A HREF="../../../../../serialized-form.html#org.geotools.coverage.processing.operation.SelectSampleDimension">Serialized Form</A><DT><B>Module:</B></DT><DD><CODE><B>module/coverage</B></CODE> (<A HREF="http://maven.geotools.fr/repository/org/geotools/gt2-coverage/"><CODE>gt2-coverage.jar</CODE></A>) (<A HREF="http://maven.geotools.fr/reports/coverage/index.html">Maven report</A>) (<A HREF="http://svn.geotools.org/geotools/tags/2.3.2/module/coverage/src/org/geotools/coverage/processing/operation/SelectSampleDimension.java">SVN head</A>)</DD></DL><HR><P><!-- ======== NESTED CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A NAME="field_summary"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#CCCCFF" CLASS="TableHeadingColor"><TD COLSPAN=2><FONT SIZE="+2"><B>Field Summary</B></FONT></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static ParameterDescriptor</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/geotools/coverage/processing/operation/SelectSampleDimension.html#SAMPLE_DIMENSIONS">SAMPLE_DIMENSIONS</A></B></CODE><BR> The parameter descriptor for the sample dimension indices.</TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD ALIGN="right" VALIGN="top" WIDTH="1%"><FONT SIZE="-1"><CODE>static ParameterDescriptor</CODE></FONT></TD><TD><CODE><B><A HREF="../../../../../org/geotools/coverage/processing/operation/SelectSampleDimension.html#VISIBLE_SAMPLE_DIMENSION">VISIBLE_SAMPLE_DIMENSION</A></B></CODE><BR> The parameter descriptor for the visible dimension indice. </TD></TR></TABLE> <A NAME="fields_inherited_from_class_Operation2D"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class <A HREF="../../../../../org/geotools/coverage/processing/Operation2D.html" title="class in org.geotools.coverage.processing">Operation2D</A></B></TD></TR><TR BGCOLOR="white" CLASS="TableRowColor"><TD><CODE><A HREF="../../../../../org/geotools/coverage/processing/Operation2D.html#SOURCE_0">SOURCE_0</A></CODE></TD></TR></TABLE> <A NAME="fields_inherited_from_class_AbstractOperation"><!-- --></A><TABLE BORDER="1" WIDTH="100%" CELLPADDING="3" CELLSPACING="0" SUMMARY=""><TR BGCOLOR="#EEEEFF" CLASS="TableSubHeadingColor"><TD><B>Fields inherited from class <A HREF="../../../../../org/geotools/coverage/processing/AbstractOperation.html" title="class in org.geotools.coverage.processing">AbstractOperation</A></B></TD></TR>⌨️ 快捷键说明
