GeoTiffWriteParams
final public class GeoTiffWriteParams extends GeoToolsWriteParams (Code)
Subclass of GeoToolsWriteParams the allows the user to specify parameters to control the process of writing out a GeoTiff file through standards ImageWriteParam (with possible extensions).

This class allows the user to control the output tile size for the GeoTiff file we are going to create as well as the possible compression.

An example of usage of this parameters is as follows:

 
 //getting a format
 final GeoTiffFormat format = new GeoTiffFormat();
 //getting the write parameters
 final GeoTiffWriteParams wp = new GeoTiffWriteParams();
 //setting compression to LZW
 wp.setCompressionMode(GeoTiffWriteParams.MODE_EXPLICIT);
 wp.setCompressionType("LZW");
 wp.setCompressionQuality(0.75F);
 //setting the tile size to 256X256
 wp.setTilingMode(GeoToolsWriteParams.MODE_EXPLICIT);
 wp.setTiling(256, 256);
 //setting the write parameters for this geotiff
 final ParameterValueGroup params = format.getWriteParameters();
 params.parameter(
 AbstractGridFormat.GEOTOOLS_WRITE_PARAMS.getName().toString())
 .setValue(wp);
 //get a reader to the input File
 GridCoverageReader reader = new GeoTiffReader(inFile, null);
 GridCoverageWriter writer = null;
 GridCoverage2D gc = null;
 if (reader != null) {
 // reading the coverage
 gc = (GridCoverage2D) reader.read(null);
 if (gc != null) {
 final File writeFile = new File(new StringBuffer(writedir
 .getAbsolutePath()).append(File.separatorChar)
 .append(gc.getName().toString()).append(".tiff")
 .toString());
 writer = format.getWriter(writeFile);
 writer.write(gc, (GeneralParameterValue[]) params.values()
 .toArray(new GeneralParameterValue[1]));
 }
