| 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]));
}
