   org.geotools.coverage.grid.io.AbstractGridFormat
      org.geotools.gce.image.WorldImageFormat

WorldImageFormat
final public class WorldImageFormat extends AbstractGridFormat implements Format(Code)
A Format to allow discovery of Readers/Writers for raster images that support world files containing information about the image. Supports gif+gfw, jpg/jpeg+jgw, tif/tiff+tfw and png+pgw. wld may be used in place of the format specific extension (jpg+wld, etc) Designed to be used with GridCoverageExchange.

Field Summary
final public static  ParameterDescriptorFORMAT
     Format writing parameter.

Constructor Summary
public  WorldImageFormat()
    

Method Summary
public  booleanaccepts(Object input)
     Takes the input and determines if it is a class that we can understand and then futher checks the format of the class to make sure we can read/write to it.
Parameters:
  input - The object to check for acceptance.
public  GeoToolsWriteParamsgetDefaultImageIOWriteParameters()
     Always returns null since for the moment there are no GeoToolsWriteParams availaible for this format.
public  GridCoverageReadergetReader(Object source)
     Retrieves a WorldImageReader in case the providede source can be accepted as a valid source for a world image.
public  GridCoverageReadergetReader(Object source, Hints hints)
     Retrieves a WorldImageReader in case the providede source can be accepted as a valid source for a world image.
public static  SetgetWorldExtension(String fileExtension)
     Takes an image file extension (such as .gif, including the '.') and returns it's corresponding world file extension (such as .gfw).
public  GridCoverageWritergetWriter(Object destination)
     Call the accepts() method before asking for a writer to determine if the current object is supported.
public  GridCoverageWritergetWriter(Object destination, Hints hints)
     Call the accepts() method before asking for a writer to determine if the current object is supported.

Field Detail
FORMAT
final public static ParameterDescriptor FORMAT(Code)
Format writing parameter. When writing a world image we need to provide an output format in which we want to encode the image itself. PNG is default output format.
