| GeoTIFFDirectory | | public class GeoTIFFDirectory extends XTIFFDirectory implements java.io.Serializable(Code) | | An extension of the XTIFFDirectory that understands
the structure of the GeoTIFF key set
author:

| Constructor Summary | |
| public | GeoTIFFDirectory()
| | public | GeoTIFFDirectory(SeekableStream stream, long ifd_offset)
Constructs a GeoTIFFDirectory by reading a SeekableStream. | | public | GeoTIFFDirectory(SeekableStream stream, int directory)
Constructs a GeoTIFFDirectory from a SeekableStream. |
| GeoTIFFDirectory | | public GeoTIFFDirectory()(Code) | | public constructor (for serializability)
|
| GeoTIFFDirectory | | public GeoTIFFDirectory(SeekableStream stream, long ifd_offset) throws java.io.IOException(Code) | | Constructs a GeoTIFFDirectory by reading a SeekableStream.
The ifd_offset parameter specifies the stream offset from
which to begin reading;
this mechanism is sometimes used to store private IFDs within a
TIFF file that are not part of the normal sequence of IFDs.
|
| GeoTIFFDirectory | | public GeoTIFFDirectory(SeekableStream stream, int directory) throws java.io.IOException(Code) | | Constructs a GeoTIFFDirectory from a SeekableStream.
The directory parameter specifies which directory to read
from the linked list present in the stream; directory 0 is
normally read but it is possible to store multiple images
in a single TIFF file by maintaing multiple directories.
|
| addGeoKey | | public void addGeoKey(int key, int type, int count, Object data)(Code) | | Add a geoKey to the directory
|
| addGeoKey | | public void addGeoKey(XTIFFField geoKey)(Code) | | Add an existing geoKey to the directory.
|
| getFields | | public XTIFFField[] getFields()(Code) | | Returns an array of XTIFFFields containing all the fields
in this directory. Prior to returning array, determine if
there are any GeoKeys, and if so, set up the corresponding
GeoTIFF fields.
|
| getGeoKey | | public XTIFFField getGeoKey(int key)(Code) | | Indexed Accessor to the Geokeys,indexed by
the key values.
|
| getGeoKeys | | public XTIFFField[] getGeoKeys()(Code) | | Returns an array of XTIFFFields containing all the fields
corresponding to the GeoKeys.
|
| getPixelScale | | public double[] getPixelScale()(Code) | | return the pixel scale tag values
|
| getTiepoints | | public double[] getTiepoints()(Code) | | return the tiepoint tag values
|
| getTransformationMatrix | | public double[] getTransformationMatrix()(Code) | | return the transformation matrix tag values
|
| setPixelScale | | public void setPixelScale(double[] scales)(Code) | | return the pixel scale tag values
|
| setTiepoints | | public void setTiepoints(double[] tiepoints)(Code) | | set the tiepoint tag values
|
| setTransformationMatrix | | public void setTransformationMatrix(double[] matrix)(Code) | | return the pixel scale tag values
