Class TLcdGeoTIFFField

java.lang.Object
com.luciad.format.raster.TLcdGeoTIFFField
public class TLcdGeoTIFFField extends Object
This class describes a TIFF or GeoTIFF tag and the corresponding field. The tag normally serves as a key. The field then contains a value or a list of values that can be numeric or textual.

The data can be of the following types:

TIFF type Data type
TYPE_ASCII String[]
TYPE_SBYTE byte[]
TYPE_BYTE byte[]
TYPE_SSHORT short[]
TYPE_SHORT char[]
TYPE_SLONG int[]
TYPE_LONG long[]
TYPE_FLOAT float[]
TYPE_DOUBLE double[]
TYPE_SRATIONALint[][]
TYPE_RATIONAL long[][]
TYPE_UNDEFINEDbyte[]
