Enum Constant Summary

ASCII
8-bit byte that contains a 7-bit ASCII code; the last byte must be NUL (binary zero).

BYTE
8-bit unsigned integer.

DOUBLE
Double precision (8-byte) IEEE format.

FLOAT
Single precision (4-byte) IEEE format.

IFD
32-bit (4-byte) unsigned integer pointing to another IFD, as defined in TIFF Tech Note 1 in TIFF Specification Supplement 1.

LONG
32-bit (4-byte) unsigned integer.

RATIONAL
Two LONGs: the first represents the numerator of a fraction; the second, the denominator.

SBYTE
An 8-bit signed (twos-complement) integer.

SHORT
16-bit (2-byte) unsigned integer.

SLONG
A 32-bit (4-byte) signed (twos-complement) integer.

SRATIONAL
Two SLONG’s: the first represents the numerator of a fraction, the second the denominator.

SSHORT
A 16-bit (2-byte) signed (twos-complement) integer.

UNDEFINED
An 8-bit byte that may contain anything, depending on the definition of the field.

Method Detail

values

public static IFDDataType[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (IFDDataType c : IFDDataType.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IFDDataType valueOf(java.lang.String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

java.lang.IllegalArgumentException - if this enum type has no constant with the specified name

java.lang.NullPointerException - if the argument is null

getTypeNumber

public int getTypeNumber()

valueOf

public static IFDDataType valueOf(int typeNumber)

Gets the tag for the specified value.
