All Implemented Interfaces:

Serializable, Comparable<ExifTool.Format>

Enclosing class:

ExifTool

public static enum ExifTool.Format
extends Enum<ExifTool.Format>

Enum used to define the 2 different output formats that ExifTool.Tag values can be returned in: numeric or human-readable text.

ExifTool, via the -n command line arg, is capable of returning most values in their raw numeric form (e.g. Aperture="2.8010323841") as well as a more human-readable/friendly format (e.g. Aperture="2.8").

While the ExifTool.Tags defined on this class do provide a hint at the type of the result (see ExifTool.Tag.getType()), that hint only applies when the NUMERIC form of the value is returned.

If the caller finds the human-readable format easier to process, HUMAN_READABLE can be specified when calling ExifTool.getImageMeta(File, Format, Tag...) and the returned String values processed manually by the caller.

In order to see the types of values that are returned when HUMAN_READABLE is used, you can check the comprehensive ExifTool Tag Guide.

This makes sense with some values like Aperture that in NUMERIC format end up returning as 14-decimal-place, high precision values that are near the intended value (e.g. "2.79999992203711" instead of just returning "2.8"). On the other hand, other values (like Orientation) are easier to parse when their numeric value (1-8) is returned instead of a much longer friendly name (e.g. "Mirror horizontal and rotate 270 CW").

Method Detail

values

public static ExifTool.Format[] 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 (ExifTool.Format c : ExifTool.Format.values())
    System.out.println(c);

Returns:

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

valueOf

public static ExifTool.Format valueOf(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:

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

NullPointerException - if the argument is null
