All Implemented Interfaces:

Serializable, Comparable<Interpolation>, Constable

public enum Interpolation
extends Enum<Interpolation>

Interpolation defines how drawn images are upscaled and downscaled. For more details see Wikipedia Bicubic Interpolation and Wikipedia Image Scaling.

Enum Constant Summary

Enum Constants

Enum Constant	Description
BICUBIC	Bicubic interpolation interpolates pixel using a cubic equation.
BILINEAR	Bilinear interpolation interpolates pixel values via linear equations.
NEAREST_NEIGHBOR	When increasing or decreasing the size of an image the nearest neighbor is picked to color a pixel.

Method Summary

Modifier and Type	Method	Description

Enum Constant Details

NEAREST_NEIGHBOR

public static final Interpolation NEAREST_NEIGHBOR

When increasing or decreasing the size of an image the nearest neighbor is picked to color a pixel. Sharpness of edges is preserved but images can look very jagged.

BILINEAR

public static final Interpolation BILINEAR

Bilinear interpolation interpolates pixel values via linear equations. Bilinear reduces contrast and makes images appear less sharp.

BICUBIC

public static final Interpolation BICUBIC

Bicubic interpolation interpolates pixel using a cubic equation. Bicubic interpolation usually looks pretty good and smooth, but is slow.

Method Details

values

public static Interpolation[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

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

valueOf

public static Interpolation valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (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 class has no constant with the specified name

NullPointerException - if the argument is null
