@Generated("io.github.jwharm.JavaGI")
public enum InterpType
extends Enum<InterpType>
implements Enumeration

Interpolation modes for scaling functions.

The GDK_INTERP_NEAREST mode is the fastest scaling method, but has horrible quality when scaling down; GDK_INTERP_BILINEAR is the best choice if you aren't sure what to choose, it has a good speed/quality balance.

**Note**: Cubic filtering is missing from the list; hyperbolic interpolation is just as fast and results in higher quality.

Enum Constant Summary

Enum Constants

Enum Constant	Description
BILINEAR	Best quality/speed balance; use this mode by default.
HYPER	This is the slowest and highest quality reconstruction function.
NEAREST	Nearest neighbor sampling; this is the fastest and lowest quality mode.
TILES	This is an accurate simulation of the PostScript image operator without any interpolation enabled.

Enum Constant Details

NEAREST

public static final InterpType NEAREST

Nearest neighbor sampling; this is the fastest and lowest quality mode. Quality is normally unacceptable when scaling down, but may be OK when scaling up.

TILES

public static final InterpType TILES

This is an accurate simulation of the PostScript image operator without any interpolation enabled. Each pixel is rendered as a tiny parallelogram of solid color, the edges of which are implemented with antialiasing. It resembles nearest neighbor for enlargement, and bilinear for reduction.

BILINEAR

public static final InterpType BILINEAR

Best quality/speed balance; use this mode by default. Bilinear interpolation. For enlargement, it is equivalent to point-sampling the ideal bilinear-interpolated image. For reduction, it is equivalent to laying down small tiles and integrating over the coverage area.

HYPER

public static final InterpType HYPER

This is the slowest and highest quality reconstruction function. It is derived from the hyperbolic filters in Wolberg's "Digital Image Warping", and is formally defined as the hyperbolic-filter sampling the ideal hyperbolic-filter interpolated image (the filter is designed to be idempotent for 1:1 pixel mapping). **Deprecated**: this interpolation filter is deprecated, as in reality it has a lower quality than the GDKINTERPBILINEAR filter (Since: 2.38)

Method Details

values

public static InterpType[] 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 InterpType 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

of

public static InterpType of(int value)

Create a new InterpType for the provided value

Parameters:

value - the enum value

Returns:

the enum for the provided value

getValue

public int getValue()

Get the numeric value of this enum

Specified by:

getValue in interface Enumeration

Returns:

the enum value

getType

public static Type getType()

Get the GType of the InterpType class

Returns:

the GType
