Enum Constant Summary

Enum Constants

Enum Constant	Description
AUTO	Automatically determine the best strategy to get the nicest looking image in the least amount of time.
BEST_QUALITY	Do everything possible to make the scaled image exceptionally good, regardless of the processing time needed.
QUALITY	Create a nice scaled version of an image at the cost of more processing time.
SPEED	Scale as fast as possible.
SPEED_AND_QUALITY	Scale faster than when using QUALITY but get better results than when using SPEED.

Method Summary

Modifier and Type	Method	Description
static ImageUtils.ScalingStrategy	valueOf(String name)	Returns the enum constant of this class with the specified name.
static ImageUtils.ScalingStrategy[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

AUTO

public static final ImageUtils.ScalingStrategy AUTO

Automatically determine the best strategy to get the nicest looking image in the least amount of time.

SPEED

public static final ImageUtils.ScalingStrategy SPEED

Scale as fast as possible. For smaller images (800px in size) this can result in noticeable aliasing but it can be a few order of magnitudes faster than using the QUALITY method.

SPEED_AND_QUALITY

public static final ImageUtils.ScalingStrategy SPEED_AND_QUALITY

Scale faster than when using QUALITY but get better results than when using SPEED.

QUALITY

public static final ImageUtils.ScalingStrategy QUALITY

Create a nice scaled version of an image at the cost of more processing time. This strategy is most important for smaller pictures (800px or smaller) and less important for larger pictures, as the difference between this strategy and the SPEED strategy become less and less noticeable as the source-image size increases.

BEST_QUALITY

public static final ImageUtils.ScalingStrategy BEST_QUALITY

Do everything possible to make the scaled image exceptionally good, regardless of the processing time needed. Use this strategy when even @{link #QUALITY} results in bad-looking images.

Method Details

values

public static ImageUtils.ScalingStrategy[] 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 ImageUtils.ScalingStrategy 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
