Enum Constant Summary

Enum Constants

Enum Constant and 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.

Enum Constant Detail

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 Detail

values

public static ImageUtils.ScalingStrategy[] 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 (ImageUtils.ScalingStrategy c : ImageUtils.ScalingStrategy.values())
    System.out.println(c);

Returns:

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

valueOf

public static ImageUtils.ScalingStrategy 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
