Method Detail

values

public static BlendComposite.BlendingMode[] 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 (BlendComposite.BlendingMode c : BlendComposite.BlendingMode.values())
    System.out.println(c);

Returns:

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

valueOf

public static BlendComposite.BlendingMode 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

perform

public abstract void perform(int sr,
                             int sg,
                             int sb,
                             int sa,
                             int dr,
                             int dg,
                             int db,
                             int da,
                             int[] result)

Performs the color blending on the given pixels, assuming the source colors are pre-multiplied

getName

public String getName()

lookupByName

public static BlendComposite.BlendingMode lookupByName(String name)

Looks up a blending mode by its SVG standard name (as opposed to the enum name, which for example cannot contain hyphens)

Parameters:

name - The standard name

Returns:

The corresponding blending mode, or null if not found

getStandardNames

public static List<String> getStandardNames()

Returns the list of blending modes standard names

Returns:

The list of blending mode names
