- Enum Constant Detail
  - NORMAL
```
public static final BlendMode NORMAL
```
    Selects the source color, ignoring the backdrop.
  - MULTIPLY
```
public static final BlendMode MULTIPLY
```
    Multiplies the backdrop and source color values
    
    The result color is always at least as dark as either of the two constituent colors.
    
    When working with additive colors, multiplying any color with black produces black while multiplying with white leaves the original color unchanged.
    
    For subtractive colors, the maximum tint value used for all colorants of the color space acts as black does for additive spaces.
    
    Painting successive overlapping objects with a color other than black or white produces progressively darker colors.
  - SCREEN
```
public static final BlendMode SCREEN
```
    Multiplies the complements of the backdrop and source color values, then complements the result.
    
    The result color is always at least as light as either of the two constituent colors.
    
    When working with additive colors, screening any color with white produces white while screening with black leaves the original color unchanged.
    
    For subtractive colors, the maximum tint value of all colorants of the color space acts as black does for additive spaces.
    
    The effect is similar to projecting multiple photographic slides simultaneously onto a single screen.
  - DARKEN
```
public static final BlendMode DARKEN
```
    Selects the darker of the backdrop and source colors.
    The backdrop is replaced with the source where the source is darker; otherwise, it is left unchanged.
  - LIGHTEN
```
public static final BlendMode LIGHTEN
```
    Selects the lighter of the backdrop and source colors.
    The backdrop is replaced with the source where the source is lighter; otherwise, it is left unchanged.
  - COLOR_DODGE
```
public static final BlendMode COLOR_DODGE
```
    Brightens the backdrop color to reflect the source color.
    Painting with black produces no change.
  - COLOR_BURN
```
public static final BlendMode COLOR_BURN
```
    Darkens the backdrop color to reflect the source color.
    Painting with white produces no change.
  - HARD_LIGHT
```
public static final BlendMode HARD_LIGHT
```
    Multiplies or screens the colors, depending on the source color value.
    The effect is similar to shining a harsh spotlight on the backdrop.
  - SOFT_LIGHT
```
public static final BlendMode SOFT_LIGHT
```
    Darkens or lightens the colors, depending on the source color value.
    The effect is similar to shining a diffused spotlight on the backdrop.
  - OVERLAY
```
public static final BlendMode OVERLAY
```
    Multiplies or screens the colors, depending on the backdrop color value.
    Source colors overlay the backdrop while preserving its highlights and shadows. The backdrop color is not replaced but is mixed with the source color to reflect the lightness or darkness of the backdrop.
  - DIFFERENCE
```
public static final BlendMode DIFFERENCE
```
    Subtracts the darker of the two constituent colors from the lighter color.
    
    Painting with white inverts the backdrop color; painting with black produces no change.
    
    For subtractive colors, the maximum tint value for all colourants of the color space acts as black does for additive spaces.
    
    This blend mode is not white-preserving.
  - EXCLUSION
```
public static final BlendMode EXCLUSION
```
    Produces an effect similar to that of the Difference mode but lower in contrast.
    
    Painting with white inverts the backdrop color; painting with black produces no change.
    
    For subtractive colors, the maximum tint value for all colourants of the color space acts as black does for additive spaces.
  - HUE
```
public static final BlendMode HUE
```
    Creates a color with the hue of the source color and the saturation and luminosity of the backdrop color.
    This blend mode is not separable.
  - SATURATION
```
public static final BlendMode SATURATION
```
    Creates a color with the saturation of the source color and the hue and luminosity of the backdrop color.
    
    Painting with this mode in an area of the backdrop that is a pure gray (no saturation) produces no change.
    
    This blend mode is not separable.
  - COLOR
```
public static final BlendMode COLOR
```
    Creates a color with the hue and saturation of the source color and the luminosity of the backdrop color.
    
    This preserves the gray levels of the backdrop and is useful for coloring monochrome images or tinting color images.
    
    This blend mode is not separable.
  - LUMINOSITY
```
public static final BlendMode LUMINOSITY
```
    Creates a color with the luminosity of the source color and the hue and saturation of the backdrop color.
    
    This produces an inverse effect to that of the COLOR mode.
    
    This blend mode is not separable.
- Method Detail
  - values
```
public static BlendMode[] 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 (BlendMode c : BlendMode.values())
    System.out.println(c);
```
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static BlendMode valueOf(java.lang.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:
    
    java.lang.IllegalArgumentException - if this enum type has no constant with the specified name
    
    java.lang.NullPointerException - if the argument is null
  - fromValue
```
public static BlendMode fromValue(int value)
```
  - getValue
```
public int getValue()
```
