Enum Constants
Enum Constant and Description
`ADD` The color and alpha components from the top input are added to those from the bottom input.
`BLUE` The blue component of the bottom input is replaced with the blue component of the top input; the other color components are unaffected.
`COLOR_BURN` The inverse of the bottom input color components are divided by the top input color components, all of which is then inverted to produce the resulting color.
`COLOR_DODGE` The bottom input color components are divided by the inverse of the top input color components to produce the resulting color.
`DARKEN` The darker of the color components from the two inputs are selected to produce the resulting color.
`DIFFERENCE` The darker of the color components from the two inputs are subtracted from the lighter ones to produce the resulting color.
`EXCLUSION` The color components from the two inputs are multiplied and doubled, and then subtracted from the sum of the bottom input color components, to produce the resulting color.
`GREEN` The green component of the bottom input is replaced with the green component of the top input; the other color components are unaffected.
`HARD_LIGHT` The input color components are either multiplied or screened, depending on the top input color.

`RED` The red component of the bottom input is replaced with the red component of the top input; the other color components are unaffected.
`SCREEN` The color components from both of the inputs are inverted, multiplied with each other, and that result is again inverted to produce the resulting color.
`SOFT_LIGHT` The input color components are either darkened or lightened, depending on the top input color.
`SRC_ATOP` The part of the top input lying inside of the bottom input is blended with the bottom input.
`SRC_OVER` The top input is blended over the bottom input.

- Enum Constant Detail
  - SRC_OVER
```
public static final BlendMode SRC_OVER
```
    The top input is blended over the bottom input. (Equivalent to the Porter-Duff "source over destination" rule.)
  - SRC_ATOP
```
public static final BlendMode SRC_ATOP
```
    The part of the top input lying inside of the bottom input is blended with the bottom input. (Equivalent to the Porter-Duff "source atop destination" rule.)
  - ADD
```
public static final BlendMode ADD
```
    The color and alpha components from the top input are added to those from the bottom input. The result is clamped to 1.0 if it exceeds the logical maximum of 1.0.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode is sometimes referred to as "linear dodge" in imaging software packages.
  - MULTIPLY
```
public static final BlendMode MULTIPLY
```
    The color components from the first input are multiplied with those from the second input. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode is the mathematical opposite of the SCREEN mode.
    - The resulting color is always at least as dark as either of the input colors.
    - Rendering with a completely black top input produces black; rendering with a completely white top input produces a result equivalent to the bottom input.
  - SCREEN
```
public static final BlendMode SCREEN
```
    The color components from both of the inputs are inverted, multiplied with each other, and that result is again inverted to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode is the mathematical opposite of the MULTIPLY mode.
    - The resulting color is always at least as light as either of the input colors.
    - Rendering with a completely white top input produces white; rendering with a completely black top input produces a result equivalent to the bottom input.
  - OVERLAY
```
public static final BlendMode OVERLAY
```
    The input color components are either multiplied or screened, depending on the bottom input color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is a combination of SCREEN and MULTIPLY, depending on the bottom input color.
    - This mode is the mathematical opposite of the HARD_LIGHT mode.
    - In this mode, the top input colors "overlay" the bottom input while preserving highlights and shadows of the latter.
  - DARKEN
```
public static final BlendMode DARKEN
```
    The darker of the color components from the two inputs are selected to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode is the mathematical opposite of the LIGHTEN mode.
  - LIGHTEN
```
public static final BlendMode LIGHTEN
```
    The lighter of the color components from the two inputs are selected to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode is the mathematical opposite of the DARKEN mode.
  - COLOR_DODGE
```
public static final BlendMode COLOR_DODGE
```
    The bottom input color components are divided by the inverse of the top input color components to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
  - COLOR_BURN
```
public static final BlendMode COLOR_BURN
```
    The inverse of the bottom input color components are divided by the top input color components, all of which is then inverted to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
  - HARD_LIGHT
```
public static final BlendMode HARD_LIGHT
```
    The input color components are either multiplied or screened, depending on the top input color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is a combination of SCREEN and MULTIPLY, depending on the top input color.
    - This mode is the mathematical opposite of the OVERLAY mode.
  - SOFT_LIGHT
```
public static final BlendMode SOFT_LIGHT
```
    The input color components are either darkened or lightened, depending on the top input color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is similar to OVERLAY, but generally produces "lighter" results than OVERLAY.
  - DIFFERENCE
```
public static final BlendMode DIFFERENCE
```
    The darker of the color components from the two inputs are subtracted from the lighter ones to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode can be used to invert parts of the bottom input image, or to quickly compare two images (equal pixels will result in black).
    - Rendering with a completely white top input inverts the bottom input; rendering with a completely black top input produces a result equivalent to the bottom input.
  - EXCLUSION
```
public static final BlendMode EXCLUSION
```
    The color components from the two inputs are multiplied and doubled, and then subtracted from the sum of the bottom input color components, to produce the resulting color. The alpha components are blended according to the SRC_OVER equation.
    Notes:
    - This mode is commutative (ordering of inputs does not matter).
    - This mode can be used to invert parts of the bottom input.
    - This mode produces results that are similar to those of DIFFERENCE, except with lower contrast.
    - Rendering with a completely white top input inverts the bottom input; rendering with a completely black top input produces a result equivalent to the bottom input.
  - RED
```
public static final BlendMode RED
```
    The red component of the bottom input is replaced with the red component of the top input; the other color components are unaffected. The alpha components are blended according to the SRC_OVER equation.
  - GREEN
```
public static final BlendMode GREEN
```
    The green component of the bottom input is replaced with the green component of the top input; the other color components are unaffected. The alpha components are blended according to the SRC_OVER equation.
  - BLUE
```
public static final BlendMode BLUE
```
    The blue component of the bottom input is replaced with the blue component of the top input; the other color components are unaffected. The alpha components are blended according to the SRC_OVER equation.
- 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:

    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
