Enum Constant Summary

Enum Constants
Enum Constant and Description
`DST_IN` Keeps the destination pixels that cover source pixels, discards the remaining source and destination pixels.
`DST_OUT` Keeps the destination pixels that are not covered by source pixels.
`DST_OVER` The source pixels are drawn behind the destination pixels.
`MULTIPLY` Multiplies the source and destination pixels.
`PLUS` Adds the source pixels to the destination pixels and saturates the result.
`SCREEN` Adds the source and destination pixels, then subtracts the source pixels multiplied by the destination.
`SRC` The source pixels replace the destination pixels.
`SRC_IN` Keeps the source pixels that cover the destination pixels, discards the remaining source and destination pixels.
`SRC_OVER` The source pixels are drawn over the destination pixels.

  - DST_IN
```
public static final BlendMode DST_IN
```
    Keeps the destination pixels that cover source pixels, discards the remaining source and destination pixels.
    \(\alpha_{out} = \alpha_{src} * \alpha_{dst}\)
    \(C_{out} = C_{dst} * \alpha_{src}\)
  - DST_OUT
```
public static final BlendMode DST_OUT
```
    Keeps the destination pixels that are not covered by source pixels. Discards destination pixels that are covered by source pixels. Discards all source pixels.
    \(\alpha_{out} = (1 - \alpha_{src}) * \alpha_{dst}\)
    
    \(C_{out} = (1 - \alpha_{src}) * C_{dst}\)
  - DST_OVER
```
public static final BlendMode DST_OVER
```
    The source pixels are drawn behind the destination pixels.
    \(\alpha_{out} = \alpha_{dst} + (1 - \alpha_{dst}) * \alpha_{src}\)
    \(C_{out} = C_{dst} + (1 - \alpha_{dst}) * C_{src}\)
  - MULTIPLY
```
public static final BlendMode MULTIPLY
```
    Multiplies the source and destination pixels.
    \(\alpha_{out} = \alpha_{src} + \alpha_{dst} - \alpha_{src} * \alpha_{dst}\)
    \(C_{out} = C_{src} * (1 - \alpha_{dst}) + C_{dst} * (1 - \alpha_{src}) + (C_{src} * C_{dst})\)
  - PLUS
```
public static final BlendMode PLUS
```
    Adds the source pixels to the destination pixels and saturates the result.
    \(\alpha_{out} = max(0, min(\alpha_{src} + \alpha_{dst}, 1))\)
    
    \(C_{out} = max(0, min(C_{src} + C_{dst}, 1))\)
  - SCREEN
```
public static final BlendMode SCREEN
```
    Adds the source and destination pixels, then subtracts the source pixels multiplied by the destination.
    \(\alpha_{out} = \alpha_{src} + \alpha_{dst} - \alpha_{src} * \alpha_{dst}\)
    \(C_{out} = C_{src} + C_{dst} - C_{src} * C_{dst}\)
  - SRC
```
public static final BlendMode SRC
```
    The source pixels replace the destination pixels.
    \(\alpha_{out} = \alpha_{src}\)
    \(C_{out} = C_{src}\)
  - SRC_IN
```
public static final BlendMode SRC_IN
```
    Keeps the source pixels that cover the destination pixels, discards the remaining source and destination pixels.
    \(\alpha_{out} = \alpha_{src} * \alpha_{dst}\)
    \(C_{out} = C_{src} * \alpha_{dst}\)
  - SRC_OVER
```
public static final BlendMode SRC_OVER
```
    The source pixels are drawn over the destination pixels.
    \(\alpha_{out} = \alpha_{src} + (1 - \alpha_{src}) * \alpha_{dst}\)
    \(C_{out} = C_{src} + (1 - \alpha_{src}) * C_{dst}\)
- Method Detail
  - valueOf
```
public static BlendMode 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
  - 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
