    hue - hue degrees
  - setParameter1
```
 void setParameter1(float value)
```
    Sets the parameter.The value should always be between 0 and 1.
    
    Parameters:
    
    value - parameter
  - getParameter1
```
 float getParameter1()
```
    Returns the parameter.The returned value should always be between 0 and 1.
  - getFragmentShader
```
@NonNull() String getFragmentShader()
```
    Returns a String containing the fragment shader.Together with getVertexShader, this will be used tocreate the OpenGL program.
  - onCreate
```
 void onCreate(int programHandle)
```
    The filter program was just created. We pass in a handle to the OpenGLprogram that was created, so you can fetch pointers.
    
    Parameters:
    
    programHandle - handle
  - onDestroy
```
 void onDestroy()
```
    The filter program is about to be destroyed.
