SimpleFilter

All Implemented Interfaces:

com.otaliastudios.cameraview.filter.Filter
```
public final class SimpleFilter
extends BaseFilter
                    
```
The simplest possible filter that accepts a fragment shader in its constructor. This can be used when your fragment shader is static and has no 'runtime' parameters that influence its behavior. The given fragment shader should respect the default variable names, as listed in the BaseFilter class. NOTE: SimpleFilter is not meant to be subclassed! Subclassing it would require you to override onCopy, which would make this class useless. Instead, you can extend BaseFilter directly.
