ScaleReplication

```
public class ScaleReplication
extends ImageToImageOperation
```
Changes the pixel resolution of an image by replicating (or dropping) pixels. A fast but low quality scaling algorithm that works with all kinds of image types. Resample provides better quality, but is slower and works with intensity-based image data types only.
Usage example
The input image will be scaled to an image that is twice as wide as itself and three times as high.
```
 ScaleReplication scale = new ScaleReplication();
 scale.setInputImage(image); // something implementing IntegerImage
 scale.setSize(image.getWidth() * 2, image.getHeight() * 2);
 scale.process();
 PixelImage scaledImage = scale.getOutputImage();
 
```

    Description copied from class: Operation
    
    This method does the actual work of the operation. It must be called after all parameters have been given to the operation object.
    
    Overrides:
    
    process in class Operation
    
    Throws:
    
    MissingParameterException - if any mandatory parameter was not given to the operation
    
    WrongParameterException - if at least one of the input parameters was not initialized appropriately (values out of the valid interval, etc.)
  - setSize
```
public void setSize(int width,
                    int height)
```
    Specify the resolution to be used for the image to be created.
    
    Parameters:
    
    width - horizontal resolution of the new image
    
    height - vertical resolution of the new image
    
    Throws:
    
    IllegalArgumentException - if any of the arguments is smaller than 1
