```
public class Histogram3DCreator
extends Operation
```
This class creates three-dimensional histograms for images with integer samples. Only IntegerImage is supported. Existing histogram objects can be given to this operation to be reused.
Note: Before JIU 0.10.0 there was a single HistogramCreator class.

Since:

0.10.0

public static Integer count(IntegerImage image)
```
    Static convenience method to count the number of colors in any three channel IntegerImage object.
    
    Parameters:
    
    image - the IntegerImage whose number of used colors is to be determined
    
    Returns:
    
    the number of colors or null on failure (image does not have three channels, etc.)
    
    Since:
    
    0.15.0
  - createHistogramIfNecessary
```
private void createHistogramIfNecessary()
```
  - getHistogram
```
public Histogram3D getHistogram()
```
    Returns the histogram initialized in this operation.
  - process
```
public void process()
             throws MissingParameterException,
                    WrongParameterException
```
    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.)
  - setHistogram3D
```
public void setHistogram3D(Histogram3D histogram)
```
    Sets the histogram object to be reused for this operation. If this method is not called, a new histogram will be created.
    
    Parameters:
    
    histogram - the histogram object to be used in this operation
  - setImage
```
public void setImage(IntegerImage newImage)
```
    The image for which a histogram will be initialized. Simply calls setImage(IntegerImage, int, int, int) with 0, 1 and 2 as parameters.
    
    Parameters:
    
    newImage - the image for the histogram initialization
  - setImage
```
public void setImage(IntegerImage newImage,
                     int channelIndex1,
                     int channelIndex2,
                     int channelIndex3)
```
    The image for which a histogram will be initialized. Simply calls setImage(IntegerImage, int, int, int) with 0, 1 and 2 as parameters.
    
    Parameters:
    
    newImage -
