  - exportDiagram
```
ImageData exportDiagram(java.io.OutputStream os,
                        int num,
                        FileFormatOption fileFormat)
                 throws java.io.IOException
```
    Export the diagram as an image to some format. Note that a diagram could be drawn as several images (think about new page for sequence diagram for example).
    
    Parameters:
    
    os - where to write the image
    
    num - usually 0 (index of the image to be exported for this diagram).
    
    fileFormat - file format to use
    
    Returns:
    
    a description of the generated image
    
    Throws:
    
    java.io.IOException
  - getNbImages
```
int getNbImages()
```
    Number of images in this diagram (usually, 1)
    
    Returns:
    
    usually 1
  - getDescription
```
DiagramDescription getDescription()
```
  - getMetadata
```
java.lang.String getMetadata()
```
  - getWarningOrError
```
java.lang.String getWarningOrError()
```
  - getSource
```
UmlSource getSource()
```
    The original source of the diagram
    
    Returns:
