Constructor Detail
- DefaultProcessDiagramCanvas
```
public DefaultProcessDiagramCanvas(int width,
                           int height,
                           int minX,
                           int minY,
                           String imageType,
                           String activityFontName,
                           String labelFontName,
                           ClassLoader customClassLoader)
```
  Creates an empty canvas with given width and height. Allows to specify minimal boundaries on the left and upper side of the canvas. This is useful for diagrams that have white space there. Everything beneath these minimum values will be cropped. It's also possible to pass a specific font name and a class loader for the icon images.
- DefaultProcessDiagramCanvas
```
public DefaultProcessDiagramCanvas(int width,
                           int height,
                           int minX,
                           int minY,
                           String imageType)
```
  Creates an empty canvas with given width and height. Allows to specify minimal boundaries on the left and upper side of the canvas. This is useful for diagrams that have white space there (eg Signavio). Everything beneath these minimum values will be cropped.
  
  Parameters:
  minX - Hint that will be used when generating the image. Parts that fall below minX on the horizontal scale will be cropped.
  minY - Hint that will be used when generating the image. Parts that fall below minX on the horizontal scale will be cropped.

Method Detail

initialize

public void initialize(String imageType)

generateImage
```
public InputStream generateImage(String imageType)

public BufferedImage generateBufferedImage(String imageType)
```
Generates an image of what currently is drawn on the canvas. Throws an ActivitiException when close() is already called.

close
```
