    • DefaultProcessDiagramCanvas

      public DefaultProcessDiagramCanvas(int width, int height, int minX, int minY, String activityFontName, String labelFontName, String annotationFontName)
      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)
      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 Details

    • initialize

      public void initialize()

    • generateImage

      public InputStream generateImage()
      Generates an image of what currently is drawn on the canvas.

      Throws an ActivitiImageException when close() is already called.

    • close

      public void close()
      Closes the canvas which dissallows further drawing and releases graphical resources.
