    • Constructor Detail

      • DefaultProcessDiagramCanvas

        public DefaultProcessDiagramCanvas​(int width,
                                   int height,
                                   int minX,
                                   int minY,
                                   java.lang.String activityFontName,
                                   java.lang.String labelFontName,
                                   java.lang.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 Detail

      • initialize

        public void initialize()

      • generateImage

        public java.io.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.
