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

    • initialize

      public void initialize(String imageType)

    • generateImage

      public InputStream generateImage(String imageType)
      Generates an image of what currently is drawn on the canvas. Throws an FlowableImageException when close() is already called.

    • generateBufferedImage

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

    • close

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