                                                               boolean allowSystem)
                                                        throws java.io.IOException
        Creates an image from a location, suitable for use with this window.

        This method is potentially time-consuming, and should not be invoked on the Event Dispatch Thread.

        Parameters:
        location - file or URL
        allowSystem - whether to allow system commands in location specification - has security implications
        Returns:
        image
        Throws:
        java.io.IOException
      • setImage

        public void setImage​(java.awt.Image image)
        Synchronously configures this window to display an image.

        This method must be invoked from the Event Dispatch Thread.

        Parameters:
        image - image to install
      • resizeToFitImage

        public void resizeToFitImage()
        Resizes this window so that it's the right size to display the current image without scrolling.
      • setImagePoint

        public void setImagePoint​(java.awt.Image image,
                                  java.awt.Point point)
        Synchronously configures this window to display an image and indicate a given X,Y point on it.
        Parameters:
        image - image to install
        point - highlight point
      • setImage

        public void setImage​(java.lang.String location,
                             boolean allowSystem)
        Sets the image to load from a given location. This should be called from the event dispatch thread, but will do most of the work out-of-thread to prevent blocking when loading an image.
        Parameters:
        location - image filename or URL
        allowSystem - whether to allow system commands in location specification - has security implications
