      Description

        Need a mechanism to display and zoom images of type javafx.scene.image.Image at an application without smoothing.
        Usage of a function:
                          public void drawImage(Image img, double sx, double sy, double sw, double sh, double dx, double dy, double dw, double dh)
                                of class javafx.scene.canvas.GraphicsContext

        results to a smoothing of original image when using different zoom levels. At an application it is essential to see the original content of an image.
        So, is there a way to disable that smoothing and any other filtering?
        Reloading the image should not be required.
