      private ZoomDragPane(javafx.scene.image.Image image, double prefWidth, double prefHeight)
      Create a Pane container for an ImageView which encapsulates all the Zoom, Drag 无效输入：'&' Rotation logic for an Image.
      参数:
      image - the Image to be displayed
      prefWidth - the desired width of the Pane
      prefHeight - the desired height of the Pane

  • 方法详细资料

    • setMouseDraggedEventHandler

      private void setMouseDraggedEventHandler()
      Drag the Viewport as the Mouse is moved.

    • zoom

      private void zoom(javafx.scene.input.ScrollEvent scrollEvent)
      Zoom Event-Handler. Zooms In or Out exactly 1 Level (if at all).

      Note.: the X-/Y-Coordinates returned by the ScrollEvent are relative-to-the-ImageView and need to be normalised to relative-to-the-Image for the Zoom 无效输入：'&' Viewport calculations.

      参数:
      scrollEvent -

    • zoomCalculateNewViewportXY

      private javafx.geometry.Point2D zoomCalculateNewViewportXY(javafx.geometry.Point2D imageMouse, double scale)
      To fix the Pixel @ the Mouse X-coordinate, the following is true:
      (x - newViewportMinX) / (x - currentViewportMinX) = scale

      The new Viewport X-coordinate is therefore given by:
      newViewportMinX = x - (x - currentViewportMinX) * scale

      The new Viewport Y-coordinate is calculated similarly.

      参数:
      imageMouse - the Mouse coordinates relative to the Image
      scale - the Zoom-factor
      返回:
      X-/Y-coordinate of the new Viewport
      (which setImageViewport(double, double, double, double) will bring into Range if necessary)

    • zoomCalculateViewportSize

      private javafx.geometry.Dimension2D zoomCalculateViewportSize(int zoomLevel)
      Calculate the Viewport size for a particular zoomLevel.
      参数:
      zoomLevel - the Zoom Level
      返回:

    • zoomInCentredToLevel

      private void zoomInCentredToLevel(int zoomLevel)
      Zoom in to the requested zoomLevel.
      (the Viewport will be centred within the Image)
      参数:
      zoomLevel -

    • imageViewToImage

      private javafx.geometry.Point2D imageViewToImage(double viewX, double viewY)
      Calculate Mouse coordinates within the Image based on coordinates within the ImageView.
      参数:
      viewX - X-coordinate of the Mouse within the ImageView
      viewY - Y-coordinate of the Mouse within the ImageView
      返回:
      Coordinates of the Mouse within the Image

    • setImageViewport

      private void setImageViewport(double x, double y, double width, double height)
      Store the new Coordinates 无效输入：'&' Size in the Viewport.
      (making sure that the Viewport remains within the Image)
      参数:
      x -

    • rotateOrReset

      private void rotateOrReset(double relativeRotation)
      The Image will either be rotated or the rotation will be reset to zero.

      Note: this rotation logic was conceived for multiples of 90 degrees.
      It can, however, handle any angle, but the rotation90scale logic would need a touch of Pythagoras.

      参数:
      relativeRotation - the rotation angle, in Degrees (0 = reset to zero)
