      Zoom operations that are handled by ij.plugin.Zoom

    • zoomIn

      public void zoomIn(int sx, int sy)

      zoomIn in class ImageCanvas

      public void unzoom()
      Implements the Image/Zoom/Original Scale command. Sets the original range of the x, y axes (unless the plot is frozen)

      unzoom in class ImageCanvas

    • zoom100Percent

      public void zoom100Percent()
      Implements the Image/Zoom/View 100% command: Sets the original frame size as specified in Edit/Options/Plots (unless the plot is frozen)

      public void fitToWindow()
      Resizes the plot (unless frozen) to fit the window

      setSourceRect in class ImageCanvas

    • setupScroll

      protected void setupScroll(int ox, int oy)
