You can affix the following annotation items to the display so that they remain stationary when you rotate, view, or zoom:

  • Text
  • Symbols
  • Classification legends
  • Color bars
  • Scale bars

The following image contains four annotation items: grid lines, text, classification legend, and scale bar.

To make one annotation item stationary, double-click its name in the Layer Manager. In the Edit Properties dialog, set the On The Glass property to True. The following screen capture shows an example of setting this property for the classification legend only:

When you zoom, pan, and/or rotate the image, the classification legend remains stationary. Its font size also remains the same. The image, text, grid lines, and scale bar move as a group, and their sizes scale accordingly when you zoom in or out.

You can also right-click on the top-level annotation layer in the Layer Manager and enable the On The Glass option. This enables the On the Glass property for all supported annotation items in that layer. In this example, the supported annotation items are the text, scale bar, and classification legend.

When you zoom, pan, and/or rotate the image, the scale bar, classification legend, and text remain stationary. Their font size also remains the same. The image and grid lines move as a group, and their sizes scale accordingly when you zoom in or out.
