The <Array_2D_Image> is a specialization of the Array_2D class. Use it for data that is primarily intended for visual display, or for analysis by image processing tools.

For an Array_2D_Image, follow the instructions for Filling Out the Array_2D Data Structure, with the following additional constraints/requirements:

  • Use <Array_2D_Image> and </Array_2D_Image> rather than <Array_2D> and </Array_2D>
  • In the <Axis_Array> classes, one must have an <axis_name> of Line, and the other must have an <axis_name> of Sample
  • You absolutely must include a <Display_Settings> class for this object in the <Discipline_Area> of the label. The <Display Settings> class comes from the Display Discipline Dictionary. See Filling Out the Display Dictionary Classes for more information.
