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 tool.

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 a <name> of Lines, and the other must have a <name> of Samples
  • After all the Array_2D classes, you must include a Display_2D_Image class, below.
Note: This <name> attribute requirement above looks like it might only be documented in the Schematron file. I'll need to check this.



This class indicates how the stored data should be drawn on a display device once it has been read into program memory.



This attribute must have one of the values Up or Down, indicating that line should be drawn bottom-to-top or top-to-bottom, respectively.



This attribute must have the value Right, indicating that each individual image line must be drawn from left to right.
