Description:

  Read Semper accesses an image file format from the SEMPER image processing
  system. The entire file is read into memory, and sent to the Image output port
  for further processing by other AVS modules. The Y scan line order is
  reversed compared to other AVS images, so the image will appear upside down
  unless reversed with "mirror". The images are generally in "xxx.pic" named file.

   NOTE: The format of this file is unnecessarily restrictive due to the
         simplicity of the header.  The format will be upgraded in the near
         future to accomodate additional information and data types.
