module Axlsx

  # A BookView defines the display properties for a workbook.
  # Units for window widths and other dimensions are expressed in twips.
  # Twip measurements are portable between different display resolutions.
  # The formula is (screen pixels) * (20 * 72) / (logical device dpi),
  # where the logical device dpi can be different for x and y coordinates.
