-- | The bounding box around the detected page, text, key-value pair, table,
-- table cell, or selection element on a document page. The @left@
-- (x-coordinate) and @top@ (y-coordinate) are coordinates that represent
-- the top and left sides of the bounding box. Note that the upper-left
-- corner of the image is the origin (0,0).
--
-- The @top@ and @left@ values returned are ratios of the overall document
-- page size. For example, if the input image is 700 x 200 pixels, and the
-- top-left coordinate of the bounding box is 350 x 50 pixels, the API
-- returns a @left@ value of 0.5 (350\/700) and a @top@ value of 0.25
-- (50\/200).
--
-- The @width@ and @height@ values represent the dimensions of the bounding
-- box as a ratio of the overall document page dimension. For example, if
-- the document page size is 700 x 200 pixels, and the bounding box width
-- is 70 pixels, the width returned is 0.1.
