-- | The X and Y coordinates of a point on a document page. The X and Y
-- values that are returned are ratios of the overall document page size.
-- For example, if the input document is 700 x 200 and the operation
-- returns X=0.5 and Y=0.25, then the point is at the (350,50) pixel
-- coordinate on the document page.
--
-- An array of @Point@ objects, @Polygon@, is returned by
-- DetectDocumentText. @Polygon@ represents a fine-grained polygon around
-- detected text. For more information, see Geometry in the Amazon Textract
-- Developer Guide.
