// as an associated Block of type PAGE. Each PAGE Block object is the parent of
// LINE Block objects that represent the lines of detected text on a page. A LINE
// Block object is a parent for each word that makes up the line. Words are
// represented by Block objects of type WORD. DetectDocumentText is a synchronous
