Detailed Description

PDF structure tree is a kind of common data structure in tagged PDF documents. A structure tree is used in PDF files to represent the organization and hierarchy of the document's content. PDF structure tree has following characteristics:

  • A PDF structure tree is also a hierarchical structure, with the top node representing the entire document and the lower nodes representing pages, paragraphs, headings, and other elements.
  • A PDF structure tree contains semantic information about the content of the document, such as headings, paragraphs, tables, and lists. This information is used to enhance the accessibility and usability of the document, as well as to optimize its display and printing;

Class PDFStructTree is used to be associated with an existing PDF structure tree. It offers functions to get structure elements in the PDF structure tree.
