Note: Layout reconstruction varies depending on document and may not be 100% accurate. PDF2ID does not support Type 3 fonts and user-defined dictionaries embedded in PDF files. Moreover, PDF2ID does not perform Optical Character Recognition/Analysis. Scanned pages of printouts stored in PDF documents are usually images. PDF2ID therefore treats such data as images. It also does not process PDF forms, graphics filters, 3D data in PDF files, JBIG2 images and certain graphics operations. JPEG2000 images are supported only in the Macintosh version of PDF2ID. Finally, PDF2ID doesn't process externally linked files or embedded fonts.
