When exporting the PDF content to plain text, the form fields and their values are not extracted. It would be nice to have an option to include the content in the form fields as well.

Exporting a specific PDF file generates large amounts of ExtGState entries, which results in large file sizes.

When importing a document with a missing "endobj" operator, an exception is thrown: InvalidCastException: 'Unable to cast object of type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfInt' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.IndirectObject'.'

Multiple graphic state objects are lost on import.

Wrong clipping order when exporting a document with MarkedContent leads to a missing content.

Purpose: Long-term archiving of electronic documents with full semantic structure.

• "A" for Archiving

• Level "1a" ensures:

  • Tagged PDF (with proper logical structure and reading order)

  • Unicode text for proper text extraction and searchability

  • Embedded fonts (for consistent rendering)

• Restrictions:

  • No audio/video

  • No encryption

  • No JavaScript

  • No external content (everything must be self-contained)

• Based on: PDF 1.4 (Acrobat 5)

Part 3 of the standard, published on October 15, 2012, differs from PDF/A-2 in only one regard: it allows embedding of arbitrary file formats (such as XML, CSV, CAD, word-processing documents, spreadsheet documents, and others) into PDF/A conforming documents.

Such a document can be considered as invalid. However, it would be good to provide functionality to handle it.
