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.

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)

PdfProcessing: ArgumentException is thrown when importing a document with a duplicated filed names.

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

A shading dictionary specifies details of a particular gradient fill, including the
type of shading to be used, the geometry of the area to be shaded, and the geometry of the gradient fill. Various shading types are available, depending on the value of the dictionary’s ShadingType entry:

• Coons patch meshes (type 6) construct a shading from one or more color
  patches, each bounded by four cubic Bézier curves.

This error happens when importing a document.

Multiple graphic state objects are lost on import.

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'.'

InvalidCastException is thrown due to incorrectly parsed stream dictionary.

ArgumentOutOfRangeException is thrown when creating a CapPathRound for an SVG element.

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

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.

InvalidCastException is thrown when importing a document with an annotation declared in the Fields collection.

I have a simple program that imports a PDF, calls AcroForm.FlattenFormFields(), and calls Export() on the PdfFormatProvider. I am seeing the following exception during Import() on a signed W9 form a customer has uploaded into our system. Due to the sensitive nature of the document I cannot upload it, but below is the Sig section. I have tried other example signed PDFs which seem to work fine (See attached)
