PdfConformance Enumeration

In This Topic

Specifies PDF versions and conformance levels of a PDF document.

The PDF versions correspond to the PDF major releases, starting from PDF 1.0. In each PDF version the new features have been introduced. The different conformance levels reflect the quality of the archived document and depend on the input material and the documents purpose. PDF/A versions and levels are given one after another.

PDF/A-1 is the first archiving standard based on PDF version 1.4. All resources must be embedded within the PDF/A document itself.

PDF/A-2 is based on PDF 1.7. It allows JPEG2000 compression, transparent elements, PDF layers and more.

PDF/A-3 is available since October 2012. It allows to embed any file format desired.

Level a (accessible) meets all requirements for the standard.

Level b (basic) guaranteed that the content of the document can be unambiguously reproduced.

Level u (unicode) specifies that all text can be mapped to standard Unicode character codes.
