13.15. Unimplemented Features, Known Bugs

Extraction of Field Information

Some properties of form fields are not extracted, for example 'background color', 'border color' und 'border styles'.

Extraction of Signature Information

Currently not all signature data is exported into XML. It is possible that the XML structure will change in future releases.


In the current release 2016.05 colors cannot be tested directly. If colors have to be tested, the test has to be carried out using rendered pages. The sections 3.20: “Layout - Entire PDF Pages” and 3.21: “Layout - in Page Regions” describe such tests.

Content of Layers

Tests related to text and images are not restricted to layers.

Complete XMP data

In the current release only the document-level XMP data are extracted and evaluated.
