Description

This is a tracking issue for implementing interactive forms.

In order to support interactive forms with partial compliance to PDF 1.7, pdf-writer must first support most of section 12.7 as well as a few other parts of the 1.7 spec which this section depends on. Certain features which are known to be deprecated in specs after 1.7, such as XFA forms, will not be implemented.

Tasks

The following work has to be done, this list will be updated as new issues arise or feature sets are requested/dropped. Some of these features could later be dropped as optional or unneeded.
