Comparing to PDF v1.4, 1.5 support JPEG 2000, enhanced support for embedding and playback of multimedia, using XML Forms Data Format (XFDF) for interactive form submission. To get such advantages, we need to implement PDF v1.5 file structure, adding option to expert file as PDF 1.5.
Steps to Reproduce:
User Profile Reset: No
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:55.0) Gecko/20100101 Firefox/55.0
Valid enhancement request. Patches much appreciated.
Best regards. JBF
With this support we are also allowed to import and edit PDF 1.5 file directly.
