Import & Export Annotations

 

XFDF is an XML-based standard from Adobe XFDF for encoding annotations. An XFDF file will contain a snapshot of a PDF document’s annotations and forms. It’s compatible with Adobe Acrobat and several other third-party frameworks. ComPDFKit supports both reading and writing XFDF.

 

Importing from XFDF

 

You can import annotations and form fields from an XFDF file to a document like so:

CPDFDocument document = readerView.getPDFDocument();
//the path of xfdf
String xfdfPath = context.getCacheDir() + "/xfdf/exportXFDF.xfdf";
//the transfer path of audio and video files
String tmpxfdfPath = context.getCacheDir() + "/tmp";
document.importAnnotations(xfdfPath,tmpxfdfPath);
readerView.reloadPages();

 

Exporting to XFDF

 

You can export annotations and form fields from a document to an XFDF file like so:

CPDFDocument document = readerView.getPDFDocument();
//the path of xfdf
String xfdfPath = context.getCacheDir() + "/xfdf/exportXFDF.xfdf";
//the transfer path of audio and video files
String tmpxfdfPath = context.getCacheDir() + "/tmp";
document.exportAnnotations(xfdfPath,tmpxfdfPath);
