Save Annotations in individual FDF Files

[Pulkit Goyal]

Hi Team,

I am creating a sample application where the comments and annotations on a PDF made by one user, needs to be viewed in a list and can also be shared with other user on the same platform. So far I have extracted the annotations made on a PDF file as FDF file format but the problem is that it generates one FDF file for all the annotations wherein the User can select a singe annotation to be shared individually.

Is there a method by which for each annotation, a separate FDF file is created?

Else, can I extract individual annotations from a single FDF file? Is there any alternative method to achieve this is Syncfusion

Thanks for your help.

Hi Pulkit, 

Thank you for contacting Syncfusion support.  

We can export individual annotation data from a single PDF document. Please refer the below code snippet for more details, 

//Loaded PDF document to export 

PdfLoadedDocument document = new PdfLoadedDocument(@"Input.pdf"); 

 

int i = 0; 

foreach (PdfLoadedPage loadedPage in document.Pages) 

{ 

    foreach (PdfLoadedAnnotation item in loadedPage.Annotations) 

    { 

        //Collection to export selected annotations 

        PdfExportAnnotationCollection collection = new PdfExportAnnotationCollection(); 

        //Add selected annotations into collection 

        collection.Add(item); 

        //Export selected annotations into XFDF format 

        document.ExportAnnotations(@"Annotation" + i + ".fdf", AnnotationDataFormat.Fdf, collection); 

        i++; 

    } 

} 

Please find the sample for the same from below link,
