Tracked Changes/Suggestions

[Amanda Iverson]

Hello!

I would like to import a pdf into the editor, and have a user track changes/make suggestions that we can capture externally as well as display on the final product within the editor. Is there a feature in this library that can assist with that?

Hi Amanda, 

Syncfusion Greetings! 

Currently, we don’t have any library for Pdf to Docx conversion to import pdf document in editor. 

 

Please let us know if you need any further assistance.

Ok, Thank you!

I do have another question to build off of that. I would like to be able to annotate a PDF text document with changes, is it possible for me to capture the page number and line number that the pdf document annotation occurred?

Hi Amanda, 

  

We can retrieve the annotation details using annotationCollection object.  

Please refer to the below code snippet: 

Code snippet: 

  

var pdfViewer = document.getElementById('pdfviewer').ej2_instances[0]; 

 

console.log(pdfViewer. annotationCollection); 

  

  

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/Sample_-_annotationDetails1864480271 

  

And can you please confirm whether you need the annotation details  while annotation are rendering on UI or while saving the document in server side. 

  

Kindly try it and revert us with more details if the provided solution is not meet your requirement.

Thank you for the reply.

I would like to capture the annotation details when saving on the server side if possible, but if i am only able to capture the line number and page number on the UI side, I can make that work.

Hi Amanda, 

 

Thanks for the update. 

We can retrieve the annotation bounds and page number on the server-side while saving or downloading the PDF document by using the below code-snippet, We have created the sample in which we have modified the PDFViewerController.cs file Download method. Kindly refer to the sample below. 

Sample: https://www.syncfusion.com/downloads/support/directtrac/general/ze/SAMPLE~1698660154 

Code Snippet: 

public IActionResult Download([FromBody] Dictionary<string, string> jsonObject) 

        { 

            PdfRenderer pdfviewer = new PdfRenderer(_cache); 

            string documentBase = pdfviewer.GetDocumentAsBase64(jsonObject); 

            string base64String = documentBase.Split(new string[] { "data:application/pdf;base64," }, StringSplitOptions.None)[1]; 

            if (base64String != null || base64String != string.Empty) 

            { 

                byte[] byteArray = Convert.FromBase64String(base64String); 

 

                MemoryStream docStream = new MemoryStream(byteArray); 

                PdfLoadedDocument loadedDocument = new PdfLoadedDocument(docStream); 

                for (int i=0;i< loadedDocument.Pages.Count;i++) 

                { 

                    PdfLoadedPage loadedPage = loadedDocument.Pages[i] as PdfLoadedPage; 

                    for (int j = 0; j < loadedPage.Annotations.Count; j++) 

                    { 

                        PdfLoadedTextMarkupAnnotation loadedMarkup = loadedPage.Annotations[j] as PdfLoadedTextMarkupAnnotation; 

                        if(loadedMarkup != null) 

                        { 

                            var annotationLocation = loadedMarkup.BoundsCollection; // bounds of the annotation 

                            int annotationPage = i;//page number 

                        } 

                    } 

                } 

            } 

                return Content(documentBase); 

        }
