Arrow annotations

Hi,
My question is about Arrow annotations and PdfDocumentView. There is no PdfDocumentView.PdfViewerAnnotationMode.Arrow so could you please let me know how to add an arrow annotation? Thought it would work similar to using PDFViewer.AnnotationMode = PdfDocumentView.PdfViewerAnnotationMode.Line, isn't it?
Thanks in advance,
Martin

Hi Martin, 

Since “Arrow” annotation is a subtype of the “Line” annotation, we do not have any specific API mode for the “Arrow” annotation. You can draw an arrow annotation by specifying the AnnotationMode as Line and by setting the begin or end line style using the ArrowAnnotationSettings as mentioned in the following documentation. 
However, we are unable to draw an arrow annotation as expected using `PdfDocumentView`. We are currently validating this and will provide you further details on 19th June 2020. 

Regards,

Hi Martin, 

We have analyzed further on enabling the arrow annotation from code behind using PdfDocumentView and we do not have any APIs implemented to enable and draw arrow annotation from code. In future, we have plans to customize the start and end line style for the Line annotations, it will help you to draw arrow annotation in the PDF document from code behind. We have logged feature request for the same and the implementation of this feature can be tracked through the following feedback portal. 

As of now, we recommend you use `PdfViewerControl` to add arrow annotations in the PDF document using our built-in toolbar. You can find the PdfViewerControl sample project from the following GitHub location: https://github.com/syncfusion/wpf-demos/tree/master/PDF%20Viewer/Shapes/Shapes

Hi Deepak,
Many thanks for your feedback. In my case PdfDocumentView is used in a WPF user control and the complete PdfViewerControl would be some kind of 'overkill' as I just have to use PDF viewing, rotation and annotations - nothing else. I am looking forward when your solution for creating arrow annotations via code behind is available.
kind regards,
Martin

Hi Martin, 
 
Thanks for your update.  
 
At present, we do not have any immediate plans to implement the support to “Customize the start and end style of the line annotation”. At the planning stage for every release cycle, we review all open features and identify features for implementation based on specific parameters including product vision, technological feasibility, and customer interest.      
 
Based on our present commitments and the above parameters, this feature is expected to be implemented in our 2021 Volume 1 main release. We will let you know when this feature is implemented.    You can now track the status of this feature request here,         

 
Disclaimer: The date for the feature implementation is tentative and not a commitment on our parts.      
   
Regards, 
Uthandaraja S

Hi Martin, 
 
We have enabled drawing Arrow shapes using the AnnotationCommand and to customize it’s start and end styles programmatically. Included this in Essential Studio 2021 Volume 2 release v19.2.0.44 and you can download it under the following link.  
 
 
Please find the below documentation details for more details. 
 
 
 
 
We thank you for your support and appreciate your patience in waiting. Please get in touch with us if you would require any further assistance. 
 
Regards, 
Vikas
