Live edits to PDF

[claude hasler]

Hello, 

A quick look has shown me that Syncfusion offers two functions concerning PDFs: 

1)Non-UI Editing/Creation

2) a PDF Viewer. 

Is it possbile to combine the two, and display a PDF, programatically apply a change, and see that change appear live in the viewer? 

More specifically, i would like to be able to draw "freeform" shapes into the PDF (With line segments? https://help.syncfusion.com/flutter/pdf/working-with-shapes). Additionally, to be able to draw inside the PDF the PDF viewer itself must offer some sort of callback providing touch events with Document-Coordinates, does something like this exist?

Is such functionality possible using the Syncfusion libraries?

Edit: just found this https://www.syncfusion.com/feedback/26333/support-for-ink-annotations, are there any updates to this feature?

Regards

Hi Claude,

 

A quick look has shown me that Syncfusion offers two functions concerning PDFs:  1)Non-UI Editing/Creation 2) a PDF Viewer.    Is it possbile to combine the two, and display a PDF, programatically apply a change, and see that change appear live in the viewer?	At present, the Syncfusion Flutter PDF Viewer does not support editing PDF documents directly. However, you can use the syncfusion_flutter_pdf library to edit the document and then reload the updated PDF in the viewer. Please refer to the attached sample, which demonstrates how to add a new page to the end of the document, save it, and reload it in the PDF viewer.
Additionally, to be able to draw inside the PDF the PDF viewer itself must offer some sort of callback providing touch events with Document-Coordinates, does something like this exist?	Syncfusion Flutter PDF viewer supports `onTap` callback which allows to retrieve the document coordinates of the tap location. Please refer to the UG for more details: Gesture callbacks in Flutter PDF Viewer widget | Syncfusion

At present, Syncfusion Flutter PDF Viewer does not have the support for free form drawing (ink) annotations. While we do not have immediate plans to implement this feature, it is currently under active review. Once, we decide on the implementation, we will keep you posted through the feedback portal link. You can follow the feedback link for any further updates.   Support for ink annotations in Flutter | Feedback Portal
