Issue while Importing annotations in Web-Viewer by using XFDF string

laxmidurga.subhadrad · October 13, 2023, 12:33pm

HI,
I want to import Annoations in same document at synchronization time in Multiple screens
Here are the steps to reproduce the issue

I have imported some Annotations Manually in document.(screen 1), Here is the XFDF string for that

 <annots>
 	<square page="0" rect="65.670,704.010,321.980,758.850" color="#E44234" flags="print" name="e9182352-4d28-d247-7ac8-e1c8571ed10c" title="Romit Dasgupta" subject="Rectangle" date="D:20231013172708+05'30'" creationdate="D:20231013172706+05'30'"/>
 	<highlight page="0" rect="72.030,686.358,242.640,697.918" color="#00CC63" flags="print" name="ae9f245b-5245-2c25-6afa-6751cfb4b17f" title="Romit Dasgupta" subject="Highlight" date="D:20231013174815+05'30'" creationdate="D:20231013174815+05'30'" coords="72.03,697.918,242.64000000000007,697.918,72.03,686.3580000000001,242.64000000000007,686.3580000000001">
 		<trn-custom-data bytes="{&quot;trn-annot-preview&quot;:&quot;This is a small demonstration .pdf file -&quot;}"/>
 	</highlight>
 </annots>

Then I am deleting Highlight Annotation from Screen 1, Screen 1 looks like below

 <annots>
 	<square page="0" rect="65.670,704.010,321.980,758.850" color="#E44234" flags="print" name="e9182352-4d28-d247-7ac8-e1c8571ed10c" title="Romit Dasgupta" subject="Rectangle" date="D:20231013172708+05'30'" creationdate="D:20231013172706+05'30'"/>
 </annots>

But in the Screen 2, Even though XFDF string got updated, Deleted Annnotations are still present in Web viewer.
If we refresh the page then it is updating Annotations in UI . But Without refresh the page I want to update the Annotations in UI in Screen 2 as well

Here is the XFDF string for that

	<annots>
		<square page="0" rect="65.670,704.010,321.980,758.850" color="#E44234" flags="print" name="e9182352-4d28-d247-7ac8-e1c8571ed10c" title="Romit Dasgupta" subject="Rectangle" date="D:20231013172708+05'30'" creationdate="D:20231013172706+05'30'"/>
	</annots>

Hello laxmidurga.subhadrad,

We will take a look at the issue presented, but we require more info. Can you please provide the following:

Can you please tell us which version of WebViewer are you using?
Can you provide us with the exact steps you are a using to reproduce the issue?
Have you tried using one of the following APIs to redraw the annotations (or page):
Apryse WebViewer Class: DocumentViewer or Apryse WebViewer Class: AnnotationManager

Also, you have already made a thread about this issue here: How to refresh the UI in pdfwebviewer by using pdftron inbuilt methods?
But haven’t provided the required info. I think these two tickets might be merged, just a little heads-up.
