Annotations cannot function properly when open a Optimized(linearized) PDF

[Jessie Lin]

Hi, 

I have a problem to open a optimized PDF on WebViewer with given annotations(XFDF).  'Accept-Rage: bytes' is added in the response header and the file type is PDF. The given annotation is not able to be modified or display on WebViewer. I have this problem since version 2.2.0. I tried with version 2.2.1 but the problem is still there even though the behavior and sympthon are slightly different . 

version 2.2.0: The serverUrl is triggered and the annotations appear. However when the Note Panel is trogged. then annotations disapper. 

version 2.2.1: The serverUrl is NOT triggered and the annotations from XFDF do not appear. 

In version 2.2.0 , if I setup a breakpoint at server to slow the response for XFDF, then the annotation will appear and function normal after PDF is loaded. According to this, I think it seems to be the AJAX call get XFDF too quick before the PDF is fully loaded. However, there is no option to configure when or how the XFDF to be loaded. 

I would like to know what I can do to solve this problem. Thank you.

Best regards,

Jessie

Hi Jessie,

For now you'll have to set the option useDownloader: false in the PDFTron.WebViewer constructor. We're currently working on having this behave properly when useDownloader is set to true.

HI Matt, 

After setting useDownloader to false it's working. Thank you.
