Is there any possibility to not load all current annotatnions while loading PDF?
I assume that all links in PDF document are treated like annotatnions, so for larger files it takes a few minutes to generate document content. So I want to know how I can disable loading all existing annotatnions when document content is loaded.
Please provide a link to a minimal sample where the issue is reproducible:
Hi,
You can try set the “enableAnnotations” option to be false when initializing WebViewer, please see PDFTron WebViewer Global
Thanks.

So I need to use this as an option when initialize WebViewer, and then am I able to enable Annotatnion again using viewerLoaded event?
Best Regards,
Also I can see that this option isn’t working.
Maybe I use it incorrect.
Here is how i use it:
WebViewer(
{
path: "http://localhost:@BridgeSettings.WebPort/lib/PDFViewer/lib",
initialDoc: "http://localhost:@BridgeSettings.WebPort/Signing/GetPDF",
licenseKey: "",
css: "http://localhost:@BridgeSettings.WebPort/lib/PDFViewer/lib/ui/buttons.css",
enableAnnotations: false
},
viewerElement
I’m also using annotationChanged event like here:
annotationManager.addEventListener('annotationChanged',
(annotations, action) => {
if (action === 'add') {
// My code here
console.log("create");
}
else if (action === 'modify') {
console.log('this change modified annotations');
}
else if (action === 'delete') {
console.log("delete");
// My code here
}
annotations.forEach((annot) => {
console.log(`Page Number: ${annot.PageNumber} X: ${annot.getX ()} Y: ${annot.getY ()}`);
console.log(`width: ${annot.getWidth ()} Height: ${annot.getHeight ()}`);
console.log(docViewer.getPageHeight(annot.PageNumber));
// My code here
});
});
And after setting enableAnnotatnions to false I still get info about loaded annotatnions like here:
How can I fix it?
If you see annotations not loaded in the document and annotation tools are hidden, then it means that the option is working properly.
It is as you wrote.
I cannot use annotatnion tool, but links are still threated as annotations and are loaded when document is loading.
How can I turn that off? Every link is like annotation, so for bigger documents it takes a lot of time to load the document. I want to avoid that, and make the load time as short as possible.
Hi,
Another way is to use this code but pass the empty string into the callback function https://www.pdftron.com/documentation/web/guides/annotation/import-export/advanced-load/
Could you give it a try?
Thanks.

I tried it.
Here is my code, and error which i get.
Code:
docViewer.setPagesUpdatedInternalAnnotationsTransform((xfdfData, callback) => {
callback("");
});
Error:
Please follow the first example, which uses “(xfdfData, pageList, callback)”.
I copied the whole example, still the same error message.
Could you attach your code here? Thanks.
Hi!
Here is my code.
WebViewer(

path: "http://localhost:@BridgeSettings.WebPort/lib/PDFViewer/lib",
initialDoc: "http://localhost:@BridgeSettings.WebPort/Signing/GetPDF",
licenseKey: "license_key",

//enableAnnotations: false
},
viewerElement
).then((instance) => {
instance.closeElements('rubberStampOverlay');
instance.UI.disableElement('customStampPanelButton');
/*
* My code (not important in this case)
*/
docViewer.setPagesUpdatedInternalAnnotationsTransform((xfdfData, callback) => {
const parser = new DOMParser ();
const xfdfElements = parser.parseFromString(xfdfData, 'text/xml');
[].forEach.call(xfdfElements.querySelectorAll('link'),
e => {
e.parentNode.removeChild(e);
});
const serializer = new XMLSerializer ();
callback(serializer.serializeToString(xfdfElements));
});
/*
* My code (not important in this case)

const myStamp = 'http://localhost:@BridgeSettings.WebPort/sample.svg';
// instance.docViewer.getTool(instance.Tools.ToolNames.RUBBER_STAMP).setStandardStamps([myStamp]);
const myStamp1 = 'http://localhost:@BridgeSettings.WebPort/sample1.svg';
instance.docViewer.getTool(instance.Tools.ToolNames.RUBBER_STAMP).setStandardStamps([myStamp, myStamp1]);

docViewer.on('annotationsLoaded',
() => {
console.log("LOADED!!!!");

});
annotationManager.addEventListener('annotationChanged',

console.log(annot);
});
});

Hi,
Looks like in your code, you still have two parameters here instead of the (xfdfData, pageList, callback) which is in the first example in https://www.pdftron.com/documentation/web/guides/annotation/import-export/advanced-load/
