PDFJS Express - createSignHereElement

Technical Support

I am trying the “createSignHereElement” code snippet. I copied it on one of the index.js files, but I don’t see the “SignHere” element on my page. I am trying to recreate what they showed here https://pdfjs.express/documentation/signature/signature-field . Can someone help with this?

Code:
const createSignHereElement = Annotations.SignatureWidgetAnnotation.prototype.createSignHereElement;

Annotations.SignatureWidgetAnnotation.prototype.createSignHereElement = () => {
// signHereElement is the default one with dark blue background
const signHereElement = createSignHereElement.apply(this, arguments);

signHereElement.style.background = ‘red’;
return signHereElement;
}

Hi,

That API just changes the styling of the sign here elements that are created by the viewer. This does not add a sign here element to the PDF. For that API to do anything, the document has to have a sign here element already in it.

Express does not support form creation. If you need this functionality, check out our sister product, PDFTron WebViewer.

Thanks!
Logan
