Open the Graphic Signature tool using a link annotation

A PDF link annotation can execute arbitrary JavaScript code. This sample loads a PDF containing a link annotation with JavaScript code which, when clicked in DsPdfViewer, calls a DsPdfViewer-specific method showSignTool() that opens the Graphic Signature tool.

window.onload = function(){ const viewer = new DsPdfViewer("#viewer", { workerSrc: "/document-solutions/javascript-pdf-viewer/demos/product-bundles/build/dspdfviewer.worker.js", supportApi: getSupportApiSettings(), restoreViewStateOnLoad: false }); viewer.addDefaultPanels(); viewer.addAnnotationEditorPanel(); viewer.open("/document-solutions/javascript-pdf-viewer/demos/product-bundles/assets/pdf/viewer-link-execute-custom-js-action.pdf"); }
