This sample shows how to hide the graphical signature tool from toolbar once the signature has been added.

window.onload = function(){ //DsPdfViewer.LicenseKey = "***key***"; let viewer; function applyNormalViewerLayout() { viewer.toolbarLayout.viewer = { default: ['save', 'edit-sign-tool', 'doc-title', '$split', 'about'], mobile: ['save', 'edit-sign-tool', 'doc-title', '$split', 'about'], fullscreen: ['$fullscreen', 'save', 'edit-sign-tool', 'doc-title', '$split', 'about'] }; viewer.applyToolbarLayout(); } function applySignedViewerLayout() { viewer.toolbarLayout.viewer = { default: ['save', 'doc-title', '$split', 'about'], mobile: ['save', 'doc-title', '$split', 'about'], fullscreen: ['$fullscreen', 'save', 'doc-title', '$split', 'about'] }; viewer.applyToolbarLayout(); } function onSignatureAdded(resultDetails) { viewer.scrollAnnotationIntoView(resultDetails.pageIndex, resultDetails.annotation); applySignedViewerLayout(); } var options = { workerSrc: "/document-solutions/javascript-pdf-viewer/demos/product-bundles/build/dspdfviewer.worker.js", supportApi: { apiUrl: window.top.SUPPORTAPI_URL, token: window.top.SUPPORTAPI_TOKEN, webSocketUrl: false }, restoreViewStateOnLoad: false }; options.signTool = { selectedTab: 'Draw', saveSignature: false, penColor: '#000000', penWidth: 2, hideSaveSignature: true, canvasSize: { width: 480, height: 168 }, autoResizeCanvas: false, destinationScale: 0.33, afterAdd: function (result) { onSignatureAdded(result); return true; }, location: { x: 87, y: 116 }, title: 'Landlord/Lessor', }; options.restoreViewStateOnLoad = false; viewer = new DsPdfViewer("#viewer", options); viewer.mouseMode = 1; viewer.addDefaultPanels(); viewer.addAnnotationEditorPanel(); viewer.zoom = 70; applyNormalViewerLayout(); viewer.open("/document-solutions/javascript-pdf-viewer/demos/product-bundles/assets/pdf/viewer-add-signature-from-toolbar.pdf"); }
