Optional Content Layers

This example loads a PDF that contains several optional content layers. You can turn the display of individual layers on or off in the layers panel on the left.

window.onload = function(){ //DsPdfViewer.LicenseKey = "***key***"; const viewer = new DsPdfViewer("#viewer", { workerSrc: "/document-solutions/javascript-pdf-viewer/demos/product-bundles/build/dspdfviewer.worker.js", supportApi: getSupportApiSettings() }); viewer.toolbarLayout.viewer.default = ["open", "zoom", "save", "about"]; viewer.toolbarLayout.viewer.mobile = ["open", "zoom", "save", "about"]; const layersPanelHandle = viewer.addLayersPanel(); viewer.open("/document-solutions/javascript-pdf-viewer/demos/product-bundles/assets/pdf/house-plan.pdf").then(()=> { viewer.openPanel(layersPanelHandle); }); }
