Optional Content Layers

Theme:

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);
	});	
}

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);
});	
}
