This method will load the data from url and add a new ImageViewerItem. This is done through the use of ImageLoader, meaning a ImageLoading event will be fired when the image loading is about to begin. When loading from AddFromSvgUrl or InsertFromSvgUrl, the image will load with AjaxXml, which only works for SVG Elements or XML/XHTML Elements. To intercept and change this loading style, attach a callback to the ImageLoading event. The HTML Image Element will be set to the Element property when finished. The image data is loaded in the background and ImageSize is updated as described in Url.
When loading from AddFromSvgUrl or InsertFromSvgUrl, the image will load with AjaxXml, which only works for SVG Elements or XML/XHTML Elements.
This method is a shortcut for the following:
var item = new lt.Controls.ImageViewerItem();
item.loadUrlMode = lt.ImageLoaderUrlMode.ajaxXml;
item.Url = url;
imageViewer.items.add(item);
If url is null, then an empty item is added.
// Attach to the loading-done event this._imageViewer.imageLoading.add(function (sender, e) => { e.imageLoader.done.add(function () { // Force pointer events everywhere except the background (so we can pan/zoom on the background) // Note: ElementInsertionHelper is not *guaranteed* to work with all SVG elements lt.Controls.ElementInsertionHelper.forcePointerEventsFromRoot(e.item.element); lt.Controls.ElementInsertionHelper.removePointerEvents([e.item.element]); }); }); // Add this SVG element as a true SVG, and use the callback above for it this._imageViewer.items.addFromUrl("http://demo.leadtools.com/images/svg/lazio.svg", lt.LeadSizeD.create(96, 96));
