![]() These images are downloaded by an internal HTTP request, and then decoded. You can also use image source files that aren't part of the app, for example images from external servers. For more info on app resources and how to package image source files in an app package, see Defining app resources. For large files, there might be a very small delay while the image source file is decoded, if this is the first time the source is used. You typically use image source files that you have included as part of your app download package. If you want to verify that an image source file was loaded correctly, you can handle the ImageOpened event on the Image element. An error in decoding can also fire ImageFailed. You can write an ImageFailed handler and attach it to the Image object, and possibly use the ErrorMessage in event data to determine the nature of the failure. Setting the source to a Uniform Resource Identifier (URI) value that can't be resolved to a valid image source file doesn't throw an exception. The framework will wait for the image source to be returned, and will start a layout cycle when the image source file is available and decoded. Because it's a property, there isn't an awaitable syntax, but for most scenarios you don't need to interact with the asynchronous aspects of image loading. Setting the Source property is inherently an asynchronous action. In this example, the image source file is in an Images subfolder within the app's file structure. This is usually the same location that the XAML file containing the Image tag is loaded from. The root of this Uniform Resource Identifier (URI) is the base folder for an app project. Note that the Uniform Resource Identifier (URI) here appears to be a relative Uniform Resource Identifier (URI) supporting partial Uniform Resource Identifier (URI) is another XAML shortcut. This usage is setting Source by Uniform Resource Identifier (URI), which is a shortcut that's enabled by XAML. Here's a simple example of setting Source in XAML: To set the image source file that an Image displays, you set its Source property, either in XAML or in code. When your app is compiled for or runs on previous versions, the SVG image will not be shown. Scalable Vector Graphics (SVG) support is available when your app is compiled for Windows 10, version 1703 and running on version 1703 (or later).

The image source can also be set with a stream. The image source is specified by referring to an image file, using several supported formats. Represents a control that displays an image.
