Image

The Image widget displays an image. The source of the image is specified as a URL using the source property. By default, specifying the width and height of the item causes the image to be scaled to that size. This behavior can be changed by setting the fill_mode property, allowing the image to be stretched or scaled instead. The property alignment controls where to align the scaled image.
