The size of the image often does not fit the size of the component. In such cases, you can find empty space inside the component. The image size may be larger than the component size. In this situation the image needs to be stretched to fill it inside the component. To do this, the Image component's Stretch property must be true.
After setting the Stretch property to true the image will fill all free space of the component. Stretching an image can destroy its proportions. To stretch the image and maintain its proportions, the AspectRatio property must be set to true. Also, the Image component always maintains the proportions of the image.
caution: AspectRatio property is only processed when image stretching is enabled
