How can I set the drag gesture within the bounds of a selected image

Question

I am doing some tests where someone can select an image from their photo gallery . Once they select an image there will be a text in the center of the image "Sample test" I want that text to be draggable within the bounds of the image selected . I have everything working except getting the correct bounds of the image . I am able to drag that test outside of the image frame . I am getting the frame of the image in the PhotosPicker . Does anyone know how I can get the correct frame of image selected
