same image.

the container dimensions. This may crop the top and bottom of the
image if the scaled image height is greater than the container
height, or crop the left and right of the image if the scaled image
width is greater than the container width. This is similar to "Zoom
Mode" on a widescreen TV when playing a 4:3 video.

bars.
Unspecified

bars.
