The value is an
NSNumber containing a
BOOL, which affects the interpretation of Proportional scaling types. A
NO value will make the image fully visible, but there may be empty space on the sides or top and bottom. A
YES value will cause the image to fill the entire screen, but the image may be clipped. If this is not specified,
NO is assumed. Non-proportional scaling types ignore this value.
