Declaration
case downDiscussion
The (x,y) pixel coordinates of the origin point (0,0) represent the rightmost column and bottom row, respectively. Pixel (x,y) positions increase right-to-left, bottom-to-top.
If an image is encoded with this orientation, then displayed by software unaware of orientation metadata, the image appears rotated 180°.
