Enum imagepipe::Orientation

pub enum Orientation {
    Normal,
    HorizontalFlip,
    Rotate180,
    VerticalFlip,
    Transpose,
    Rotate90,
    Transverse,
    Rotate270,
    Unknown,
}

Possible orientations of an image

Values are taken from the IFD tag Orientation (0x0112) in most cases but they can be obtained from other metadata in the file.

Methods

impl Orientation

pub fn from_u16(orientation: u16) -> Orientation

Convert a u16 from the IFD tag Orientation (0x0112) into its corresponding enum value

pub fn to_flips(&self) -> (bool, bool, bool)

Convert orientation to an image flip operation tuple. The first field is if x and y coordinates should be swapped (transposed). The second and third field is horizontal and vertical flipping respectively. For a correct result, flipping must be done before transposing.
