Rotate180 = 3

Rotated 180° (EXIF 3).

FlipV = 4

Mirrored vertically (EXIF 4).

Transpose = 5

Mirrored along the top-left/bottom-right diagonal (EXIF 5).

Rotate90 = 6

Rotate 90° clockwise to display (EXIF 6).

Transverse = 7

Mirrored along the top-right/bottom-left diagonal (EXIF 7).

Rotate270 = 8

Rotate 270° clockwise (90° anticlockwise) to display (EXIF 8).

Implementations

impl Orientation

pub fn from_exif(v: u32) -> Orientation

From an EXIF Orientation value; unknown values map to Orientation::Normal.

pub fn from_exif_checked(v: u32) -> Option<Orientation>

From an EXIF Orientation value; None for values outside 1-8.

pub fn exif(self) -> u32

The EXIF Orientation value (1-8).

pub fn swaps_dimensions(self) -> bool

True if width and height swap when applied.
