Struct ClapBox 

#[non_exhaustive]
pub struct ClapBox {
    pub width_n: u32,
    pub width_d: u32,
    pub height_n: u32,
    pub height_d: u32,
    pub horiz_off_n: i32,
    pub horiz_off_d: u32,
    pub vert_off_n: i32,
    pub vert_off_d: u32,
}

Clean Aperture box (clap).

Defines a crop rectangle as centered rational values. 32 bytes payload: 4 pairs of (numerator u32, denominator u32), except offsets which are signed numerators.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

width_n: u32

width_d: u32

height_n: u32

height_d: u32

horiz_off_n: i32

horiz_off_d: u32

vert_off_n: i32

vert_off_d: u32

Implementations

impl ClapBox

pub fn new( width_n: u32, width_d: u32, height_n: u32, height_d: u32, horiz_off_n: i32, horiz_off_d: u32, vert_off_n: i32, vert_off_d: u32, ) -> Self

Create from width, height, and center offset as rational numbers (n/d pairs).

Trait Implementations

impl Clone for ClapBox

fn clone(&self) -> ClapBox

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ClapBox

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ClapBox

fn eq(&self, other: &ClapBox) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
