Struct imageproc::rect::Rect

pub struct Rect { /* fields omitted */ }

A rectangular region of non-zero width and height.

Examples

use imageproc::rect::Rect;
use imageproc::rect::Region;

// Construct a rectangle with top-left corner at (4, 5), width 6 and height 7.
let rect = Rect::at(4, 5).of_size(6, 7);

// Contains top-left point:
assert_eq!(rect.left(), 4);
assert_eq!(rect.top(), 5);
assert!(rect.contains(rect.left(), rect.top()));

// Contains bottom-right point, at (left + width - 1, top + height - 1):
assert_eq!(rect.right(), 9);
assert_eq!(rect.bottom(), 11);
assert!(rect.contains(rect.right(), rect.bottom()));

Methods

impl Rect

fn at(x: i32, y: i32) -> RectPosition

Reduces possibility of confusing coordinates and dimensions when specifying rects.

fn top(&self) -> i32

Smallest y-coordinate reached by rect.

fn left(&self) -> i32

Smallest x-coordinate reached by rect.

fn bottom(&self) -> i32

Greatest y-coordinate reached by rect.

fn right(&self) -> i32

Greatest x-coordinate reached by rect.

fn width(&self) -> u32

Width of rect.

fn height(&self) -> u32

Height of rect.

fn intersect(&self, other: Rect) -> Option<Rect>

Returns the intersection of self and other, or none if they are are disjoint.

Trait Implementations

impl Copy for Rect

impl Clone for Rect

fn clone(&self) -> Rect

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Rect

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl PartialEq for Rect

fn eq(&self, __arg_0: &Rect) -> bool

This method tests for self and other values to be equal, and is used by ==.

This method tests for !=.

impl Eq for Rect

impl Region<i32> for Rect

fn contains(&self, x: i32, y: i32) -> bool
