Struct PixelRect 

pub struct PixelRect {
    pub x: u32,
    pub y: u32,
    pub width: u32,
    pub height: u32,
}

An integer rectangle in source pixels, half-open: x..x + width by y..y + height. Arithmetic on its edges is done in u64, so no combination of fields overflows.

Fields

x: u32

y: u32

width: u32

height: u32

Implementations

impl PixelRect

pub const fn new(x: u32, y: u32, width: u32, height: u32) -> PixelRect

pub const fn full(width: u32, height: u32) -> PixelRect

The whole of a width × height frame.

pub const fn is_empty(&self) -> bool

Whether it covers no pixel.

pub const fn area(&self) -> u64

The number of pixels it covers.

pub const fn fits_in(&self, width: u32, height: u32) -> bool

Whether it lies inside a width × height frame. An empty rect fits wherever its origin does.

pub fn union(&self, other: &PixelRect) -> PixelRect

The smallest rect holding both. An empty operand contributes nothing.

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

The pixels both cover, or None when they share none.
