Struct ImageRegion 

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

Describes a 2D region for image-like buffer copies.

Fields

x: u32

X offset in pixels.

y: u32

Y offset in pixels.

width: u32

Width in pixels.

height: u32

Height in pixels.

Implementations

impl ImageRegion

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

Create a new image region.

pub fn from_size(width: u32, height: u32) -> Self

Create a region starting at the origin.

pub fn pixel_count(&self) -> u64

Total pixel count.

pub fn contains_point(&self, px: u32, py: u32) -> bool

Check if a point is inside the region.

Trait Implementations

impl Clone for ImageRegion

fn clone(&self) -> ImageRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ImageRegion

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

Formats the value using the given formatter.

impl PartialEq for ImageRegion

fn eq(&self, other: &ImageRegion) -> 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.
