Struct RoiRegion 

pub struct RoiRegion {
    pub x: i32,
    pub y: i32,
    pub width: u32,
    pub height: u32,
    pub priority: f64,
    pub label: String,
}

A rectangular region of interest within a frame.

Fields

x: i32

Left edge in pixels.

y: i32

Top edge in pixels.

width: u32

Width in pixels.

height: u32

Height in pixels.

priority: f64

Priority weight (0.0 = ignore, 1.0 = normal, >1.0 = boosted).

label: String

Optional label for the region.

Implementations

impl RoiRegion

pub fn new(x: i32, y: i32, width: u32, height: u32) -> Self

Creates a new ROI region with default priority.

pub fn with_priority( x: i32, y: i32, width: u32, height: u32, priority: f64, ) -> Self

Creates a new ROI region with a given priority weight.

pub fn set_label(&mut self, label: &str)

Sets the label for this region.

pub fn area(&self) -> u64

Returns the area of the region in pixels.

pub fn right(&self) -> i32

Returns the right edge coordinate.

pub fn bottom(&self) -> i32

Returns the bottom edge coordinate.

pub fn contains(&self, px: i32, py: i32) -> bool

Checks whether a pixel coordinate falls inside this region.

pub fn overlaps(&self, other: &Self) -> bool

Checks whether two regions overlap.

pub fn intersection_area(&self, other: &Self) -> u64

Returns the intersection area with another region, or 0 if they don’t overlap.

Trait Implementations

impl Clone for RoiRegion

fn clone(&self) -> RoiRegion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RoiRegion

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

Formats the value using the given formatter.

impl PartialEq for RoiRegion

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