Struct CropRegion 

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

An explicit crop region applied before resize.

Crop extracts a rectangular sub-image at the given pixel coordinates. The origin (x, y) is the top-left corner and (width, height) define the size of the extracted region. Both dimensions must be non-zero.

Examples

use truss::CropRegion;
use std::str::FromStr;

let region = CropRegion::from_str("10,20,100,200").unwrap();
assert_eq!(region.x, 10);
assert_eq!(region.y, 20);
assert_eq!(region.width, 100);
assert_eq!(region.height, 200);
assert_eq!(format!("{region}"), "10,20,100,200");

// Zero-size regions are rejected
assert!(CropRegion::from_str("0,0,0,100").is_err());

Fields

x: u32

Horizontal offset from the left edge.

y: u32

Vertical offset from the top edge.

width: u32

Width of the crop region.

height: u32

Height of the crop region.
