Struct Padding2D 

pub struct Padding2D {
    pub top: usize,
    pub bottom: usize,
    pub left: usize,
    pub right: usize,
}

Represents 2D padding with top, bottom, left, and right values (in pixels).

Fields

top: usize

Amount of padding to add on the top side.

bottom: usize

Amount of padding to add on the bottom side.

left: usize

Amount of padding to add on the left side.

right: usize

Amount of padding to add on the right side.

Implementations

impl Padding2D

pub fn validate_size(&self, old_size: ImageSize, new_size: ImageSize) -> bool

Validates that a new image size correctly matches the expected dimensions after applying this padding to an existing image.

Arguments

• old_size: The original image size before padding.
• new_size: The resulting image size after padding.

Returns

• true if the new_size width and height are equal to old_size.width + left + right and old_size.height + top + bottom, respectively.
• false otherwise.

Example

use kornia_image::ImageSize;
use kornia_imgproc::padding::Padding2D;
let padding = Padding2D { top: 1, bottom: 1, left: 2, right: 2 };
let old_size = ImageSize { width: 4, height: 4 };
let new_size = ImageSize { width: 8, height: 6 };

assert!(padding.validate_size(old_size, new_size));
