Struct AtlasRect 

pub struct AtlasRect {
    pub u_min: f32,
    pub v_min: f32,
    pub u_max: f32,
    pub v_max: f32,
}

纹理图集中的矩形区域

UV 坐标范围 [0, 1]，表示图集纹理中的子区域。

示例

use anvilkit_render::renderer::sprite::AtlasRect;

let rect = AtlasRect::new(0.0, 0.0, 0.25, 0.25); // 左上角 1/4 区域
assert_eq!(rect.width(), 0.25);
assert_eq!(rect.height(), 0.25);

Fields

u_min: f32

左上角 U

v_min: f32

左上角 V

u_max: f32

右下角 U

v_max: f32

右下角 V

Implementations

impl AtlasRect

pub fn new(u_min: f32, v_min: f32, u_max: f32, v_max: f32) -> Self

pub fn full() -> Self

全纹理区域

pub fn width(&self) -> f32

pub fn height(&self) -> f32

Trait Implementations

impl Clone for AtlasRect

fn clone(&self) -> AtlasRect

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AtlasRect

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

Formats the value using the given formatter.

impl Default for AtlasRect

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for AtlasRect

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

impl Copy for AtlasRect

impl StructuralPartialEq for AtlasRect
