Struct ImageInstance 

#[repr(C)]
pub struct ImageInstance {
    pub position: [f32; 2],
    pub size: [f32; 2],
    pub uv_min: [f32; 2],
    pub uv_max: [f32; 2],
    pub tint: [f32; 4],
    pub border_radius: f32,
    pub texture_index: u32,
    pub z_depth: f32,
    pub _padding: f32,
}

Instance data for image rendering.

Each instance represents one image quad to be drawn from a texture. Supports UV coordinates for sprite sheets and tinting.

Fields

position: [f32; 2]

Position in screen space (top-left corner)

size: [f32; 2]

Size of the image quad in screen space

uv_min: [f32; 2]

UV coordinates (top-left)

uv_max: [f32; 2]

UV coordinates (bottom-right)

tint: [f32; 4]

Tint color (RGBA) - multiplied with texture color

border_radius: f32

Border radius for rounded corners (0 = sharp corners)

texture_index: u32

Texture index (for texture arrays, 0 for single texture)

z_depth: f32

Depth value for z-ordering (0.0 = far, 1.0 = near)

_padding: f32

Padding to align to 16-byte boundary

Implementations

impl ImageInstance

pub fn new(position: Vec2, size: Vec2, z_depth: f32) -> Self
