Struct PatternImage 

pub struct PatternImage {
    pub width: u32,
    pub height: u32,
    pub data: Vec<u8>,
}

An RGBA8 pattern image used for fill-pattern and line-pattern rendering.

The image is stored as a flat Vec<u8> in row-major RGBA order (width × height × 4 bytes). Typically shared via Arc<PatternImage> so the same image can be referenced by the style, the engine mesh data, and the renderer without cloning pixel data.

Fields

width: u32

Image width in pixels.

height: u32

Image height in pixels.

data: Vec<u8>

Pixel data in RGBA8 format (width * height * 4 bytes).

Implementations

impl PatternImage

pub fn new(width: u32, height: u32, data: Vec<u8>) -> Self

Create a new pattern image from raw RGBA8 pixel data.

Panics

Panics if data.len() != width * height * 4.

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

Performs copy-assignment from source.

impl Debug for PatternImage

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