Struct PixelBuffer 

pub struct PixelBuffer {
    pub width: u32,
    pub height: u32,
    pub pixels: Vec<u8>,
}

An RGBA pixel buffer.

Fields

width: u32

height: u32

pixels: Vec<u8>

Row-major RGBA bytes [r, g, b, a, r, g, b, a, …]

Implementations

impl PixelBuffer

pub fn new(width: u32, height: u32) -> Self

Create a new zeroed pixel buffer.

pub fn set_pixel(&mut self, x: u32, y: u32, r: u8, g: u8, b: u8, a: u8)

Set pixel at (x, y) to RGBA.

pub fn get_pixel(&self, x: u32, y: u32) -> [u8; 4]

Get pixel at (x, y).

pub fn fill(&mut self, r: u8, g: u8, b: u8, a: u8)

Fill entire buffer with a flat color.

pub fn byte_len(&self) -> usize

Byte count.

pub fn to_tga_bytes(&self) -> Vec<u8>

Export as a TGA file (simple uncompressed 32-bit RGBA TGA — no external crates needed).

TGA format: 18-byte header + pixel data (top-to-bottom with flip flag).

pub fn save_tga(&self, path: &Path) -> Result<()>

Save to a .tga file.
