ufb

Just quickly show or draw a framebuffer in a window, nothing else!

Why use ufb: - Uses hardware-acceleration via OpenGL. - To quickly debug image or framebuffer output, instead of writing to files. - Supports L8, La8, Rgb8 and Rgba8 &[u8] buffers. - Fast to build. - Doesn't need vulkan drivers. - Minimal interface.

Usage

toml [dependencies] ufb = "*"

```rust use ufb::{ColorDepth, Window};

const WIDTH: u32 = 768; const HEIGHT: u32 = 768;

fn main() { let mut fb: Vec = vec![0u8; (WIDTH * HEIGHT * 3) as usize]; for (iter, pixel) in fb.chunksexactmut(3).enumerate() { let x = iter % WIDTH as usize; let y = iter / WIDTH as usize; let val = x ^ y; let hex = format!("{:06x}", val); let r = u8::fromstrradix(&hex[0..2], 16).unwrap(); let g = u8::fromstrradix(&hex[2..4], 16).unwrap(); let b = u8::fromstrradix(&hex[4..6], 16).unwrap(); pixel.copyfromslice(&[r, g, b]); }

let mut win = Window::new(WIDTH, HEIGHT, "Hello").unwrap();
win.show(&fb, ColorDepth::Rgb8).unwrap();

} ```

Using the image crate: ```rust use ufb::{ColorDepth, Window}; use image::GenericImageView;

fn main() { let img = image::open("screenshots/image.jpg").unwrap(); let (w, h) = img.dimensions();

let mut win = Window::new(w, h, "Hello").unwrap();
win.show(&img.to_rgba8(), ColorDepth::Rgba8).unwrap();

} ```
