blit
A Rust library for blitting 2D sprites
Documentation
Usage
Add this to your Cargo.toml:
[dependencies]
blit = "0.5"
And this to your crate root:
extern crate blit;
Run the example
On Linux you need the xorg-dev package as required by minifb. sudo apt install xorg-dev
cargo run --example smiley
This should produce the following window:
Examples
extern crate image;
use blit::*;
const WIDTH: usize = 180;
const HEIGHT: usize = 180;
const MASK_COLOR: u32 = 0xFF00FF;
let mut buffer: Vec<u32> = vec![0xFFFFFFFF; WIDTH * HEIGHT];
let img = image::open("examples/smiley.png").unwrap();
let img_rgb = img.as_rgb8().unwrap();
// Blit directly to the buffer
let pos = (0, 0);
img_rgb.blit(&mut buffer, WIDTH, pos, Color::from_u32(MASK_COLOR));
// Blit by creating a special blitting buffer first, this has some initial
// overhead but is a lot faster after multiple calls
let blit_buffer = img_rgb.to_blit_buffer(Color::from_u32(MASK_COLOR));
let pos = (10, 10);
blit_buffer.blit(&mut buffer, WIDTH, pos);
let pos = (20, 20);
blit_buffer.blit(&mut buffer, WIDTH, pos);
// Save the blit buffer to a file
blit_buffer.save("smiley.blit");
