(Made with omage)
omage
is a Rust library for image processing. It provides functionality for handling images, drawing basic shapes, and configuring image properties.
Features
- Image configuration with background colors.
- Drawing circles and rectangles on the image.
- Drawing fonts on the image
- Saving the resulting image to a file.
Getting Started
To use omage
in your Rust project, add the following to your Cargo.toml
file:
[dependencies]
omage = "0.3.11"
Then, include it in your Rust code:
use omage::colors::*;
use omage::{Components, Config, Image};
const HEIGHT: u32 = 1080;
const WIDTH: u32 = 1920;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let config = Config::new(WIDTH, HEIGHT, WHITE, Some(BLACK), "output.png", None);
let mut image = Image::new();
let circle1 = Components::Circle(config.width / 2, config.height / 2, 300, RED);
let circle2 = Components::Circle(config.width / 2, config.height / 2, 305, BLACK);
image
.config(config)
.init()?
.add_components(vec![&circle1, &circle2])
.draw()?;
Ok(())
}
Output:
Examples
Drawing Circle
use omage::colors::*;
use omage::{Components, Config, Image};
const HEIGHT: u32 = 1080;
const WIDTH: u32 = 1920;
fn main() -> Result<(), Box<dyn std::error::Error>> {
let config = Config::new(WIDTH, HEIGHT, WHITE, Some(BLACK), "output.png", None);
let mut image = Image::new();
let circle = Components::Circle(config.width / 2, config.height / 2, 300, RED);
image.config(config).init()?.add_component(&circle).draw()?;
Ok(())
}
Output:
