# Process image into colored ascii image
# Usage
- Render to stdout
```rust
use rascii::image_proc::ImageEngine;
use std::error::Error;
use std::io::stdout;
fn main() -> Result<(), Box<dyn Error>> {
let source = image::open("charizard.png")?;
let engine = ImageEngine::new(source);
let mut writer = stdout();
engine.render_to_text(&mut writer, 0, Some(256), None)?;
Ok(())
}
```
- Write into a file
```rust
use rustascii::{image_proc::ImageEngine};
use std::{error::Error, io::stdout};
fn main() -> Result<(), Box<dyn Error>> {
let source = include_bytes!("charizard");
let engine = ImageEngine::from_slice(source)?;
let mut file_writer = fs::File::create_new("your-new-file")?;
// If only one of the axis is set,
// the image aspect ratio will be preserved
engine.render_to_text(&mut file_writer, 0, Some(128), None)?;
Ok(())
}
```
