Function viuer::terminal_size

pub fn terminal_size() -> (u16, u16)

Try to get the terminal size. If unsuccessful, fallback to a default (80x24).

Uses crossterm::terminal::size.

Example

The example below prints “img.jpg” with dimensions 80x40 in the center of the terminal.

use viuer::{Config, print_from_file, terminal_size};

let (term_width, term_height) = terminal_size();
// Set desired image dimensions
let width = 80;
let height = 40;

let config = Config {
    x: (term_width - width) / 2,
    y: (term_height - height) as i16 / 2,
    width: Some(width as u32),
    height: Some(height as u32),
    ..Default::default()
};
print_from_file("img.jpg", &config).expect("Image printing failed.");
