Struct Window 

pub struct Window {
    pub x: u32,
    pub y: u32,
    pub w: u32,
    pub h: u32,
}

Canvas image window coordinates

Defines a rectangular window on the canvas to export the image from.

The window origin is defined by its the upper left corner.

Basic operations

use planetarium::Window;

// Create a new rectangular window with origin at (0, 0).
let wnd1 = Window::new(128, 64);

// Move the window origin to (250, 150).
let wnd2 = wnd1.at(250, 150);

// Check the resulting string representation.
assert_eq!(wnd2.to_string(), "(250, 150)+(128, 64)");

Conversions

// From a tuple of tuples representing the origin coordinates
// and window dimensions
let wnd1 = Window::from(((100, 200), (128, 128)));

// Check the resulting string representation.
assert_eq!(wnd1.to_string(), "(100, 200)+(128, 128)");

Fields

x: u32

Window origin X coordinate

y: u32

Window origin Y coordinate

w: u32

Width in X direction

h: u32

Height in Y direction
