Expand description

2D size.

Size is used to define the width and height of an object.

Nalgebra support can be enabled with the nalgebra_support feature. This implements From<Vector2<N>> and From<&Vector2<N>> where N is Scalar + Into<u32>. This allows use of Nalgebra’s Vector2 with embedded-graphics where u32, u16 or u8 is used for value storage.

Examples

Create a Size from two integers

use embedded_graphics::geometry::Size;

// Create a size using the `new` constructor method
let s = Size::new(10, 20);

Create a Size from a Nalgebra Vector2

Be sure to enable the nalgebra_support feature to get Nalgebra integration.

Any Vector2<N> can be used where N: Into<u32> + nalgebra::Scalar. This includes the primitive types u32, u16 and u8.

use embedded_graphics::geometry::Size;
use nalgebra::Vector2;

assert_eq!(Size::from(Vector2::new(10u32, 20)), Size::new(10u32, 20));
assert_eq!(Size::from(Vector2::new(10u16, 20)), Size::new(10u32, 20));
assert_eq!(Size::from(Vector2::new(10u8, 20)), Size::new(10u32, 20));

.into() can also be used, but may require more type annotations:

use embedded_graphics::geometry::Size;
use nalgebra::Vector2;

let c: Size = Vector2::new(10u32, 20).into();

assert_eq!(c, Size::new(10u32, 20));

Fields

width: u32

The width.

height: u32

The height.

Implementations

Creates a size from a width and a height.

Creates a size with width and height set to an equal value.

use embedded_graphics::geometry::Size;

let size = Size::new_equal(11);

assert_eq!(
    size,
    Size {
        width: 11,
        height: 11
    }
);

Creates a size with width and height equal to zero.

Returns a size with equal width value and height set to 0.

Examples
Move a Point along the X axis.
use embedded_graphics::geometry::{Point, Size};

let size = Size::new(20, 30);

let point = Point::new(10, 15);

let moved_x = point + size.x_axis();

assert_eq!(moved_x, Point::new(30, 15));

Returns a size with equal height value and width set to 0.

Examples
Move a Point along the Y axis.
use embedded_graphics::geometry::{Point, Size};

let size = Size::new(20, 30);

let point = Point::new(10, 15);

let moved_y = point + size.y_axis();

assert_eq!(moved_y, Point::new(10, 45));

Saturating addition.

Returns u32::max_value() for width and/or height instead of overflowing.

Saturating subtraction.

Returns 0 for width and/or height instead of overflowing, if the value in other is larger then in self.

Returns the componentwise minimum of two Sizes.

use embedded_graphics::geometry::Size;

let min = Size::new(20, 30).component_min(Size::new(15, 50));

assert_eq!(min, Size::new(15, 30));

Returns the componentwise maximum of two Sizes.

use embedded_graphics::geometry::Size;

let min = Size::new(20, 30).component_max(Size::new(15, 50));

assert_eq!(min, Size::new(20, 50));

Returns the componentwise multiplication of two Sizes.

use embedded_graphics::geometry::Size;

let result = Size::new(20, 30).component_mul(Size::new(2, 3));

assert_eq!(result, Size::new(40, 90));

Returns the componentwise division of two Sizes.

Panics

Panics if one of the components of other equals zero.

use embedded_graphics::geometry::Size;

let result = Size::new(20, 30).component_div(Size::new(5, 10));

assert_eq!(result, Size::new(4, 3));
