[−][src]Struct embedded_graphics::geometry::Point
2D point.
A point can be used to define the position of a graphics object. For example, a Rectangle
may be defined that has its top left corner at (-1, -2)
. To specify the size of an object
Size
should be used instead.
Nalgebra support can be enabled with the nalgebra_support
feature. This implements
From<Vector2<N>>
and From<&Vector2<N>>
where N
is Scalar + Into<i32>
. This allows use
of Nalgebra's Vector2
with embedded-graphics where i8
, i16
, i32
, u16
or u8
is used
for value storage.
Examples
Create a Point
from two integers
use embedded_graphics::geometry::Point; // Create a coord using the `new` constructor method let p = Point::new(10, 20);
Create a Point
from a Nalgebra Vector2
Be sure to enable the nalgebra_support
feature to get Nalgebra integration.
use embedded_graphics::geometry::Point; use nalgebra::Vector2; let n_coord = Vector2::new(10i32, 20); assert_eq!(Point::from(n_coord), Point::new(10, 20));
Convert a Vector2<u8>
into a Point
Be sure to enable the nalgebra_support
feature to get Nalgebra integration.
Smaller unsigned types that can be converted to i32
are also supported in conversions.
use embedded_graphics::geometry::Point; use nalgebra::Vector2; let n_coord = Vector2::new(10u8, 20); assert_eq!(Point::from(n_coord), Point::new(10, 20));
Fields
x: i32
The x coordinate.
y: i32
The y coordinate.
Methods
