Enum Shape

Source

pub enum Shape {
    Path(PathShape),
    Rect(RectShape),
}

Expand description

Represents a graphical shape, which can be either a custom path or a simple rectangle.

§Variants

Path(PathShape): A custom path shape defined using Bézier curves and lines.
Rect(RectShape): A simple rectangular shape with optional rounded corners.

§Examples

use grafo::Color;
use grafo::Stroke;
use grafo::{Shape, BorderRadii};

// Create a simple rectangle
let rect = Shape::rect(
    [(0.0, 0.0), (100.0, 50.0)],
    Color::rgb(255, 0, 0), // Red fill
    Stroke::new(2.0, Color::BLACK), // Black stroke with width 2.0
);

// Create a custom path shape
let custom_path = Shape::builder()
    .fill(Color::rgb(0, 255, 0))
    .stroke(Stroke::new(1.0, Color::BLACK))
    .begin((0.0, 0.0))
    .line_to((50.0, 10.0))
    .line_to((50.0, 50.0))
    .close()
    .build();

Implementations§

Source §

impl Shape

Source

pub fn builder() -> ShapeBuilder

Creates a new ShapeBuilder for constructing complex shapes.

§Examples

use grafo::Shape;

let builder = Shape::builder();

Source

pub fn rect(rect: [(f32, f32); 2], fill_color: Color, stroke: Stroke) -> Shape

Creates a simple rectangle shape with the specified coordinates, fill color, and stroke.

§Parameters

rect: An array containing two tuples representing the top-left and bottom-right coordinates of the rectangle.
fill_color: The fill color of the rectangle.
stroke: The stroke properties of the rectangle.

§Examples

use grafo::Color;
use grafo::Stroke;
use grafo::Shape;

let rect = Shape::rect(
    [(0.0, 0.0), (100.0, 50.0)],
    Color::rgb(255, 0, 0), // Red fill
    Stroke::new(2.0, Color::BLACK), // Black stroke with width 2.0
);

Source

pub fn rounded_rect( rect: [(f32, f32); 2], border_radii: BorderRadii, fill_color: Color, stroke: Stroke, ) -> Shape

Creates a rectangle shape with rounded corners.

§Parameters

rect: An array containing two tuples representing the top-left and bottom-right coordinates of the rectangle.
border_radii: The radii for each corner of the rectangle.
fill_color: The fill color of the rectangle.
stroke: The stroke properties of the rectangle.

§Examples

use grafo::Color;
use grafo::Stroke;
use grafo::{Shape, BorderRadii};

let rounded_rect = Shape::rounded_rect(
    [(0.0, 0.0), (100.0, 50.0)],
    BorderRadii::new(10.0),
    Color::rgba(0, 255, 0, 128), // Semi-transparent green fill
    Stroke::new(1.5, Color::BLACK), // Black stroke with width 1.5
);
