Shapes for Graphics

Contains code to make and alter various shapes.

Primarily designed to be used with Buffer Graphics and Pixels graphics lib

Usage

Add this line to Cargo.toml ```toml graphics-shapes = "0.2.2"

or with both features

graphics-shapes = {version = "0.2.2", features = ["mint", "serde"] } ```

Examples

```rust let rect = Rect::new((10,10),(20,20)); assert!(rect.contains(coord!(15,15))); let triangle = Triangle::new((34,5),(12,30),(9,10)); let rotated = triangle.rotate(45);

let start = coord!(20,130); let dist = start.distance((30,130)); ```

Shapes

• Line
• Rect
• Triangle
• Circle
• Ellipse
• Polygon

Shared methods

• contains (Coord | Shape) - Returns true if param is entirely inside
• intersects (Shape) - Returns true if param is partially inside/touching
• outline_pixels - Returns a list of points that can be used to draw a stroke version
• filled_pixels - Returns a list of points that can be used to draw a filled version
• rotate, scale, transform - Copy and change the shape

Per shape methods

All the shapes have methods to create similar sized shapes of different types, e.g. Circle::to_outer_rect(), Rect::to_triangles()

Working with multiple shapes

Each Shape is a separate struct so to store them without putting them in a Box you can use ShapeBox which implements Shape and so is fully compatible with other Shapes and their methods.

Assertions

This library uses debug assertions for some methods.

Features

Both are off by default

Serde

serde adds serde::{Serialize, Deserialize} to Coord, Line, Rect, Circle, Triangle, Ellipse, Polygon

Mint

mint adds a From impl for Point2<isize> to Coord

Known issues

• Ellipses don't render correctly when rotated
