## ⚙️ Installation
```bash
$ npm install overlap-area
```
```html
```
## 🚀 How to use
```ts
import { isInside, getOverlapPoints, getOverlapSize } from "overlap-area";
const points1 = [
[0, 0],
[100, 0],
[120, 100],
[0, 100],
];
const points2 = [
[100, 0],
[150, 0],
[150, 100],
[100, 100],
];
// true
console.log(isInside([50, 50], points1));
// false
console.log(isInside([50, 50], points2));
// [100, 0], [120, 100], [100, 100]
console.log(getOverlapPoints(points1, points2));
// 1000
console.log(getOverlapSize(points1, points2));
```
### User Overlap Areas
Get the areas of the overlapped part of two shapes.
```js
import { getOverlapAreas } from "overlap-area";
const points1 = [
[150, 100],
[200, 50],
[250, 60],
[300, 100],
[250, 160],
[150, 150],
[200, 120],
];
const points2 = [
[250, 100],
[300, 50],
[350, 60],
[400, 100],
[350, 160],
[220, 150],
[300, 120],
];
/*
[
[
[272.2222222, 77.7777778],
[300, 100],
[287.5, 115],
[250, 100],
],
[
[275.7575758, 129.0909091],
[256.0240964, 152.7710843],
[220, 150],
],
]
*/
console.log(getOverlapAreas(points1, points2));
```
### User Unoverlap Areas
Get non-overlapping areas of two shapes based on points1.
```js
import { getUnoverlapAreas } from "overlap-area";
const points1 = [
[150, 100],
[200, 50],
[250, 60],
[300, 100],
[250, 160],
[150, 150],
[200, 120],
];
const points2 = [
[250, 100],
[300, 50],
[350, 60],
[400, 100],
[350, 160],
[220, 150],
[300, 120],
];
/*
[
[
[150, 100],
[200, 50],
[250, 60],
[272.2222222, 77.7777778],
[250, 100],
[287.5, 115],
[275.7575758, 129.0909091],
[220, 150],
[256.0240964, 152.7710843],
[250, 160],
[150, 150],
[200, 120],
],
]
*/
console.log(getUnoverlapAreas(points1, points2));
```
### Calculate the overlap of elements
```js
import { getElementInfo } from "moveable";
import { getOverlapPoints, getOverlapSize } from "overlap-area";
function getPoints(info) {
const { left, top, pos1, pos2, pos3, pos4 } = info;
return [pos1, pos2, pos4, pos3].map(pos => [left + pos[0], top + pos[1]]);
}
const points1 = getPoints(getElementInfo(element1));
const points2 = getPoints(getElementInfo(element2));
// Points of the overlapped area
getOverlapPoints(points1, points2);
// Size of the overlapped area
getOverlapSize(points1, points2);
```
