# rebounds.js [](https://travis-ci.org/hanamura/rebounds.js)
Rectangle scaling functions.
## Installation
```sh
npm install rebounds
```
## Functions
### rebounds.fit(space, rect, options = {positionX: 0.5, positionY: 0.5, reduce: true, expand: true})
alias: **rebounds.showAll**
Returns scaled `rect` bounds to fit into `space`.
```javascript
rebounds.fit(
{width: 100, height: 100},
{width: 200, height: 50}
);
// => {width: 100, height: 25, x: 0, y: 37.5}
rebounds.fit(
{width: 100, height: 100},
{width: 200, height: 50},
{reduce: false}
);
// => {width: 200, height: 50, x: -50, y: 25}
```
### rebounds.fill(space, rect, options = {positionX: 0.5, positionY: 0.5, reduce: true, expand: true})
alias: **rebounds.noBorder**
Returns scaled `rect` bounds to fill `space`.
```javascript
rebounds.fill(
{width: 100, height: 100},
{width: 200, height: 50}
);
// => {width: 400, height: 100, x: -150, y: 0}
rebounds.fill(
{width: 100, height: 100},
{width: 200, height: 50},
{expand: false}
);
// => {width: 200, height: 50, x: -50, y: 25}
```
### rebounds.remain(space, rect, options = {positionX: 0.5, positionY: 0.5})
alias: **rebounds.noScale**
Returns non-scaled `rect` bounds repositioned against `space`.
```javascript
rebounds.remain(
{width: 100, height: 100},
{width: 200, height: 50}
);
// => {width: 200, height: 50, x: -50, y: 25}
```
### rebounds.stretch(space, rect, options = {positionX: 0.5, positionY: 0.5})
alias: **rebounds.exactFit**
Returns `rect` bounds stretched into the same size with `space`.
```javascript
rebounds.stretch(
{width: 100, height: 100},
{width: 200, height: 50}
);
// => {width: 100, height: 100, x: 0, y: 0}
```
### rebounds.position(space, rect, options = {positionX: 0.5, positionY: 0.5})
Returns coordinates of `rect` repositioned against `space`.
```javascript
rebounds.position(
{width: 100, height: 100},
{width: 200, height: 50}
);
// => {x: -50, y: 25}
rebounds.position(
{width: 100, height: 100, x: 50, y: 50},
{width: 200, height: 50}
);
// => {x: 0, y: 75}
rebounds.position(
{width: 100, height: 100},
{width: 200, height: 50},
{
positionX: rebounds.LEFT, // rebounds.LEFT === 0
positionY: rebounds.BOTTOM // rebounds.BOTTOM === 1
}
);
// => {x: 0, y: 50}
```
