### 1- add below import in your code :
```js
import { SliderBox } from "react-native-image-slider-box";
```
### 2- Define your image array source, for below examples i create array in state.
```js
export default class App extends Component {
constructor(props) {
super(props);
this.state = {
images: [
"https://source.unsplash.com/1024x768/?nature",
"https://source.unsplash.com/1024x768/?water",
"https://source.unsplash.com/1024x768/?girl",
"https://source.unsplash.com/1024x768/?tree", // Network image
require('./assets/images/girl.jpg'), // Local image
]
};
}
// other component code ...
}
```
### 3- Use SliderBox such as these below examples :
### Example 1 : SliderBox without and handler or customization
```js
```
### Example 2 : SliderBox with image press handler and currentImageEmitter
```js
console.warn(`image ${index} pressed`)}
currentImageEmitter={index => console.warn(`current pos is: ${index}`)}
/>
```
### Example 3 : SliderBox with image press handler and change slider height (default is 200)
```js
console.warn(`image ${index} pressed`)}
/>
```
### Example 4 : SliderBox with custom width from parent. use `onLayout` function by calling it from `root View` of component.
```js
onLayout = e => {
this.setState({
width: e.nativeEvent.layout.width
});
};
```
```js
render() {
return (
console.warn(`image ${index} pressed`)
}
parentWidth={this.state.width}
/>
);
}
```
### Example 5 : SliderBox with custom dots color
```js
console.warn(`image ${index} pressed`)}
dotColor="#FFEE58"
inactiveDotColor="#90A4AE"
/>
```
### Example 6 : SliderBox with custom dot style
```js
console.warn(`image ${index} pressed`)}
dotColor="#FFEE58"
inactiveDotColor="#90A4AE"
dotStyle={{
width: 15,
height: 15,
borderRadius: 15,
marginHorizontal: 10,
padding: 0,
margin: 0
}}
/>
```
### Example 7 : SliderBox with change paging box padding (Vertical height from bottom of SliderBox) + add `autoplay` and `circleLoop` attribute for jump to the first image after swipe the last one.
```js
console.warn(`image ${index} pressed`)}
dotColor="#FFEE58"
inactiveDotColor="#90A4AE"
paginationBoxVerticalPadding={20}
autoplay
circleLoop
/>
```
### Example 8 : use `Custom Image Component`, customize pagination, image `modes` and dotStyles:
```js
console.warn(`image ${index} pressed`)}
dotColor="#FFEE58"
inactiveDotColor="#90A4AE"
paginationBoxVerticalPadding={20}
autoplay
circleLoop
resizeMethod={'resize'}
resizeMode={'cover'}
paginationBoxStyle={{
position: "absolute",
bottom: 0,
padding: 0,
alignItems: "center",
alignSelf: "center",
justifyContent: "center",
paddingVertical: 10
}}
dotStyle={{
width: 10,
height: 10,
borderRadius: 5,
marginHorizontal: 0,
padding: 0,
margin: 0,
backgroundColor: "rgba(128, 128, 128, 0.92)"
}}
ImageComponentStyle={{borderRadius: 15, width: '97%', marginTop: 5}}
imageLoadingColor="#2196F3"
/>
```
### Example 9 : SliderBox with activeOpacity:
```js
```
## Full-Component(Screen) Example:
```js
import React, { Component } from "react";
import { StyleSheet, Text, View } from "react-native";
import { SliderBox } from "react-native-image-slider-box";
export default class App extends Component {
constructor(props) {
super(props);
this.state = {
images: [

"https://source.unsplash.com/1024x768/?water",
"https://source.unsplash.com/1024x768/?girl",
"https://source.unsplash.com/1024x768/?tree",
require('./assets/images/girl.jpg'),
]
};
}
render() {
