Props

Example

1. Simple overlay color

The most basic use-case of this module is to add colored overlay on top of your image.

<ImageOverlay source={{ uri:"http://example.com/img/cool.jpg" }} />

Default overlay is color is #000000 with 0.5 opacity. You can customize it to any color

<ImageOverlay
    source={{ uri:"http://example.com/img/cool.jpg" }}
    overlayColor="cyan"
    overlayAlpha={0.8} />

2. Overlay with title text

If you want to display a simple white text on top of the image, you can use the title prop.

<ImageOverlay
    source={{ uri:"http://example.com/img/cool.jpg" }}
    title="This is the title" />

The title will be center-ed by default. You can move it to the top or bottom using the contentPosition prop

<ImageOverlay
    source={{ uri:"http://example.com/img/cool.jpg" }}
    title="This is the title"
    contentPosition="bottom" />

Additionally, you can change the styling by passing the titleStyle along

<ImageOverlay
    source={{ uri:"http://example.com/img/cool.jpg" }}
    title="This is the title"
    titleStyle={{ color: 'yellow', fontWeight: 'bold' }} />

3. Overlay with child component

You can pass extra components to be displayed on top of your image.

<ImageOverlay
  source={{ uri:"http://example.com/img/cool.jpg" }}
  height={0.7 * height} 
  contentPosition="bottom">
    <View>
        <Image style={styles.avatar} source={{uri:"http://example.com/user/avatar.png"}} />
        <Text style={styles.name}>Amelia Edwards</Text>
        <Text style={styles.location}>Kuala Lumpur, Malaysia</Text>
        <Button text="Follow me" />
    </View>
</ImageOverlay>

Note: When you are using child component, title prop will be ignored.
