# Configure the Scan Region Style

## Visibility

After you call `setScanRegion`, the scan region is visible by default. You can hide it by calling `setScanRegionMaskVisible`.

<div class="sample-code-prefix"></div>
>- Java
>- Kotlin
>
>1. 
```java
try {
   mCamera.setScanRegion(new DSRect(0.15f, 0.25f, 0.85f, 0.65f, true));
} catch (CameraEnhancerException e) {
   throw new RuntimeException(e);
}
cameraView.setScanRegionMaskVisible(false);
```
2. 
```kotlin
try {
   mCamera.setScanRegion(DSRect(0.15f, 0.25f, 0.85f, 0.65f, true))
} catch (e: CameraEnhancerException) {
   throw RuntimeException(e)
}
cameraView.setScanRegionMaskVisible(false)
```

## Scan Region Mask Style

The scan region mask style includes the stroke color, stroke width, and mask color.

<div align="center">
    <p><img src="../../../assets/scan-region-style.png" width="70%" alt="scan-region-style"></p>
    <p>Scan Region Style</p>
</div>

1. Add your colors to `res/values/colors.xml`.

```xml
<color name="teal_200">#FF03DAC5</color>
<color name="teal_200_transparent">#2003DAC5</color>
```

2. Set colors to the scan region mask style.

<div class="sample-code-prefix"></div>
>- Java
>- Kotlin
>
>1. 
```java
int teal_200_transparent = ResourcesCompat.getColor(MainActivity.this.getResources(), R.color.teal_200_transparent, null);
int teal_200 = ResourcesCompat.getColor(MainActivity.this.getResources(), R.color.teal_200, null);
cameraView.setScanRegionMaskStyle(teal_200, teal_200_transparent, 2.0f);
```
2. 
```kotlin
val teal_200_transparent = ResourcesCompat.getColor(this@MainActivity.getResources(), R.color.teal_200_transparent, null)
val teal_200 = ResourcesCompat.getColor(this@MainActivity.getResources(), R.color.teal_200, null)
cameraView.setScanRegionMaskStyle(teal_200, teal_200_transparent, 2.0f)
```

## Laser

The scan laser is a light bar that moves up and down to indicate active scanning. It does not affect performance. It is hidden by default. When a scan region is set, the laser movement is limited to that region.

<div class="sample-code-prefix"></div>
>- Java
>- Kotlin
>
>1. 
```java
cameraView.setScanLaserVisible(true);
```
2. 
```kotlin
cameraView.setScanLaserVisible(true)
```
