Configure the Scan Region Style

Visibility

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

• Java
• Kotlin

1. 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. 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.

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

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

1. Set colors to the scan region mask style.

• Java
• Kotlin

1. 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. 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.

• Java
• Kotlin

1. cameraView.setScanLaserVisible(true);
   

2. cameraView.setScanLaserVisible(true)
