Rounding corners in Roku app development involves applying a mask to images or elements to achieve the desired rounded appearance. This technique utilizes a rounded mask image, which is applied over the target element, effectively masking out the corners and creating a rounded effect.

Here’s how it works:
1. The rounded mask image (🖼️) is placed over the target element (🖼️) within the mask group (🛡️).
2. The mask group effectively hides the corners of the target element that fall outside the rounded shapes of the mask image, creating a rounded effect.

Code Implementation: Let’s dive into the code snippet below, which demonstrates how to implement rounded corners using a mask in Roku app development:

<!-- RoundedCorner.xml -->
<children>
<MaskGroup id="roundedMask" maskUri="pkg:/images/rounded_mask.png">
<Poster id="roundedImage" uri="pkg:/images/example_image.jpg" />
</MaskGroup>
</children>
