Image Overview

The Image component lets you display pictures in your app and pairs nicely with image based components like the Camera, Photo Library, Image Recognizer and Media DB

Set Image

There are a few ways you can display an image in your app:

  1. Take a picture with the Camera component

The blocks above open up your phone’s camera and set the Image component to the picture that you took.

Edit Image size

You can set how tall the Image is using the height property and set how wide it is using the width property.

Height

  • Fill container - The Image fills the entire screen vertically

  • Fit contents - The Image’s height changes to fit the contents it contains

With the Resize Mode property, you can do the following:

  • Cover: Resizes the picture to its max height or width regardless without changing the image quality.

  • Contain: Resizes the picture to fit the area without changing its quality

  • Stretch: The picture’s height will change to fill the image component length-wise
