Adding Media with Image Rotation Functionality in PowerApps

Introducing the efficient way to enhance your PowerApps experience by enabling image rotation functionality! Ever faced issues with images being uploaded in the wrong orientation? Or wished you had a way to correct an upside-down image? In this guide, we will delve into how you can add buttons to your image control in PowerApps, allowing users to rotate their images both clockwise and anti-clockwise.

Getting Started with Image Controls

The magic happens with the help of the ImageRotation property of the image control. This specific property can take one of four values – None, Rotate90, Rotate180, and Rotate270.

Start by adding an image control to your screen in PowerApps.

Integrating Rotate Buttons

For this functionality, we’ll use a local variable to keep track of the current rotation. The clockwise button will increase this value by 90°, and the anti-clockwise button will decrease it by the same.

In the OnVisible property of your screen, initialize this variable with:

UpdateContext({rotationVar:ImageRotation.None})

Add the ‘rotate clockwise’ button and set its OnSelect property using this formula:

Switch(rotationVar,
           ImageRotation.None, UpdateContext({rotationVar:ImageRotation.Rotate90}),
           ImageRotation.Rotate90, UpdateContext({rotationVar:ImageRotation.Rotate180}),
           ImageRotation.Rotate180, UpdateContext({rotationVar:ImageRotation.Rotate270}),
           ImageRotation.Rotate270, UpdateContext({rotationVar:ImageRotation.None}),
           UpdateContext({rotationVar:ImageRotation.None})
    )

Next, integrate the ‘rotate anti-clockwise’ button with this formula:

Switch(rotationVar,
           ImageRotation.None, UpdateContext({rotationVar:ImageRotation.Rotate270}),
           ImageRotation.Rotate90, UpdateContext({rotationVar:ImageRotation.None}),
           ImageRotation.Rotate180, UpdateContext({rotationVar:ImageRotation.Rotate90}),
           ImageRotation.Rotate270, UpdateContext({rotationVar:ImageRotation.Rotate180}),
           UpdateContext({rotationVar:ImageRotation.None})
    )

Lastly, link the ImageRotation property of the image control to the rotationVar variable. Once set up, you can test the functionality within your app.
