Hide sensitive areas of a screencast
You can now automatically hide parts of images or videos. This is useful for
screencasts where you don’t want to show sensitive information. Use the new
style property to create masked areas of videos or background
images, and hide sensitive areas such as password or credit card fields.
Callouts can be used to highlight parts of images. From today, you can use an additional style property on a callout to turn it from a highlight into a mask. This will draw a black rectangle over a sensitive area of your recording, so you do not have to worry about exposing private data. For example, the following piece of code will paint a black rectangle when showing the payment.mp4 video in a scene.
!(payment.mp4) (callout: type: rectangle style: mask left: 717 top: 350 right: 997 bottom: 388 )
style property in the second line of the callout. That is what turns it from a highlight into a mask.
For more information, see the callout documentation, and check out the Callouts example on GitHub for a full working demo.
