I am working on event image upload functionality in Angular, where I require to implement same functionality as facebook cover upload wherein we have fixed div or container if user upload a image we have to adjust it according to the div or container.

For reference: https://youtu.be/LRxDFwJzzv8

As shown in video I need same functionality. It will be great if someone can help me with code reference or any npm library.

Thanks in anticipation.
