Convert (Retrieve) Image from clipboard to a byte Array in JavaScript

How to convert an image from the clipboard to a byte stream and send it to code behind

I am pasting an image in my textarea if I have any image on the clipboard.

Now when i paste the image from the clipboard I also want to read the data of the image (i mean the byte[] that forms the image) to send it to the server.

I am using Blazor so I want this to be done via JavaScript.

Any snippets?
