Here is an example process for converting an image from a backend server into a byte array and displaying it as the background image in an HTML DIV style in Angular:
const reader = new FileReader();
reader.onloadend = () => {
const bytes = new Uint8Array(reader.result as ArrayBuffer);
// Use the byte array to set the background image style
};
reader.readAsArrayBuffer(imageData);
const divElement = document.getElementById('my-div');
divElement.style.backgroundImage = `url("data:image/jpeg;base64,${btoa(String.fromCharCode.apply(null, bytes))}")`;
In this example, "my-div" is the ID of the HTML DIV element, and the byte array is converted into a base64-encoded string to be used in the "url" parameter of the background image style.
