如何在angular中将缓冲区数据转换为base64图像

import { Component } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';

export class YourComponent {
  constructor(private sanitizer: DomSanitizer) {}

  convertBufferToBase64(buffer: ArrayBuffer): string {
    const bytes = new Uint8Array(buffer);
    let binary = '';
    for (let i = 0; i < bytes.length; i++) {
      binary += String.fromCharCode(bytes[i]);
    }
    const base64String = window.btoa(binary);
    return 'data:image/png;base64,' + base64String;
  }
}

const bufferData = ...; // 从缓冲区获取的数据
const base64Image = this.convertBufferToBase64(bufferData);
