使用Base64.getDecoder().decode(base64String)方法将Base64字符串解码为字节数组。 使用ByteArrayInputStream将字节数组转换为输入流: 创建一个ByteArrayInputStream对象,将字节数组作为数据源。 使用ImageIO.read(InputStream)从输入流中读取并创建BufferedImage对象: 调用ImageIO.read()方法,将输入流读取为BufferedImage...
val base64String = "your_base64_string_here" val imageBitmap = base64ToImage(base64String) 这样,你就可以使用imageBitmap变量来显示或处理转换后的图像了。 关于Base64字符串转换为图像的优势是可以方便地在网络传输中传递图像数据,而不需要单独传输图像文件。它在移动应用开发中常用于接收服务器返回...
