我有这个代码
def test(base64:String){ Logger.debug(“ ImageHelper.test”)
var test = Base64.getDecoder.decode(base64);
// var input_stream: ByteArrayInputStream = new ByteArrayInputStream(test);
var input_stream = new ByteArrayInputStream(test);
// var final_buffered_image: BufferedImage = ImageIO.read(input_stream);
// ImageIO.write(final_buffered_image , "jpg", new File("final_file.jpg") );
val size100 = Image.fromStream(new FileInputStream(base64)).scaleTo(100, 100)
// val size100 = Image.fromStream(input_stream).scaleTo(100, 100) }
如何将input_stream变量(哪个是ByteArrayInputStream)转换为文件或图像?
