首先定义一个字符串变量base64Image,用于存储base64编码的图片字符串。 使用Base64类的getDecoder()方法获取Base64.Decoder对象,调用其decode()方法将base64Image解码为字节数组imageBytes。 在try-catch块中,使用ImageIO类的read()方法将字节数组转换为BufferedImage对象bufferedImage。 最后,使用ImageIO类的write()方法...

将本地图片文件转成Base64编码、InputStream、BufferedImage等流对象。工具/原料 Eclipse 依赖的jar包：sun.misc.BASE64Decoder.jar 方法/步骤 1 将本地图片文件转成Base64字符串，需要一个参数：本地图片路径public static String GetImageStr(String imgFilePath) {// 将图片文件转化为字节数组字符串，并对其进行...
World's Simplest Image Tool Free online base64 WebP decoder. Just drag and drop your base64 here and it will be automatically converted to a WebP image. View the decoded image in an online preview and download it in the modern WebP format. Created by engineers from team Browserling. ...

, and the decoder rejects any characters outside of this set. 4. convert base64 string to image file now we have a base64 string , let’s decode it back to binary content and write to a new file: byte[] decodedbytes = base64.getdecoder().decode(encodedstring); fileutils.writebyte...
这样,就可以用ImageView.setImageBitmap(bitmap)显示图片了。 低于android2.2的版本,只需要把android2.2里的Base64.java复制到应用中就可以是用: public class Base64 { /** * Default values for encoder/decoder flags. */ public static final int DEFAULT = 0; ...
