本文實例為大家分享了Java將圖片轉二進制再將二進制轉成圖片，供大家參考，具體內容如下
import java.awt.image.BufferedImage; import java.io.ByteArrayInputStream; import java.io.ByteArrayOutputStream; import java.io.File; import java.io.IOException; import javax.imageio.ImageIO; import sun.misc.BASE64Decoder; import sun.misc.BASE64Encoder; public class TestImageBinary { static BASE64Encoder encoder = new sun.misc.BASE64Encoder(); static BASE64Decoder decoder = new sun.misc.BASE64Decoder(); public static void main(String[] args) { System.out.println(getImageBinary()); base64StringToImage(getImageBinary()); } static String getImageBinary(){ File f = new File("c://20090709442.jpg"); BufferedImage bi; try { bi = ImageIO.read(f); ByteArrayOutputStream baos = new ByteArrayOutputStream(); ImageIO.write(bi, "jpg", baos); byte[] bytes = baos.toByteArray(); return encoder.encodeBuffer(bytes).trim(); } catch (IOException e) { e.printStackTrace(); } return null; } static void base64StringToImage(String base64String){ try { byte[] bytes1 = decoder.decodeBuffer(base64String); ByteArrayInputStream bais = new ByteArrayInputStream(bytes1); BufferedImage bi1 =ImageIO.read(bais); File w2 = new File("c://QQ.bmp");//可以是jpg,png,gif格式ImageIO.write(bi1, "jpg", w2);//不管輸出什麼格式圖片，此處不需改動} catch (IOException e) { e.printStackTrace(); } } }以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持武林網。
