This article shares with you the example of Java converting pictures into binary and then binary into pictures for your reference. The specific content is as follows
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");//It can be jpg, png, gif format ImageIO.write(bi1, "jpg", w2);//No matter what format image is output, there is no need to change it here} catch (IOException e) { e.printStackTrace(); } } }The above is all the content of this article. I hope it will be helpful to everyone's learning and I hope everyone will support Wulin.com more.
