conversion of byte array into image(blob) in java [duplicate]


This question already has an answer here:

<ul><li> <a href="/questions/10849893/how-to-convert-byte-array-to-blob" dir="ltr" rel="nofollow">How to convert byte array to blob</a> <span class="question-originals-answer-count"> 1 answer </span> </li> </ul>

The code for the image conversion from byte array to image i.e blob.

try { Blob image_vis = rs1.getBlob(10); InputStream x=image_vis.getBinaryStream(); OutputStream out=new FileOutputStream(string_op); byte[] bytes = string_op.getBytes(); String s=new String(bytes); System.out.println(+s); //prints bytes for the string ImageIcon icon_cap = new ImageIcon(string_op); image_cap.setIcon(icon_cap); //prints nothing to Jlabel //image_cap.setText(s); //prints a path of a image }

I am able to get path of an image, but I am anable to convert it into image format, so that it will display on a form. please help me.


Try This..

try { Blob image_vis = rs1.getBlob("blobColumn"); int blobLength = (int) image_vis.length(); byte[] bytes = image_vis.getBytes(1, blobLength); image_vis.free(); final BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(bytes)); ImageIO.write(bufferedImage, "jpg", new File("ImagePath/ImageName.jpg")); }

Later you can pick up the image..
