Thread: How Convert a Byte array to a image format

Hi,
How to convert a Byte array to and image format....I shall be more clear what i want...See i recieve a Byte array fom server which was converted from an image/text format into a Byte array....i recieve this Byte array I have to convert this Byte array into their respective image and text format....please tell me how to convert a Byte array to a image ......... Kindly explain clearly as i am new to Java......

Thanking You.

How about this.

        try {
            final BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(myByteArray));
        } catch (IOException e) {
            e.printStackTrace();
        }

// Json

Json then will this BufferedImage will contain jpeg format file..........

It will just contain the image data, what would you like to do with the image after this?

// Json

after converting what i need is a file with .jpeg extendsion and i store it in the local disk and will open when required................is the output from
final BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(myByteArray));
a jpeg file so that i can open it after storing it...................
Thank u...

Well in that case we need to expand the code somewhat.

 
        try {
            final BufferedImage bufferedImage = ImageIO.read(new ByteArrayInputStream(myByteArray));
            ImageIO.write(bufferedImage, "jpg", new File("path/to/image.jpg"));
        } catch (IOException e) {
            e.printStackTrace();
        }

The line ImageIO.write will write your bufferedImage data down to your disk as file of type jpeg and it will store it at path/to/image.jpg

You can change that line slightly if you want to store it as png or something else. The bufferedImage data is just the image data, the ImageIO utility class will store that data to the format you specify when you call the write method.

// Json

Hi I am having the same problem as ammu2288 except mine is a little different i have turned an image into a byte array. however i am trying to sho the image onto a jframe and when the image comes up it justs shows me the default colorof my jframe any help would be appreciated.
Thank You
here is my code:
BufferedImage bImageFromConvert = null;

try
{
ByteArrayOutputStream baos = new ByteArrayOutputStream();
ImageIO.write(screenImage, formatName, baos);
byte[] bytesOut = baos.toByteArray();
ByteArrayInputStream in = new ByteArrayInputStream(bytesOut);
bImageFromConvert = ImageIO.read(in);
}

catch(IllegalArgumentException e)
{
}

catch(IOException e)
{
}

g.drawImage(bImageFromConvert, 0, 0, this);
