How do I read an image from a byte array in Java?

java Add comments

Create a ByteArrayInputStream from your byte array and then use ImageIO class to read image from that stream.


InputStream in = new ByteArrayInputStream(bytearray);
BufferedImage image = ImageIO.read(in);

Hey,
This solution is worked well but when try to use same at google app engine, I’m not able to do.
Google app engine doesn’t support BufferedImage or ImageIO
I’m wondering about how it could be implemented.
you can find the whitelist of GAE for JAVA at http://code.google.com/appengine/docs/java/jrewhitelist.html

I’m having a webservice on which the image is passed as byte array from web client.

Could you please suggest any way. Thanks in advance.
