Convert Images into a byte array.

[JLRodz]

Hi,

I need to know is there is a way to convert a Image into a array of bytes? I know a way using BufferedInputStream but that is loading a image from a file. I need to know a way to do it, if I already have an Image loaded in my class. Thanks in advance.

you could probably turn the picture into an array of bytes by serializing it. Something like...

public static byte[] serializeObj(Object obj) throws IOException
{
ByteArrayOutputStream baOStream = new ByteArrayOutputStream();
ObjectOutputStream objOStream = new ObjectOutputStream(baOStream);

objOStream.writeObject(obj); //object must be serializable
objOStream.flush();
objOStream.close();
return baOStream.toByteArray(); //returns stream as byte array
}

Image im = ...

ImageConverter converter = new ImageConverter();
Byte[] imageByteArray = (byte[]) converter.ConvertTo(im, typeof(byte[]));
