Convert Byte [] to BufferedImage

[Smily]

I was wondering if any can show me how to create a bufferedImage from a byte []. I saw an example on the forums here that converts a bufferedImage to a byte []. So I thought someone might know. Thanks


The following was the code I found

Code:

private byte[] image_byte_data(BufferedImage image)
{
    WritableRaster raster = image.getRaster();
    DataBufferByte buffer = (DataBufferByte)raster.getDataBuffer();
    return buffer.getData();
}

Java 2D - How to convert byte[] to BufferedImage

Thanks for the response, however there is one particular part I'm stuck at. Is there a way to convert a byte [] to an bufferedimage without knowing the original height of the Image. For example, you take a bufferedimage convert it to byte [], then you store it into a database. Some point later you come back and just want to reconstruct the image using the byte array.

So my question would be, before I convert a bufferedimage to a byte [] should I also save the length and width of the image into the database so that I can reconstruct the image back up? The reason I'm asking this is because the images are all of different size.

"should I also save the length and width ?"
Yes. byte[] only gives the pixels.
