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[]));

how to get coordinates of an image and convert into matrix or multidimensional array in array?

following is image to byte array.
Imports System.IO
Imports System.Drawing.Printing
Imports RasterEdge.Imaging
Imports RasterEdge.Imaging.Processing
Imports RasterEdge.Imaging.Converting.ImageToByte

Dim Image As New RasterEdgeImaging()
If True Then
Dim image As New MemoryStream()
ImageID.Save(image, System.Drawing.Imaging.ImageFormat.Jpeg)
Return ms.ToArray()
End If
Image.save()
