Convert a image to a monochrome byte array

Question

If you just need to convert your bitmap into a byte array, try using a MemoryStream:

Check out this link: C# Image to Byte Array and Byte Array to Image Converter Class

public byte[] imageToByteArray(System.Drawing.Image imageIn)
{
 MemoryStream ms = new MemoryStream();
 imageIn.Save(ms,System.Drawing.Imaging.ImageFormat.Gif);
 return  ms.ToArray();
}
