Hello convert image to bitmap image If I understand your question correctly what you want is not how to convert the image but how to get the Stream. I would simply write a function which takes the path of the image as the first Parameter: public Byte[] BufferFromImage(string path) { StreamReader streamreader = new StreamReader(path); Byte[] buffer = null; Stream stream = streamreader.BaseStream; if (stream != null && stream.Length > 0) { using (BinaryReader br = new BinaryReader(stream)) { buffer = br.ReadBytes((Int32)stream.Length); } } return buffer; }
