Sending Bitmap using WCF

Dec 27th, 2008

Hi,
I'm trying to send a bitmap using WCF and here's the steps i followed:
1-Convert it into byte array

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
private IDataObject tempObj;
private System.Drawing.Image tempImg;
tempObj = Clipboard.GetDataObject();
tempImg = (System.Drawing.Bitmap)tempObj.GetData(System.Windows.Forms.DataFormats.Bitmap);
tempImg.Save("hello.bmp");
VideoData = System.IO.File.ReadAllBytes("hello.bmp");
private IDataObject tempObj;
private System.Drawing.Image tempImg;
tempObj = Clipboard.GetDataObject();
tempImg = (System.Drawing.Bitmap)tempObj.GetData(System.Windows.Forms.DataFormats.Bitmap);
tempImg.Save("hello.bmp");
VideoData = System.IO.File.ReadAllBytes("hello.bmp");

2-Receiving the byte array from the other client side and convert it into bitmap to display it

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
public void ReceiveByteArray(byte[] Data)
        {
            try
            {
                TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));
                Bitmap bitmap1 = (Bitmap)tc.ConvertFrom(Data);
 
                pictureBox2.Image = bitmap1;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }
public void ReceiveByteArray(byte[] Data)
        {
            try
            {
                TypeConverter tc = TypeDescriptor.GetConverter(typeof(Bitmap));
                Bitmap bitmap1 = (Bitmap)tc.ConvertFrom(Data);

                pictureBox2.Image = bitmap1;
            }
            catch (Exception ex)
            {
                MessageBox.Show(ex.Message);
            }

i don't know why pictureBox.Image is always black...it doesn't display the image,although the "hello.bmp" file on the hard disk changes while catching the picture.

N.B the byte array "Data" isn't set to null it contains the values i sent from the other client side.

If you saved this bitmap on client's HDD, what the result, also black?

Check if your array comes in order or not.

Yes it comes in order and everything is okay...it was a matter of format.

 Help with Code Tags 
 C# Syntax (Toggle Plain Text) 
private void WebCamCapture_ImageCaptured(object source, WebcamEventArgs e)
        {
            // set the picturebox picture
            MemoryStream ms = new MemoryStream();
            e.WebCamImage.Save(ms, ImageFormat.Jpeg);
 
            proxy.SendShot(new SimpleSvc.VideoChat(ms.ToArray(),lstContacts.SelectedItem.ToString()));
 
            this.pictureBox1.Image = e.WebCamImage;
        }
private void WebCamCapture_ImageCaptured(object source, WebcamEventArgs e)
        {
            // set the picturebox picture
            MemoryStream ms = new MemoryStream();
            e.WebCamImage.Save(ms, ImageFormat.Jpeg);

            proxy.SendShot(new SimpleSvc.VideoChat(ms.ToArray(),lstContacts.SelectedItem.ToString()));

            this.pictureBox1.Image = e.WebCamImage;
        }

Thanks for help
