to convert raw byte array(its not actual image) to Bitmap image?

Load the byte array into a memorystream, then just load the image from the memorystream

     MemoryStream ms = new MemoryStream(imgData);
     Image img = Image.FromStream(ms);

Select allOpen in new window

please shed more light on "its not actual image" if the above does nto work.

I mean, it is just a buffer of raw pixel data, and not a complete image file so  MemoryStream will not work.

I think the asker of this question: http://social.msdn.microsoft.com/Forums/en-SG/clr/thread/220095e4-0150-4c23-a613-7276494290 did it but he did not put the all code, do someone have a such code?

link seems to be invalid

also sounds like you just talking about a bitmap

     MemoryStream ms = new MemoryStream(BitmapData);
     return (new Bitmap(ms));

Select allOpen in new window

CodeCruiser I tried the function that suggested in that link:

 public Bitmap CopyDataToBitmap(byte[] data)
        {
            Bitmap bmp = new Bitmap( 900, 600, PixelFormat.Format16bppRgb565);
                       BitmapData bmpData = bmp.LockBits(new Rectangle(0, 0, bmp.Width, bmp.Height), ImageLockMode.WriteOnly, bmp.PixelFormat);
           
            Marshal.Copy(data, 0, bmpData.Scan0, data.Length);
            //set the beginning of pixel data

            bmp.UnlockBits(bmpData);
            return bmp;
        }

but the image got displayed as a black image, any suggestion?

Make sure you are using the correct format and depth.

How can I know what's the correct format & depth?

Where is the raw data coming from? You need to confirm from the source.

Actually the data is a web page request that come as stream.

A web page request? Not sure I understand.

Something like this:
HttpWebRequest httpWebRequest = (System.Net.HttpWebRequest)System.Net.HttpWebRequest.Create(url);
 System.Net.HttpWebResponse httpWebResponse = (System.Net.HttpWebResponse)httpWebRequest.GetResponse();

System.IO.Stream stream = httpWebResponse.GetResponseStream();
 byte[] imageData  = ConverToByteArray(stream, 32768);

I want to take a screenshot without using thirdparty app.

Ah. So you want to convert HTML to pixels? :-)

How about this code?
