    1. Bitmap b = BitmapFactory.decodeByteArray(bitmapProfilePic , 0, bitmapProfilePic .length)  
    2. ivProfilePic.setImageBitmap(Bitmap.createScaledBitmap(b, 120, 120, false));

    Hi hemalatha,
     
    I just tested with Image Control and a sample bitmap image in sample asp.net web application. It is displaying the image of extension .bmp.
     
    I think this is not the problem with Image Control. It is supporting .bmp files.
     
    I am attaching sample for your reference.
     
    Thank you.

    1. Convert Image to Bytes.  
    2.   
    3. public static byte[] ImageToByte2(Image img)  
    4. {  
    5.     byte[] byteArray = new byte[0];  
    6.     using (MemoryStream stream = new MemoryStream())  
    7.     {  
    8.         img.Save(stream, System.Drawing.Imaging.ImageFormat.Png);  
    9.         stream.Close();  
    10.   
    11.         byteArray = stream.ToArray();  
    12.     }  
    13.     return byteArray;  
    14. }  
    15.   
    16. In the code behind use   
    17.   
    18. Convert BMP file to img.  
    19.   
    20. System.Drawing.Image img = null;   
    21. img = System.Drawing.Image.FromFile(Server.MapPath(_ImageUrl));  
    22.   
    23. var imgArr= ImageToByte2(img);  
    24.   
    25. string base64String = Convert.ToBase64String(imgArr= , 0, imgArr= .Length);  
    26. Image1.ImageUrl = "data:image/jpeg;base64," + Convert.ToBase64String(base64String)

    4. Graphics grph = Graphics.FromImage(bitmapimg);  
    5. SolidBrush br = new SolidBrush(Color.Green);  
    6. grph.FillEllipse(br, 4, 4, 110, 110);  
    7. Response.ContentType = "image/gif";  
    8. bitmapimg.Save(Response.OutputStream, ImageFormat.Gif);
