How to resize an image in byte[] ?

 This code creates a byte[] that contains an image into a byte[] that contains an image of a different size.  At this point it does create a byte array of the proper size, and it inserts a new row into the table.   I created the code that reads it back out of the table and displays it on the ASP.NET page.  The image displays as it should, which verifies that it is properly encoded in the new byte array.


 #region Create Thumbnail
    // Create a thumbnail in byte array format from the image encoded in the passed byte array.  
    // (RESIZE an image in a byte[] variable.)  
    public static byte[] CreateThumbnail(byte[] PassedImage, int LargestSide, int Height, int Width)
    {
        byte[] ReturnedThumbnail;

        using (System.IO.MemoryStream StartMemoryStream = new System.IO.MemoryStream(), NewMemoryStream = new System.IO.MemoryStream())
        {
            // write the string to the stream  
            StartMemoryStream.Write(PassedImage, 0, PassedImage.Length);

            // create the start Bitmap from the MemoryStream that contains the image  
            System.Drawing.Bitmap startBitmap = new System.Drawing.Bitmap(StartMemoryStream);

            // set thumbnail height and width proportional to the original image.  
            int newHeight;
            int newWidth;
            double HW_ratio;
            if (startBitmap.Height > startBitmap.Width)
            {
                newHeight = LargestSide;
                HW_ratio = (double)((double)LargestSide / (double)startBitmap.Height);
                newWidth = (int)(HW_ratio * (double)startBitmap.Width);
            }
            else
            {
                newWidth = LargestSide;
                HW_ratio = (double)((double)LargestSide / (double)startBitmap.Width);
                newHeight = (int)(HW_ratio * (double)startBitmap.Height);
            }
            newHeight = Height;
            newWidth = Width;
            // create a new Bitmap with dimensions for the thumbnail.  
            System.Drawing.Bitmap newBitmap = new System.Drawing.Bitmap(newWidth, newHeight);

            // Copy the image from the START Bitmap into the NEW Bitmap.  
            // This will create a thumnail size of the same image.  
            newBitmap = ResizeImage(startBitmap, newWidth, newHeight);

            // Save this image to the specified stream in the specified format.  
            newBitmap.Save(NewMemoryStream, System.Drawing.Imaging.ImageFormat.Jpeg);

            // Fill the byte[] for the thumbnail from the new MemoryStream.  
            ReturnedThumbnail = NewMemoryStream.ToArray();
        }
        // return the resized image as a string of bytes.  
        return ReturnedThumbnail;
    }

    // Resize a Bitmap  
    private static System.Drawing.Bitmap ResizeImage(System.Drawing.Bitmap image, int width, int height)
    {
        System.Drawing.Bitmap resizedImage = new System.Drawing.Bitmap(width, height);
        using (System.Drawing.Graphics gfx = System.Drawing.Graphics.FromImage(resizedImage))
        {
            gfx.DrawImage(image, new System.Drawing.Rectangle(0, 0, width, height),
                new System.Drawing.Rectangle(0, 0, image.Width, image.Height), System.Drawing.GraphicsUnit.Pixel);
        }
        return resizedImage;
    }

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

    public System.Drawing.Image byteArrayToImage(byte[] byteArrayIn)
    {
        MemoryStream ms = new MemoryStream(byteArrayIn);
        System.Drawing.Image returnImage = System.Drawing.Image.FromStream(ms);
        return returnImage;
    }

    #endregion



User above code like this :

    System.Drawing.Image returnImage;
    byte[] byteArrayIn;
    MemoryStream ms;

    //Get Bytes from Requested file
    byte[] buffer = new byte[uploads.ContentLength];
    uploads.InputStream.Read(buffer, 0, uploads.ContentLength);

    if ((uploads.ContentLength / 1000) > 1000)
    {
        //Create image from Bytes array
        System.Drawing.Image img = byteArrayToImage(buffer);

        int height = Convert.ToInt32(Convert.ToDouble(img.Height) * .7);
        int width = Convert.ToInt32(Convert.ToDouble(img.Width) * .7);

        //Resize Image - ORIGINAL
        byteArrayIn = CreateThumbnail(buffer, 10000, height, width);
        //byteArrayIn = CreateThumbnail(buffer, 10000, 550, 700);
        ms = new MemoryStream(byteArrayIn);
        returnImage = System.Drawing.Image.FromStream(ms);
        returnImage.Save(path_ORIGINAL);
    }
    else
    {
        uploads.SaveAs(path_ORIGINAL);
    }

    //Resize Image - Create Thumbnail
    byteArrayIn = CreateThumbnail(buffer, 100, 105, 145);
    ms = new MemoryStream(byteArrayIn);
    returnImage = System.Drawing.Image.FromStream(ms);
    returnImage.Save(path_Thumbnail);

How to create a countdown timer in jquery

Create a countdown timer in jQuery First we need to include the jQuery library file to the HTML page to perform this task. To do that we need to understand that what exactly a jQuery library fie is ? JQuery library file is the library of JavaScript, which means this file contains the predefined functions of jQuery. We just need to call these functions to perform the task. jQuery functions reduces the lines of code and makes our task easy. As this jQuery library file contains the javascript functions so we need to call the function within <script> </script> tag. Now after including the file, we need to define a variable which will store that for how long you want the timer on the page(c=60) and now the time you set needs to be changed in hours , minutes and seconds using the code “ var hours = parseInt( time / 3600 ) % ;var minutes = parseInt( time / 60 ) % 60; var seconds = time % 60;” Now we need to put the condition if timer got finished (if (t
