Question

I have a method as shown below to save image as jpeg.
I want to save all the pictures with the same height and width without it getting distorted.

How can I do that?
Please help

public void SaveFileOnDisk(MemoryStream ms, string FileName)
{
    try
    {
        string appPath = HttpContext.Current.Request.ApplicationPath;
        string physicalPath = HttpContext.Current.Request.MapPath(appPath);
        string strpath = physicalPath + "\\Images";
        string WorkingDirectory = strpath;


        System.Drawing.Image imgSave = System.Drawing.Image.FromStream(ms);
        Bitmap bmSave = new Bitmap(imgSave);
        Bitmap bmTemp = new Bitmap(bmSave);

        Graphics grSave = Graphics.FromImage(bmTemp);
        grSave.DrawImage(imgSave, 0, 0, imgSave.Width, imgSave.Height);

        bmTemp.Save(WorkingDirectory + "\\" + FileName + ".jpg");


        imgSave.Dispose();
        bmSave.Dispose();
        bmTemp.Dispose();
        grSave.Dispose();
    }
    catch (Exception ex)
    {
        //lblMsg.Text = "Please try again later.";
    }

}

Resize the Image and Save it

Private void ResizeImage(Image img, double maxWidth, double maxHeight)
{
    double srcWidth = img.Source.Width;
    double srcHeight = img.Source.Height;

    double resizeWidth = srcWidth;
    double resizeHeight = srcHeight;

    double aspect = resizeWidth / resizeHeight;

    if (resizeWidth > maxWidth)
    {
        resizeWidth = maxWidth;
        resizeHeight = resizeWidth / aspect;
    }
    if (resizeHeight > maxHeight)
    {
        aspect = resizeWidth / resizeHeight;
        resizeHeight = maxHeight;
        resizeWidth = resizeHeight * aspect;
    }

    img.Width = resizeWidth;
    img.Height = resizeHeight;
}

You could use this code to Resize the image to the required Dimention Before saving it
