How to create Image reflection in Asp.Net

How to create Image reflection in Asp.Net
=======================================

Method :
---------

public Image DrawReflection(Image _Image, Color _BackgroundColor, int _Reflectivity)
{
// Calculate the size of the new image
int height = (int)(_Image.Height + (_Image.Height * ((float)_Reflectivity / 255)));
Bitmap newImage = new Bitmap(_Image.Width, height, PixelFormat.Format24bppRgb);
newImage.SetResolution(_Image.HorizontalResolution, _Image.VerticalResolution);

using (Graphics graphics = Graphics.FromImage(newImage))
{
// Initialize main graphics buffer
graphics.Clear(_BackgroundColor);
graphics.DrawImage(_Image, new Point(0, 0));
graphics.InterpolationMode = InterpolationMode.HighQualityBicubic;
Rectangle destinationRectangle = new Rectangle(0, _Image.Size.Height, _Image.Size.Width, _Image.Size.Height);

// Prepare the reflected image
int reflectionHeight = (_Image.Height * _Reflectivity) / 255;
Image reflectedImage = new Bitmap(_Image.Width, reflectionHeight);

// Draw just the reflection on a second graphics buffer
using (Graphics gReflection = Graphics.FromImage(reflectedImage))
{
gReflection.DrawImage(_Image, new Rectangle(0, 0, reflectedImage.Width, reflectedImage.Height),
0, _Image.Height - reflectedImage.Height, reflectedImage.Width, reflectedImage.Height, GraphicsUnit.Pixel);
}
reflectedImage.RotateFlip(RotateFlipType.RotateNoneFlipY);
Rectangle imageRectangle = new Rectangle(destinationRectangle.X, destinationRectangle.Y,
destinationRectangle.Width, (destinationRectangle.Height * _Reflectivity) / 255);

// Draw the image on the original graphics
graphics.DrawImage(reflectedImage, imageRectangle);

// Finish the reflection using a gradiend brush
LinearGradientBrush brush = new LinearGradientBrush(imageRectangle,
Color.FromArgb(255 - _Reflectivity, _BackgroundColor),
_BackgroundColor, 90, false);
graphics.FillRectangle(brush, imageRectangle);
}

return newImage;
}

How to Use It (Testing)
-----------------------------

Response.ContentType = "image/jpeg";

Image objImage = Image.FromFile(Server.MapPath("Image.jpg"));

Image objImage2 = this.DrawReflection(objImage, Color.White, 80);

objImage2.Save(Response.OutputStream, ImageFormat.Jpeg);
