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);


That's it !

Download Image in Asp.Net
=======================

string ImageFile = Server.MapPath("Hello.jpg");
System.Drawing.Image objImage = System.Drawing.Bitmap.FromFile(ImageFile);
Response.Clear();
Response.ClearContent();
Response.ContentType = "images/jpeg";
Response.AddHeader("Content-Disposition", "attachment; filename=Image.jpg;");

MemoryStream objMem = new MemoryStream();
objImage.Save(objMem, ImageFormat.Jpeg);
objMem.WriteTo(Response.OutputStream);
//objImage.Save(Response.OutputStream, ImageFormat.Jpeg);
Response.End();

Resize Image With Perfect Ratio with [Height x Width] in Asp.Net

Use Namespace
================
using System;
using System.Data;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.HtmlControls;
using System.IO;
using System.Drawing;
using System.Drawing.Imaging;
using System.Runtime.InteropServices;

Code Behind
============

System.Drawing.Image img;
img = System.Drawing.Image.FromFile(cStrTextFileName);

Bitmap bmp = new System.Drawing.Bitmap(img);

System.Drawing.Image.GetThumbnailImageAbort imgCallBack = new System.Drawing.Image.GetThumbnailImageAbort(CallBackMethod);

//System.Drawing.Bitmap bmpThumbnail = ((Bitmap)bmp.GetThumbnailImage(62, 48, imgCallBack, IntPtr.Zero));

/******************/
int[] HWRation = ResizeImageWithRatio(img, 120, 60);
/******************/

System.Drawing.Bitmap bmpThumbnail = ((Bitmap)bmp.GetThumbnailImage(HWRation[0], HWRation[1], imgCallBack, IntPtr.Zero));

//System.Drawing.Bitmap bmpThumbnail = ((Bitmap)bmp.GetThumbnailImage(120, 60, imgCallBack, IntPtr.Zero));
bmpThumbnail.SetResolution(img.HorizontalResolution, img.VerticalResolution);
img.Dispose();

bmpThumbnail.Save(Server.MapPath("images/logo/") + Session["userid"].ToString() + strExtension);

imgImage.Src = "images/logo/" + Session["userid"].ToString() + strExtension;

// Upload New File..
// fileImage.PostedFile.SaveAs(MapPath("logo/") + Session["userid"].ToString() + strExtension);

Image Resize Function
=====================
int[] ResizeImageWithRatio(System.Drawing.Image img, int MaxWidth, int MaxHeight)
{
int[] newHeightWidth = new int[2];

if (img.Width > MaxWidth || img.Height > MaxHeight)
{
double widthRatio = (double)img.Width / (double)MaxWidth;
double heightRatio = (double)img.Height / (double)MaxHeight;
double ratio = Math.Max(widthRatio, heightRatio);
int newWidth = (int)(img.Width / ratio);
int newHeight = (int)(img.Height / ratio);

newHeightWidth[0] = newWidth;
newHeightWidth[1] = newHeight;

}
else
{
newHeightWidth[0] = img.Width;
newHeightWidth[1] = img.Height;
}
return newHeightWidth;
}
