Runtime genrationn of Good quality Images

With one day effort , i found how to generate quality images dynamicaly

<%@ WebHandler Language="C#" Class="Handler" %>

using System;
using System.Web;
using System.Drawing;
using System.Drawing.Imaging;
using System.Web.SessionState;
using System.IO;
public class Handler : IHttpHandler,IReadOnlySessionState
{

public void ProcessRequest (HttpContext context) {

Image img = new Bitmap(context.Session["ImagePath"].ToString());

Size _newSize = new Size(800, 800);
img = ResizeImage(img, _newSize);
using (MemoryStream stream = new MemoryStream())
{
int quality = 150; //90 is the magic setting - really. It has excellent quality and file size.
System.Drawing.Imaging.EncoderParameters encoderParameters = new System.Drawing.Imaging.EncoderParameters(1);
encoderParameters.Param[0] = new System.Drawing.Imaging.EncoderParameter(System.Drawing.Imaging.Encoder.Quality, (long)quality);



//img.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp);
img.Save(stream, GetEncoderInfo("image/bmp"), encoderParameters);
stream.WriteTo(context.Response.OutputStream);


}
}

private static ImageCodecInfo GetEncoderInfo(String mimeType)
{

int j;

ImageCodecInfo[] encoders;

encoders = ImageCodecInfo.GetImageEncoders();

for (j = 0; j < encoders.Length; ++j)
{

if (encoders[j].MimeType == mimeType)

return encoders[j];

}

return null;

}




private static System.Drawing.Image ResizeImage(System.Drawing.Image original, Size newSize)
{ System.Drawing.Image result = new Bitmap(newSize.Width, newSize.Height);
using(Graphics g = Graphics.FromImage(result))
{ g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;


g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.AntiAlias;

g.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.HighQualityBicubic;

g.CompositingQuality = System.Drawing.Drawing2D.CompositingQuality.HighQuality;

g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.ClearTypeGridFit;

g.DrawImage(original, 0, 0, newSize.Width, newSize.Height); }
return result;}



public bool IsReusable {
get {
return false;
}
}
