Answer 1

Last day I found imageresizer and its great. and good API. Works Great. Downloaded from Visual studio 2010 Extension Manager: http://nuget.org/.

Easy Steps to download API in VS-2010:

1). Install Extension http://nuget.org/.



3). Find and Install ImageResizing

4).Then Code: (I m using here cropping. you can use any) Documentation on imageresizing.net

string uploadFolder = Server.MapPath(Request.ApplicationPath + "images/");
FileUpload1.SaveAs(uploadFolder + FileUpload1.FileName);


//The resizing settings can specify any of 30 commands.. See http://imageresizing.net for details.
ResizeSettings resizeCropSettings = new ResizeSettings("width=200&height=200&format=jpg&crop=auto");

//Generate a filename (GUIDs are safest).
string fileName = Path.Combine(uploadFolder, System.Guid.NewGuid().ToString());

//Let the image builder add the correct extension based on the output file type (which may differ).
fileName = ImageBuilder.Current.Build(uploadFolder + FileUpload1.FileName, fileName, resizeCropSettings, false, true);

Try!!! its very awsumm and easy to use. thanks.
