I am looking c# code which creates better quality higher resolution thumbnail image.

i am having an image of dimension(600 * 900) and i need to create thumbnail of dimension (100 * 100) with high quality.

Answer 1

Would the code in Image Resizing ( http://www.codeproject.com/KB/GDI-plus/imgresizoutperfgdiplus.aspx licensed under the CodeProject Open License) be something of interest? It implements various resampling filters (Hermite,Lanczos3,CatmullRom,QuadraticBSpline,...)

Answer 2

You can use imagemagick http://www.imagemagick.org/script/index.php. Install it and call from c# using command line.
