I am looking for lightweight image processing tool that will resize images to JPEG

  • 0

I am looking for lightweight image processing tool that will resize images to JPEG in YCbCr = 4:4:4, that is, no chromatic subsampling. I am using this to generate square thumbnails.

I need 4:4:4 because I am not sure about the quality of 4.2.2 or 4.1.1 as they will have greater amount of artifacts, which will affect the quality of my thumbnails.

It will be run from a web server (ASP.Net MVC 3). Command-line tool, standalone application and libraries are all acceptable since it will run in separate processes anyway.

Anything out there except ImageMagick? I think it is too bulky.

Thanks a lot for answering.

    Windows Imaging Component allows you to choose your own JPEG chroma subsampling option. See Encoder Options: JPEG Codec specific options: JpegYCrCbSubsampling

    This is a very heavy-handed approach and requires a somewhat difficult learning curve. You may want to look for other options before delving into WIC.
