What is ITS?

The Image Transformation Service (ITS) is a unique tool created to take large “mezzanine” images and reduce them to a variety of sizes on the fly.  ITS takes a single image and retrofits it into assorted pages and platforms that require many different image sizes.  And because ITS connects to a CDN, image retrieval is much faster. 

Important notes about ITS

A few things to remember when using ITS:

  • Start with the largest image file size possible.
  • You can choose to resize and retain the original aspect ratio or you can choose to crop your image.
  • Supported output file types are jpg, png, and gif only.
  • You must manually add parameters in the decorator to customize the image returned from ITS.
  • If using the proxy service, images may take a few days to be cached in the CDN.
