Overview

What is CFX_ImageCR?

CFX_ImageCR is a professional quality custom tag for processing images natively with Macromedia Coldfusion.

CFX_ImageCR loads an image file and saves another after performing the operations it has been directed to. Operations include converting, resizing, cropping and much more. All operations are detailed in the attributes section of this documentation. CFX_ImageCR has been used to process images for online retailers, real estate listings, art galleries, photo albums, uploaded images and many more.

CFX_ImageCR can also be used to retrieve image dimensions efficiently, without loading the entire image, a feature previously available separately in our CFX_ImageXY tag. See the getimageinfo attribute for more information. Other new operating modes include setdefaultsave, getdefaultsave, and getversion.
