Description
name
Required. The ColdFusion image on which this operation is performed.

Usage

EXIF is a standard for storing interchange information in image files, especially those using JPEG compression. Most digital cameras use the EXIF format. EXIF metadata includes information pertaining to the creation of the image, such as the creation date, the software used to create the image, the aperture, the make and model, and the exposure of the image.
The result of the ImageGetEXIFMetadata function is cached in the ColdFusion image to optimize performance. The ImageGetEXIFMetadata function applies only to JPEG images. If you try to retrieve metadata for Base64, BLOB, or other types of images, ColdFusion generates errors.
