What is the embedded metadata attribute and value to identify if a transparent background exists within a digital image by metadata alone? There is a need to be able to know they are present via metadata, look it up on Bridge via metadata and report on it in bulk for hundreds of thousands of images at a time. Not by visually checking each image which is unrealistic in volume. If it does not exist today, can we have a means of identifying Transparent backgrounds within embedded metadata that can be checked (in bulk) for many images? I did find the ability to identify a clipping path in embedded metadata in bulk without ever visually checking an image (ClippingPathName : Path1), so please make it easier to identify images with a transparent background without opening them up and visually checking them for time savings. If this does exist, please share how to identify transparent backgrounds with embedded metadata alone.
