Comments:

This is not a compression scheme but rather a saving mode, allowing to save FlashPix images with the same compression as they were loaded. Use this mode to change FlashPix image metadata without changing its pixels.

This compression requires the ImageGear FlashPix Component to be attached. See Attaching Components.
