PDEImageJPXAcquireColorSpace

Header: PERProcs.h:2796

Description

Acquires the PDEColorSpace associated with the JPX encoded image, if one exists. If a PDF color space has not been associated with the JPX encoded image, 0 will be returned. This object is acquired and must be released using PDERelease() when it is no longer in use.
