JPXColorSpaceAcquireNext

Header: PERProcs.h:2937

Description

Acquires the next JPX color space defined with the JPX encoded image in the link list, if one exists. This object is acquired and must be released using PDERelease() when it is no longer in use.

Syntax

JPXColorSpace JPXColorSpaceAcquireNext(IN JPXColorSpace jpxColorSpace);

Parameters

jpxColorSpace
IN/OUT A JPX color space object.

Returns

The next JPX color space associated with the JPX encoded image.

JPXColorSpaceGetEnumAttrs

Header: PERProcs.h:2971

Description

Gets the attributes of an enumerated color space. It returns false if the color space is not kJPXCSEnumerated.

Syntax

ASBool JPXColorSpaceGetEnumAttrs(IN JPXColorSpace jpxColorSpace, OUT JPXCSEnumAttrsP jpxCSEnumAttrsP);

Parameters

jpxColorSpace
IN/OUT A JPX color space object.
jpxCSEnumAttrsP
IN/OUT (filled in by the method) Attributes of a JPX enumerated color space.

Returns

true if the JPX color space is kJPXCSEnumerated

JPXColorSpaceGetProfile

Header: PERProcs.h:2988

Description

Gets the color profile of an ICC-based JPX color space. If profile is 0, it returns the length of the profile in bytes; otherwise it returns the number of bytes copied to profile.

profile
IN/OUT (Filled by the method) The profile of the JPX color space.
profileLength
IN/OUT The byte length of the user-supplied profile buffer.
