Values
| Value | Meaning |
|---|---|
ocmpAnyOn | /AnyOn: the membership is visible when at least one listed OCG is ON; this is the PDF default should /P be absent |
ocmpAllOn | /AllOn: visible only when all of the listed OCGs are ON |
ocmpAnyOff | /AnyOff: visible when at least one of the listed OCGs is OFF |
ocmpAllOff | /AllOff: visible only when all of the listed OCGs are OFF |
Usage notes
- Pass a value of this type to THotPDF.AddLoadedOptionalContentMembership along with the list of OCG object numbers; the policy name (AnyOn, AllOn, AnyOff, AllOff) is written verbatim to /P
- ocmpAnyOn is written out explicitly even though it is the spec default, so the produced file states its intent
- The policy combines with the /VE visibility expression entry should both be present in the membership dictionary
