THPDFPageCyclePolicy Type

Controls how page composition maps overlay and underlay positions onto source pages when the target range runs longer than the source

Declaration

THPDFPageCyclePolicy= (pcpStop, pcpRepeat, pcpClamp,
    pcpReverse);

HPDFDoc

Value	Meaning
`pcpStop`	Positions beyond the last source page resolve to no page, so composition comes to a stop for that role
`pcpRepeat`	Positions wrap round with a modulo so that the source pages cycle from the beginning again
`pcpClamp`	Positions beyond the last source page go on resolving to that last source page
`pcpReverse`	Positions ping-pong back and forth across the source pages rather than jumping back to the first page

ComposeLoadedPageRanges takes two values of this type, OverlayCyclePolicy and UnderlayCyclePolicy, applying them independently
A single-page source resolves every position to that one page under pcpClamp and pcpReverse
Only pcpStop leaves target pages with no overlay or underlay content once the source pages run out
