THPDFPageCyclePolicy Type

Controls how page composition maps overlay and underlay positions onto source pages when the target range is 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 stops for that role
`pcpRepeat`	Positions wrap around with a modulo so the source pages cycle from the beginning again
`pcpClamp`	Positions beyond the last source page keep resolving to that last source page
`pcpReverse`	Positions ping-pong back and forth across the source pages instead of jumping back to the first page

ComposeLoadedPageRanges takes two values of this type, OverlayCyclePolicy and UnderlayCyclePolicy, and applies them independently
A single-page source resolves every position to that page under pcpClamp and pcpReverse
Only pcpStop leaves target pages without overlay or underlay content once the source pages run out
