ClearDisplayListCache

Rendering

Description

Drops recorded display lists and resets reuse, pressure and contention counters

Syntax

Delphi

Function TPDFlib.ClearDisplayListCache: Integer;

DLL

int DLClearDisplayListCache(int InstanceID);

ActiveX

Function PDFlib::ClearDisplayListCache() As Long

Return values

1The cache was cleared

Remarks

The next render after a clear re-parses each content stream and re-records it

A list currently being captured or replayed is retired immediately and freed when its active renderer releases it, preventing use-after-free during asynchronous rendering
