rasExecBookmark

TUpdBmkAction __stdcall rasExecAction(IPGC* CachePtr, void* Ctx);
TUpdBmkAction __stdcall rasExecBookmark(IPGC CachePtr, uint32_t Handle, int32_t* NewX, int32_t* NewY, float* NewZoom, TPDFPageScale* NewPageScale, void* Action);

function rasExecAction(var CachePtr: IPGC; Ctx: Pointer): TUpdBmkAction; stdcall;
function rasExecBookmark(CachePtr: IPGC; Handle: Cardinal; var NewX, NewY: Integer; var NewZoom: Single; var NewPageScale: TPDFPageScale; Action: Pointer): TUpdBmkAction; stdcall;

Purpose. Nominally: execute a PDF action (rasExecAction) or navigate to a bookmark's destination (rasExecBookmark), reporting the resulting viewport position/zoom to scroll to.

Description — both confirmed complete stubs. rasExecAction is Result := TUpdBmkAction(0) — CachePtr/Ctx never read. rasExecBookmark is identically Result := TUpdBmkAction(0) — Handle/Action never read, and none of NewX/NewY/NewZoom/ NewPageScale is ever written, the same class of dead output as rasSelectAnnotOrField's equivalent parameters above. There is no working action-execution or bookmark-navigation entry point anywhere in this ras* viewer surface — a host implementing "click a bookmark, scroll to it" must resolve the destination itself via the document-level bookmark/action APIs (Actions & Named Destinations/E09, Bookmarks and Outlines) and drive rasSetCurrPage/rasZoom/rasScroll (Page Navigation, Layout, and Geometry/E04) directly.

Parameters.

Return value. Always TUpdBmkAction(0).
