pdfCreate3DGotoViewAction

int32_t __stdcall pdfCreate3DGotoViewAction(PPDF IPDF, uint32_t Base3DAnnot, void* IView, int32_t Named);

function pdfCreate3DGotoViewAction(const IPDF: PPDF; Base3DAnnot: Cardinal; const IView: Pointer; Named: Integer): Integer; stdcall;

Purpose. Create a /GoTo3DView action jumping to a specific view on a 3D annotation — e.g. attached to a bookmark, link, or button to switch camera views on click.

Description. Decodes IView to (regIdx, viewIdx) and binds the target view (viewIdx) to Base3DAnnot in the action — per an inline source comment, "the view index is bound to the target 3D annotation (by its NM) in the action," i.e. the annotation identity is carried by name reference in the emitted action, not by the decoded regIdx (which is used only internally to validate/locate the view during this call). Named is accepted by the ABI but never passed through to Create3DGotoViewActionH — whatever behavior it would select (e.g. referencing the view by its /IN name string vs. an indirect object reference) has no effect regardless of value.

Parameters.

Return value. The new action's handle; 0 if IView is nil or doesn't decode to a valid view, or IPDF is invalid.
