pdfAddRichMediaAsset

BOOL32 __stdcall pdfAddRichMediaAssetA(PPDF IPDF, uint32_t Annot, const char* FileName, int32_t AType);

function pdfAddRichMediaAssetA(const IPDF: PPDF; Annot: Cardinal; const FileName: PAnsiChar; AType: Integer): LongBool; stdcall;

Purpose. Add an embedded asset (e.g. a 3D model, image, or other resource) to an already-created /RichMedia annotation (3D Annotation Extras, DPart Structure, Article Threads, and Buttons's pdfCreate3DAnnot-adjacent family) — this is the incremental "add-another-asset" call, distinct from pdfRichMediaAnnot (V03), which creates the annotation with its *first* asset already attached.

Description. Reads the whole file into memory and calls AddRichMediaAssetH(Annot, ExtractFileName(fn), data) — the asset's name inside the RichMedia content is always derived from the file's own base name (not independently settable). AType is accepted by the ABI but this chapter did not find it consulted — the asset's declared MIME/subtype in the RichMedia content dictionary appears to be inferred elsewhere (e.g. from the file extension) rather than from this explicit parameter.

Parameters.

Return value. True on success; False if the file doesn't exist.
