`pdfCreateBarcodeField`

Create a barcode-bearing widget field — a form field whose

int32_t __stdcall pdfCreateBarcodeField(PPDF IPDF, const char* Name, int32_t Parent, double PosX, double PosY, double Width, double Height, TPDFBarcode* Barcode);

Delphi

function pdfCreateBarcodeField(const IPDF: PPDF; const Name: PAnsiChar; Parent: Integer; PosX, PosY, Width, Height: Double; Barcode: PPDFBarcode): Integer; stdcall;

Purpose. Create a barcode-bearing widget field — a form field whose visible appearance is a QR code rendered from the field's own caption text (the same IBarcode-object-descriptor-bearing field consumed by pdfGetBarcodeDict, Barcodes and Optional-Content (OCG) State).

Description. Only Barcode.CaptionA/CaptionW are consulted (A preferred if both are set; W UTF-8-encoded if only that is set) — every other TPDFBarcode field is ignored, consistent with that struct's deliberately caption-only shape (Barcodes and Optional-Content (OCG) State). Parent is, per the chapter-wide note, silently dropped.

Parameters.

Parameter	Description
`IPDF`	Document handle.
`Name`	Field name.
`Parent`	Accepted but silently dropped.
`PosX`, `PosY`, `Width`, `Height`	Placement box.
`Barcode`	Only `CaptionA`/`CaptionW` are read.

Return value. The new field's handle; 0 if IPDF is invalid.
