pdfInsertBarcode

int32_t __stdcall pdfInsertBarcode(PPDF IPDF, double PosX, double PosY, double Width, double Height, TCellAlign HAlign, TCellAlign VAlign, TPDFBarcode2* Barcode);

function pdfInsertBarcode(const IPDF: PPDF; PosX, PosY, Width, Height: Double; HAlign, VAlign: TCellAlign; var Barcode: TPDFBarcode2): Integer; stdcall;

Purpose. Draw one of 4 built-in 2D-barcode symbologies onto the current page at the given position/box, aligned within that box.

Description. Dispatches on Barcode.BarcodeType: 0=QR Code (DrawQRBarcode, honoring ECLevel/Version/Mask/QuietZone), 1=Data Matrix (DrawDataMatrixBarcode — note this symbology has no error-correction-level or version concept of its own, so ECLevel/ Version/Mask are silently unused for this type), 2=PDF417 (DrawPDF417Barcode — reinterprets Version as the column count, defaulting to 6 if <= 0, and clamps ECLevel into 0..8 as PDF417's own security-level range rather than QR's 4-level scheme), 3=Aztec (DrawAztecBarcode, same as Data Matrix — no ECLevel/Version/Mask effect). Any other BarcodeType value fails outright. In all four cases, Barcode.Text is required (encoded as raw ANSI/UTF-8 bytes — there is no W/wide-string entry point for barcode text), and the box is laid out at PosX/PosY/Width/Height with HAlign/VAlign cell alignment within that box.

Parameters.

Return value. 1 on success; 0 if IPDF is invalid, BarcodeType is not 0..3, or the underlying symbol encoder rejected the input (e.g. Text too long/invalid for the chosen symbology and error-correction level).
