THPDFBarcodeScanSymbol
Unit: HPDFBarcodeRecognitionScan
THPDFBarcodeScanSymbol= record
Barcode: THPDFBarcodeDecoderResult;
Corners: THPDFBarcodeQuadrilateral;
HasPerspectiveGeometry: Boolean;
Diagnostic: AnsiString;
end;Carries an ordinary decoded barcode with four raster-space corners plus its recognition diagnostic
Verified Data Matrix projective geometry sets HasPerspectiveGeometry; other symbols expose the corners of their axis-aligned bounds
Data Matrix corners follow the detected hull clockwise from an unspecified starting corner; orientation measures the canonical top edge clockwise from the positive raster x axis
