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