Unit: HPDFDataMatrixGeometry

THPDFBarcodeQuadrilateral= array[0..3] of THPDFBarcodePoint;

Represent four consecutive corners of a convex raster-space quadrilateral

Detected corners follow the hull clockwise with an unspecified starting corner; sampling expects consecutive convex corners

The Data Matrix decoder tests rotations and mirrors to find the canonical symbol orientation
