Beschreibung

Definiert die Punktkoordinaten in logischen Einheiten.

Der Typ TPointD definiert die Double-Gleitkommakoordinaten X und Y einer Punktposition, deren Ursprung sich in der linken oberen Ecke des Containers befindet. X und Y legen die horizontalen bzw. vertikalen Koordinaten eines Punktes fest. Typischerweise stellen X- und Y-Werte dichteunabhängige Pixel (DP) (logische Einheiten) dar.
