Description
Définit les coordonnées du point en unités logiques.
Le type TPointD définit la valeur en virgule flottante à double précision des coordonnées X et Y de l'emplacement d'un point ayant son origine dans le coin supérieur gauche du conteneur. X et Y spécifient respectivement les coordonnées horizontales et verticales d'un point. Typiquement, les valeurs X et Y représentent des pixels indépendants de la densité (DP), en unités logiques.
