Description
Defines the point coordinates in logical units.
The TPointD type defines the Double floating-point X and Y coordinates of a point location, with the origin in the upper-left corner of the container. X and Y specify the horizontal and vertical coordinates of a point, respectively. Typically, X and Y values represent density-independent pixels (DP) (logical units).
