Description
Defines a rectangle with coordinates in logical units.
TRectD represents the location and dimensions of a rectangle. The coordinates are specified as either four separate Double floating-point coordinates representing the left, top, right, and bottom sides, or as two points representing the locations of the upper-left and lower-right corners.
Typically, TRectD values representing location and dimensions are measured in density-independent pixels (DP) (in logical units). The origin of the coordinate system is in the upper-left corner of a container. The container can be the screen (screen coordinates) or a control's client area (client coordinates).
