Description
Creates a TRectF rectangle having floating-point coordinates.
Use Create to construct and initialize a new TRectF rectangle object having Single coordinates:
- Origin and P1 represent the upper-left corner of the rectangle as the TPointF type point.
- P2 represents the lower-right corner of the rectangle as the TPointF type point.
- Top, Bottom, Right, and Left are Single vertical or horizontal coordinates of the upper, lower, right, and left sides of the rectangle, respectively.
- Width and Height are Single width and height of the rectangle, respectively.
- R is the rectangle with coordinates specified using the TRectF (or TRect) type.
- Normalize specifies to create a normalized rectangle.
- Note:
Create(const Origin: TPointF)creates an empty rectangle at the given Origin.
