THPDFPage

Draws a rectangle.

Delphi 語法：

procedure Rectangle ( X, Y, Width, Height: Single );

C++ 語法：

void __fastcall Rectangle ( float X, float Y, float Width, float Height );

說明

使用 Rectangle 繪製 rectangle。請指定 rectangle 的 coordinates 與 size。Coordinates 會以 point（X, Y）定義 upper left corner，並指定 width 與 height

To fill a rectangular region use Fill. To outline a rectangular region without filling it, use Stroke. To draw a rectangle with rounded corners, use RoundRect.
