disp_rectangle2 — Displays arbitrarily oriented rectangles.
显示任意角度的长方形
disp_rectangle2( : : WindowHandle, CenterRow, CenterCol, Phi, Length1, Length2 : )
disp_rectangle2 draws one or several arbitrarily oriented rectangles in the output window. A rectangle is described by the center (CenterRow,CenterCol), the orientation Phi (in radians) and half the lengths of the edges Length1 and Length2. The procedures used to control the display of regions (e.g. set_draw, set_gray, set_draw) can also be used with rectangles. Several rectangles can be displayed with one call by using tuple parameters. For the use of colors with several rectangles, see set_color.
主要作用，在输出窗口显示一个或是多个任意角度的长方形，这个长方形的中心点为(CenterRow,CenterCol)，方向为：Phi，长边的一半为：Length1，短边的一半为：Length2
The center must lie within the window boundaries.
