    rectangle(img, pt1, pt2, color[, thickness[, lineType[, shift]]]) -> img
    .   @brief Draws a simple, thick, or filled up-right rectangle. 
    	绘制一个简单的、具有厚度的，或者实心的直角矩形
    .   
    .   The function cv::rectangle draws a rectangle outline or a filled rectangle whose two opposite corners
    .   are pt1 and pt2.
    	函数cv :: rectangle绘制一个矩形轮廓或一个填充的矩形，其两个相对角为pt1和pt2。
    .   
    .   @param img Image. 图片
    .   @param pt1 Vertex of the rectangle. 矩形的顶点
    .   @param pt2 Vertex of the rectangle opposite to pt1 . 与pt1相反的矩形的顶点
    .   @param color Rectangle color or brightness (grayscale image). 矩形颜色或亮度（灰度图像）
    .   @param thickness Thickness of lines that make up the rectangle. Negative values, like #FILLED,
    .   mean that the function has to draw a filled rectangle.
    		组成矩形的线的粗细。 负值（如#FILLED）表示该函数必须绘制一个填充的矩形。
    .   @param lineType Type of the line. See #LineTypes 线的类型。 请参阅#LineTypes
    .   @param shift Number of fractional bits in the point coordinates. 点坐标中的小数位数。
