Line()
语法
Line(x, y, Width, Height [, Color])概要
Draw a line of given dimensions on the current output. The current output is set with StartDrawing().
参数
x, y The origin of the line to draw. Width, Height The dimension of the line to draw. These values include the starting point so a Height of 1 draws a horizontal line while a Height of 0 draws nothing at all. Color (optional) The color to be used for the line. If this parameter is not specified, the default color set with FrontColor() will be used. This color can be in RGB or RGBA format.
返回值
无.
Remarks
To draw a line given the coordinates of the start- and end point, use the LineXY() function.
