simplecv help(DrawingLayer.rectangle)

Posted on 2016年11月8日 by allenmo

Help on method rectangle in module SimpleCV.DrawingLayer:

rectangle(self, topLeft, dimensions, color=(0, 0, 0), width=1, filled=False, alpha=-1) unbound SimpleCV.DrawingLayer.DrawingLayer method
    Draw a rectangle given the topLeft the (x,y) coordinate of the top left
    corner and dimensions (w,h) tge width and height

    color - The object's color as a simple CVColor object, if no value  is sepcified
            the default is used.

    alpha - The alpha blending for the object. If this value is -1 then the
            layer default value is used. A value of 255 means opaque, while 0
            means transparent.

    w -     The line width in pixels. This does not work if antialiasing is enabled.

    filled -The rectangle is filled in
(END)
