6.6. The canvas line object

In general, a line can consist of any number of segments connected end to end, and each segment can be straight or curved. To create a canvas line object on a canvas C, use:

    id = C.create_line ( x0, y0, x1, y1, ..., xn, yn, option, ... )

The line goes through the series of points (x0, y0), (x1, y1), … (xn, yn). Options include:

`arrow`	The default is for the line to have no arrowheads. Use `arrow=FIRST` to get an arrowhead at the (`x0`, `y0`) end of the line. Use `arrow=LAST` to get an arrowhead at the far end. Use `arrow=BOTH` for arrowheads at both ends.
`arrowshape`	A tuple `(d1, d2, d3)` that describes the shape of the arrowheads added by the `arrow` option. Default is `(8,10,3)`.
`fill`	The color to use in drawing the line. Default is `fill="black"`.
`smooth`	If true, the line is drawn as a series of parabolic splines fitting the point set. Default is false, which renders the line as a set of straight segments.
`splinesteps`	If the `smooth` option is true, each spline is rendered as a number of straight line segments. The `splinesteps` option specifies the number of segments used to approximate each section of the line; the default is `splinesteps=12`.
`stipple`	To draw a stippled line, set this option to a bitmap that specifies the stippling pattern, such as `stipple="gray25"`. See Section 4.7, “Bitmaps” for the possible values.
`tags`	The tags to be associated with the object, as a sequence of strings. See Section 6.1.4, “Canvas tags”.
`width`	The line's width. Default is 1 pixel. See Section 4.1, “Dimensions” for possible values.
