_(This page applies only to the 1.x branch of SVGFig.)_
Line draws a line between two points, but this line is mutable by coordinate transformations. If the coordinates curve, the line will curve.
- Line(x1, y1, x2, y2, arrow_start, arrow_end, attribute=value)*
| x1, y1 | _*required*_ | the starting point | ||||
| x2, y2 | _*required*_ | the ending point | ||||
| arrow_start | default=None | if an identifier string/Unicode, draw a new arrow object at the beginning of the line; if a marker, draw that marker instead | ||||
| arrow_end | default=None | same for the end of the line | ||||
| attribute=value pairs | _keyword list_ | SVG attributes |
To add arrows to the ends of the line, you need to supply a _new_ identifier. If the identifier references another object (SVG `id` attribute), the renderer will attempt to place that object instead (if it's a marker).
Adding an arrow changes the structure of the output SVG.
Line has an *SVG* method, as described in [GeneralPrimitive General features for all primitives].
Line has a *Path* method, as described in [GeneralPrimitive General features for all primitives].
Arrows are ignored by the Path method.
Line has the same defaults as [ClassCurve Curve]. Defaults are described in [GeneralPrimitive General features for all primitives].
| random_sampling | True | if False, bisect with a point exactly halfway between pairs of points; if True, randomly choose a point between 30% and 70% | ||||
| recursion_limit | 15 | number of subdivisions before giving up; if 15, sampling algorithm can visit _at most_ 2^15^ points | ||||
| linearity_limit | 0.05 | maximum deviation (in SVG units) from a straight line | ||||
| discontinuity_limit | 5 | minimum deviation (in SVG units) between points that is considered continuous |
