Expand description

A parametrized curve that reports its extrema.

Required Methods§

Compute the extrema of the curve.

Only extrema within the interior of the curve count. At most four extrema can be reported, which is sufficient for cubic Béziers.

The extrema should be reported in increasing parameter order.

Provided Methods§

Return parameter ranges, each of which is monotonic within the range.

The smallest rectangle that encloses the curve in the range (0..1).
