Description

Tools for adjusting the length of parametric objects such as segments and trails.

Synopsis

Documentation

adjust :: (N t ~ n, Sectionable t, HasArcLength t, Fractional n) => t -> AdjustOpts n -> t Source #

Adjust the length of a parametric object such as a segment or trail. The second parameter is an option record which controls how the adjustment should be performed; see AdjustOpts.

data AdjustOpts n Source #

How should a segment, trail, or path be adjusted?
