Diagrams.Parametric.Adjust

Description

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

Synopsis

Documentation

adjust :: (V t ~ v, N t ~ n, DomainBounds t, 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?

Instances

adjMethod :: Lens' (AdjustOpts n) (AdjustMethod n) Source

Which method should be used for adjusting?

adjSide :: Lens' (AdjustOpts n) AdjustSide Source

Which end(s) of the object should be adjusted?

adjEps :: Lens' (AdjustOpts n) n Source

Tolerance to use when doing adjustment.

data AdjustMethod n Source

What method should be used for adjusting a segment, trail, or path?

Constructors

ByParam n

Extend by the given parameter value (use a negative parameter to shrink)

ByAbsolute n

Extend by the given arc length (use a negative length to shrink)

ToAbsolute n

Extend or shrink to the given arc length

data AdjustSide Source

Which side of a segment, trail, or path should be adjusted?

Constructors

Start

Adjust only the beginning

End

Adjust only the end

Both

Adjust both sides equally
