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?
Instances
| Fractional n => Default (AdjustOpts n) Source # | |
Defined in Diagrams.Parametric.Adjust Methods def :: AdjustOpts n # | |
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 |
Instances
| Fractional n => Default (AdjustMethod n) Source # | |
Defined in Diagrams.Parametric.Adjust Methods def :: AdjustMethod n # | |
data AdjustSide Source #
Which side of a segment, trail, or path should be adjusted?
