scaleX :: ScalingContext ux uy u -> ux -> uSource
scaleY :: ScalingContext ux uy u -> uy -> uSource
scalePt :: ScalingContext ux uy u -> ux -> uy -> Point2 uSource
scaleVec :: ScalingContext ux uy u -> ux -> uy -> Vec2 uSource
unitX :: Num ux => ScalingContext ux uy u -> uSource
unitY :: Num uy => ScalingContext ux uy u -> uSource
uniformScaling :: Num u => u -> ScalingContext u u uSource
Build a ScalingContext where both X and Y are scaled by the same uniform step.
The dimensions (types) of the ScalingContext are unified - the output type and the input types are all the same.
coordinateScaling :: Num u => u -> u -> ScalingContext Int Int uSource
Build a ScalingContext for scaling Int coordinates.
The scaling factors in X and Y can be different sizes.
