Function

Summary

Transforms a distance by the rotation and scale of the inverse of a given transform.

Signature

untransform-distance transform dx dy => x y

Arguments

transform

A transform

dx

A real number

dy

A real number

Values

x

A real number

y

A real number

Description

The untransform-distance function transform the distance ( dx dy ) by the rotation and scale of the effective inverse of transform . The translation in the inverse transform is ignored. The transformed distance ( dx dy ) is returned as two values.
