Installation

To install this library use your favorite package manager. No additional steps are required to start using the library.

npm install @n7e/transpose

This library is implemented in TypeScript but can be used with JavaScript without any additional steps.

Transpose

Let's start with an example and transpose the value 50 from one range to another.

import { transpose } from "@n7e/transpose";

transpose(50).from([0, 100]).to([0, 10]); // -> 5
transpose(50).from([0, 100]).to([-5, 5]); // -> 0
transpose(50).from([0, 100]).to([-12, -2]); // -> -7

Value Proxy

To reuse the same value for different transpositions the transpose() function produces a value proxy object that can be reused.

import { transpose } from "@n7e/transpose";

const valueProxy = transpose(50);

valueProxy.from([0, 100]).to([0, 10]); // -> 5
valueProxy.from([0, 100]).to([-5, 5]); // -> 0

Range Proxy

To reuse the same value and origin range for different transpositions the value proxy object produces a range proxy object that can be reused.

import { transpose } from "@n7e/transpose";

const rangeProxy = transpose(50).from([0, 100]);

rangeProxy.to([0, 10]); // -> 5
rangeProxy.to([-5, 5]); // -> 0
