dimension_calculator

If you want to resize an object and know the height or width you would like, the dimension calculator will return the other dimension needed to maintain the original height/width ratio. Supports all object types that have width and height properties.

Install

$ npm install --save dimension_calculator

Usage

The first argument passed in should be an object with either the height or width to which you would like to resize. (ex { width: 40 })

The second argument passed in should be the object you would like to resize. It should have properties height and width. (ex { width: 100, height: 50 })

The dimension calculator will calculate the ratio of the dimensions for the original object and return the other dimension size (in this case height), needed to maintain the original height/width ratio.

const dimensionCalculator = require('dimension_calculator');

// Calculate the dimension needed
dimensionCalculator({ width: 40 }, { width: 100, height: 50 })
=> 20
