Rectjuster

Rectjuster is a tool for scaling rectangles with a given aspect ratio, minimum width, and / or height to fit inside a larger rectangle with a given width and height. It also takes into account the width of the padding on the bottom and right sides of the rectangles.

The result of the adjustment includes the width and height of the scaled rectangles and the number of rows and columns according to which the rectangles are to be arranged inside a larger rectangle. The result of the calculation also includes the actual number of rectangles that fit inside the larger rectangle with the given minimum width and / or height.

Installation

npm install rectjuster
