2d-css-matrix-parse

Converts css transform matrix to an 2D array of 6 values(3x3 matrix).

Function parse

The parse function takes a matrix string representation like matrix(1.1, 0, 0, 1.1, 0, 0) and parse it to an array of floats.

var matrixTransform = require('./index.js');

var matrix = "matrix(1.1, 0, 0, 1.1, 0, 0)";

matrixTransform.parse(matrix);
// -> [1.1, 0, 0, 1.1, 0, 0]

Function fromElement

The fromElement function tries to help you to get the transform string matrix representation and let you pass instead of the string the HTML element itself.

var matrixTransform = require('./index.js');

var element = document.createElement('div');
element.style.transform = "scale(1.5)";
document.body.appendChild(element);

matrixTransform.fromElement(element);
// -> [1.5,0,0,1.5,0,0]

Important Note:

Doesn't matter if the transform is not formatted as a matrix, in the above example we are setting to element the value scale instead of the current matrix.

Usage

matrixTransform.parse(string)

It takes a string matrix representation and gives you an array.

matrixTransform.fromElement(HtmlElement)

It takes an Html Element and gives you an array with the element transformation.
