converts a css matrix string into a mat4 array
npm install css-to-mat4
#### deprecated in favour of mat4-css-parse
Converts a matrix string like "matrix(1, 0, 0, 1, 0, 0)" or "matrix3d(...)" into a 4x4 matrix (flat array).
Simple example:
``js
var parse = require('css-to-mat4')
var str = 'matrix(0, 0, 1, 0, 0, 1)'
var mat = parse(str)
console.log(mat.length) // -> 16
console.log(mat[4] === 1) // -> true
`
Letting the browser compute a matrix from a list of CSS transforms:
`js
var style = require('dom-css')
var parse = require('css-to-mat4')
var getPrefix = require('prefix-style')
var prefix = getPrefix('transform')
if (prefix) { //transforms supported
//apply some transforms with a complex CSS string
style(div, 'transform', 'translateX(20px) rotateX(14deg)')
//get computed style, which will be a flat matrix or matrix3d string
var str = window.getComputedStyle(div)[prefix]
//parse as a 4x4 matrix
var mat = parse(str)
//do something with your matrix
}
`
#### toMat4(str[, out])
Converts the "matrix()" or "matrix3d()" string into a 16-float array representing a 4x4 matrix. 2D matrices will be stored in the upper left of a 4x4 identity matrix.
You can specify an out matrix parameter, otherwise it will create a new 16-length array.
