Composes a single transformation by matrix multiplication.

Type signature

(...matrices: {
    a: number;
    c: number;
    e: number;
    b: number;
    d: number;
    f: number;
}[]) => {
    a: number;
    c: number;
    e: number;
    b: number;
    d: number;
    f: number;
}

Examples

const originX = 5;
const originY = 6;
const angle = Math.PI;

transform(
  translate(originX, originY),
  rotate(angle),
  translate(-originX, -originY),
);
// ⇒ rotate(Math.PI, originX, originY)
