Cropping TilingSprite Texture

Hi all! Here is the example I have

https://labs.phaser.io/edit.html?src=src\game%20objects\tile%20sprite\Example%20-%20Canvas.js

Put the code:

var config = {
    parent: 'phaser-example',
    scene: {
        preload: preload,
        create: create,
        update: update
    }
};

var image1;
var game = new Phaser.Game(config);
var iter = 0;

function preload () {
  this.load.image('image1', 'https://devplatform.ml/local/phaser3/2t6iu-IvankaTrump.png');
}

function create () {
  image1 = this.add.tileSprite(400, 300, 800, 192, 'image1');
}

function update () {
  image1.tilePositionX = Math.cos(-iter) * 400;
  iter += 0.01;
}

As you can see the girl face have some unused space on left and right sides so the tilingsprite have gaps. Is there a way to crop the TilingSprite texture to remove this gaps between girl faces ? Thanks in advance

Probably there is, but it would be easier to just edit the image.
