Set alpha to specific pixel

Is it possible to set alpha on specific pixel or pixel area in phaser 3?
In Phaser 2 you can use BitmapData which has some functions for it, for excample setPixel(x, y, red, green, blue, alpha, immediate), but in Phaser 3 i didn’t find something.

Phaser 3 has canvas texture, which can paste texture, get/set image data of pixel. Here is a test case, and api.

Thank you!
