# `ExGram.Model.MaskPosition`
[🔗](https://github.com/rockneurotiko/ex_gram/blob/0.64.0/lib/ex_gram.ex#L6228)

This object describes the position on faces where a mask should be placed by default.

Check the [documentation of this model on Telegram Bot API](https://core.telegram.org/bots/api#maskposition)

- `point`: The part of the face relative to which the mask should be placed. One of "forehead”, "eyes”, "mouth”, or "chin”.
- `x_shift`: Shift by X-axis measured in widths of the mask scaled to the face size, from left to right. For example, choosing -1.0 will place mask just to the left of the default mask position.
- `y_shift`: Shift by Y-axis measured in heights of the mask scaled to the face size, from top to bottom. For example, 1.0 will place the mask just below the default mask position.
- `scale`: Mask scaling coefficient. For example, 2.0 means double size.
