### Attributes:
| Name | Type | Required | Description |
|----------|---------------|----------|-------------|
2019-12-27 17:48:04 +01:00
|n|[int](../types/int.md) | Yes|Part of the face, relative to which the mask should be placed|
|x|[double](../types/double.md) | Yes|Shift by X-axis measured in widths of the mask scaled to the face size, from left to right. (For example, -1.0 will place the mask just to the left of the default mask position)|
|y|[double](../types/double.md) | Yes|Shift by Y-axis measured in widths of the mask scaled to the face size, from left to right. (For example, -1.0 will place the mask just to the left of the default mask position)|
|zoom|[double](../types/double.md) | Yes|Mask scaling coefficient. (For example, 2.0 means a doubled size)|

### Type: [MaskCoords](../types/MaskCoords.md)
### Example:
```php
$maskCoords = ['_' => 'maskCoords', 'n' => int, 'x' => double, 'y' => double, 'zoom' => double];
```
Or, if you're into Lua:
```lua
maskCoords={_='maskCoords', n=int, x=double, y=double, zoom=double}
```
