# MLImageSizeConstraintType

The modes that determine how the model defines a feature’s image size constraint.

```
enum MLImageSizeConstraintType
```

## Topics

### Constraint types

[`MLImageSizeConstraintType.range`](/documentation/CoreML/MLImageSizeConstraintType/range)

The image feature accepts image sizes defined by a range of widths and a range of heights.

[`MLImageSizeConstraintType.enumerated`](/documentation/CoreML/MLImageSizeConstraintType/enumerated)

The image feature accepts image sizes listed in an array.

[`MLImageSizeConstraintType.unspecified`](/documentation/CoreML/MLImageSizeConstraintType/unspecified)

The image size constraint is not configured and should be ignored.

### Creating a constraint type

[`init(rawValue:)`](/documentation/CoreML/MLImageSizeConstraintType/init(rawValue:))
