# Options

```
struct Options
```

Document capture options.

- <a id="/s:17IDentitySDK_Swift15DocumentCaptureC7OptionsV28lowerWidthThresholdToleranceSfvp"></a>

  <a id="//apple_ref/swift/Property/lowerWidthThresholdTolerance"></a>

  `lowerWidthThresholdTolerance`

  Lower document capture rectangle width threshold tolerance percentage, represented as a value between `0.0` and `1.0`. Default is `0.2`.

  A lower width threshold tolerance of `0.2` (20%) means that a scanned ID must fall within (100 - 20) = 80% of the capture overlay rectangle width.

  <a id="declaration"></a>

  #### Declaration

  Swift

  ```
  public var lowerWidthThresholdTolerance: Float
  ```

  `upperWidthThresholdTolerance`

  Upper ID capture rectangle width threshold tolerance percentage, represented as a value between `0.0` and `1.0`. Default is `0.05`.

  An upper width threshold tolerance of `0.05` (5%) means that a scanned ID must fall within (100 + 5) = 105% of the capture overlay rectangle width.

  #### Declaration

  Swift

  ```
  public var upperWidthThresholdTolerance: Float
