*** ** * ** ***

A `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo` allows the application to know the resolution information of a specific use case.

Applications can know the resolution information of `https://developer.android.com/reference/kotlin/androidx/camera/core/Preview` before a `https://developer.android.com/reference/kotlin/androidx/camera/core/SurfaceRequest` is received, or know the resolution information of `https://developer.android.com/reference/kotlin/androidx/camera/core/ImageAnalysis` before an `https://developer.android.com/reference/kotlin/androidx/camera/core/ImageProxy` is received from `https://developer.android.com/reference/kotlin/androidx/camera/core/ImageAnalysis.Analyzer`.

## Public constructors

### ResolutionInfo

Added in [1.3.0](https://developer.android.com/jetpack/androidx/releases/camera#1.3.0)

```
ResolutionInfo(resolution: Size, cropRect: Rect, rotationDegrees: Int)
```

Creates a new instance of `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo` with the given parameters. This constructor is not normally needed outside of testing cases.

| Parameters |
|---|---|
| `resolution: https://developer.android.com/reference/android/util/Size.html` | The resolution used for the `https://developer.android.com/reference/kotlin/androidx/camera/core/UseCase` expressed in the coordinates of the camera sensor. |
| `cropRect: https://developer.android.com/reference/android/graphics/Rect.html` | The crop rectangle specifies the region of valid pixels in the buffer. |
| `rotationDegrees: https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The clockwise rotation in degrees that needs to be applied to the output buffer so the image appears upright at the target rotation setting. Value is one of the following: - `0` - `90` - `180` - `270` <br /> |

## Public functions

### equals

```
fun equals(obj: Any?): Boolean
```

### getCropRect

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/camera#1.1.0)

```
fun getCropRect(): Rect
```

Returns the crop rectangle.

The crop rectangle specifies the region of valid pixels in the buffer, using coordinates from `(0, 0)` to the `(width, height)` of the resolution obtained by `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo#getResolution()`. The dimensions need to be flipped by the rotation degrees obtained via `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo#getRotationDegrees()` to match the target rotation setting.

If the use case is configured with a `https://developer.android.com/reference/kotlin/androidx/camera/core/ViewPort`, this value is calculated based on the configuration of `https://developer.android.com/reference/kotlin/androidx/camera/core/ViewPort`; if not, it returns the full rect of the buffer which the dimensions will be the same as the value obtained from `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo#getResolution()`.

### getResolution

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/camera#1.1.0)

```
fun getResolution(): Size
```

Returns the output resolution used for the use case.

The resolution will be expressed in the coordinates of the camera sensor. The dimensions need to be flipped by the rotation degrees obtained via `https://developer.android.com/reference/kotlin/androidx/camera/core/ResolutionInfo#getRotationDegrees()` to match the target rotation setting.

### getRotationDegrees

Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/camera#1.1.0)

```
fun getRotationDegrees(): Int
```

Returns the rotation degrees needed to transform the output resolution to the target rotation.

This is a clockwise rotation in degrees that needs to be applied to the output buffer so the image appears upright at the target rotation setting. The rotation will be determined by the camera sensor orientation value and target rotation setting.

Value is one of the following:

- `0`
- `90`
- `180`
- `270`

<br />

| Returns |
|---|---|
| `https://kotlinlang.org/api/core/kotlin-stdlib/kotlin/-int/index.html` | The rotation in degrees which will be a value in {0, 90, 180, 270}. |

### hashCode

```
fun hashCode(): Int
```

### toString

```
fun toString(): String
```
