Android Image Cropper
=====================
- **Powerful** (Zoom, Rotation, Multi-Source)
- **Customizable** (Shape, Limits, Style)
- **Optimized** (Async, Sampling, Matrix)
- **Simple** image cropping library for Android
## Add to your project
```groovy
dependencies {
implementation("com.vanniktech:android-image-cropper:4.6.0")
}
```
## Using the Library
There are 3 ways of using the library. Check out the sample app for all details.
### [1. Calling crop directly](./sample/src/main/kotlin/com/canhub/cropper/sample/SampleCrop.kt)
**Note:** This way is deprecated and will be removed in future versions. The path forward is to write your own Activity, handle all the `Uri` stuff yourself and use `CropImageView`.
```kotlin
class MainActivity : AppCompatActivity() {
private val cropImage = registerForActivityResult(CropImageContract()) { result ->
if (result.isSuccessful) {
// Use the cropped image URI.
val croppedImageUri = result.uriContent
val croppedImageFilePath = result.getUriFilePath(this) // optional usage
// Process the cropped image URI as needed.
} else {
// An error occurred.
val exception = result.error
// Handle the error.
}
}
private fun startCrop() {
// Start cropping activity with guidelines.
cropImage.launch(
CropImageContractOptions(
cropImageOptions = CropImageOptions(
guidelines = Guidelines.ON
)
)
)
// Start cropping activity with gallery picker only.
cropImage.launch(
CropImageContractOptions(
pickImageContractOptions = PickImageContractOptions(
includeGallery = true,
includeCamera = false
)
)
)
// Start cropping activity for a pre-acquired image with custom settings.
cropImage.launch(
CropImageContractOptions(
uri = imageUri,
cropImageOptions = CropImageOptions(
guidelines = Guidelines.ON,
outputCompressFormat = Bitmap.CompressFormat.PNG
)
)
)
}
// Call the startCrop function when needed.
}
```
### [2. Using CropView](./sample/src/main/kotlin/com/canhub/cropper/sample/SampleUsingImageView.kt)
**Note:** This is the only way forward, add `CropImageView` into your own activity and do whatever you wish. Checkout the sample for more details.
```xml
```
- Set image to crop
```kotlin
cropImageView.setImageUriAsync(uri)
// Or prefer using uri for performance and better user experience.
cropImageView.setImageBitmap(bitmap)
```
- Get cropped image
```kotlin
// Subscribe to async event using cropImageView.setOnCropImageCompleteListener(listener)
cropImageView.getCroppedImageAsync()
// Or.
val cropped: Bitmap = cropImageView.getCroppedImage()
```
### [3. Extend to make a custom activity](./sample/src/main/kotlin/com/canhub/cropper/sample/SampleCustomActivity.kt)
**Note:** This way is also deprecated and will be removed in future versions. The path forward is to write your own Activity, handle all the `Uri` stuff yourself and use `CropImageView`.
If you want to extend the `CropImageActivity` please be aware you will need to set up your `CropImageView`
- Add `CropImageActivity` into your AndroidManifest.xml
```xml
```
- Set up your `CropImageView` after call `super.onCreate(savedInstanceState)`
```kotlin
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setCropImageView(binding.cropImageView)
}
```
#### Custom dialog for image source pick
When calling crop directly the library will prompt a dialog for the user choose between gallery or camera (If you keep both enable).
We use the Android default AlertDialog for this. If you wanna customised it with your app theme you need to override the method `showImageSourceDialog(..)` when extending the activity _(above)_
```kotlin
override fun showImageSourceDialog(openSource: (Source) -> Unit) {
super.showImageSourceDialog(openCamera)
}
```
