Android Image Cropper

Powerful (Zoom, Rotation, Multi-Source), customizable (Shape, Limits, Style), optimized (Async, Sampling, Matrix) and simple image cropping library for Android.

Usage

For a working implementation, please have a look at the Sample Project

See GitHub Wiki for more info.

Include the library

compile 'com.theartofdev.edmodo:android-image-cropper:2.2.+'

Using Activity

2. Add CropImageActivity into your AndroidManifest.xml

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"/>

3. Start CropImageActivity using builder pattern from your activity

CropImage.activity(imageUri)
   .setGuidelines(CropImageView.Guidelines.ON)
   .start(this);

4. Override onActivityResult method in your activity to get crop result

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        CropImage.ActivityResult result = CropImage.getActivityResult(data);
        if (resultCode == RESULT_OK) {
            Uri resultUri = result.getUri();
        } else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            Exception error = result.getError();
        }
    }
}

Using View

2. Add CropImageView into your activity

<!-- Image Cropper fill the remaining available height -->
<com.theartofdev.edmodo.cropper.CropImageView
   xmlns:custom="http://schemas.android.com/apk/res-auto"
   android:id="@+id/cropImageView"
   android:layout_width="match_parent"
   android:layout_height="0dp"
   android:layout_weight="1"/>

3. Set image to crop

cropImageView.setImageBitmap(bitmap);
// or
cropImageView.setImageUriAsync(uri);

4. Get cropped image

Bitmap cropped = cropImageView.getCroppedImage();
// or (must subscribe to async event using cropImageView.setOnGetCroppedImageCompleteListener(listener))
cropImageView.getCroppedImageAsync();
