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:2.1.+'

Using Activity

Add CropImageActivity into your AndroidManifest.xml

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

Start CropImageActivity using builder pattern from your activity

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

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

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"/>

Set image to crop

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

Get cropped image

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

Features

Set cropping image as Bitmap, Resource or Android URI (Gallery, Camera, Dropbox, etc.).

Set initial crop window size/location.
Bitmap memory optimization.
API Level 10.

Cropping window aspect ratio: Free, 1:1, 4:3, 16:9 or Custom.

Change log

2.1.4

Support for requesting CAMERA permission for android M when CAMERA is requested in the manifest.
Add pick_image_intent_chooser_title for changing and localizing pick image chooser title (thx maksymkhar).
NPE when clicking crop twice fast (thx Jesse).

2.1.1

Built-in CropImageActivity for quick start and common scenarios.
Save cropped image to Uri API saveCroppedImageAsync(Uri).
Handle possible out-of-memory in image load by down-sampling until succeed.
Minor fixes.

2.0.1 (Beta)

Fix counter clockwise rotation resulting in negative degrees (#54).

2.0.0 (Beta)

Auto-zoom: zoom-in when crop window takes less than 50% of the image, zoom-out when more than 65%.
Handle cropping of non-straight angles rotations for URI loaded images.
Improve performance for image rotation.
Improve performance for rotation due to exif orientation data.
Improve performance for orientation change.
Preserve crop window on rotations for straight angles - 90/180/270.
Preserve crop window on orientation change.
Handle max allowed texture size on device by down-sampling to be within the limit.
API breaking changes:
Renamed CropImageHelper to CropImage
Removed getActualCropRect() and getActualCropRectNoRotation(), replaced by 'getCropPoints()' and 'getCropRect()'.
Moved to custom CropImageView.ScaleType for 'setScaleType()'
Removed CropShape from getCroppedImage API, added CropImage.toOvalBitmap.
Known issues:
Boundaries and orientation change for non-straight angle rotation of images.
