Java
Image Cropping Library for Android, optimized for Camera / Gallery.

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

1. Add CropImageActivity into your AndroidManifest.xml

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

2. Start CropImageActivity using builder pattern from your activity

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

3. 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

1. 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"/>

2. Set image to crop

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

3. Get cropped image

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

Features

• Built-in CropImageActivity.
• Set cropping image as Bitmap, Resource or Android URI (Gallery, Camera, Dropbox, etc.).
• Image rotation during cropping.
• Auto zoom-in/out to relevant cropping area.
• Auto rotate bitmap by image Exif data.
• Set result image min/max limits in pixels.
• Set initial crop window size/location.
• Bitmap memory optimization.
• API Level 10.
• More..

Customizations

• Cropping window shape: Rectangular or Oval (cube/circle by fixing aspect ratio).
• Cropping window aspect ratio: Free, 1:1, 4:3, 16:9 or Custom.
• Guidelines appearance: Off / Always On / Show on Toch.
• Cropping window Border line, border corner and guidelines thickness and color.
• Cropping background color.

For more information, see the GitHub Wiki.

• Android cropping image from camera or gallery
• Android Image Cropper async support and custom progress UI
• Adding auto-zoom feature to Android-Image-Cropper

Change log

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.
