Example

Image Cropping

Add permission in AndroidManifest.xml file.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

Add the com.isseiaoki.simplecropview.CropImageView to your layout XML file.

NOTE: The image is scaled to fit the size of the view by maintaining the aspect ratio. WRAP_CONTENT will be ignored.

<com.isseiaoki.simplecropview.CropImageView
    xmlns:custom="http://schemas.android.com/apk/res-auto"
    android:id="@+id/cropImageView"
    android:layout_weight="1"
    android:paddingTop="16dp"
    android:paddingBottom="16dp"
    android:paddingLeft="16dp"
    android:paddingRight="16dp"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    custom:scv_crop_mode="fit_image"
    custom:scv_background_color="@color/windowBackground"
    custom:scv_handle_color="@color/colorAccent"
    custom:scv_guide_color="@color/colorAccent"
    custom:scv_overlay_color="@color/overlay"
    custom:scv_frame_color="@color/colorAccent"
    custom:scv_handle_size="14dp"
    custom:scv_touch_padding="8dp"
    custom:scv_handle_show_mode="show_always"

    custom:scv_guide_stroke_weight="1dp"/>

Load image from sourceUri.

mCropView = (CropImageView) findViewById(R.id.cropImageView);

mCropView.load(sourceUri).execute(mLoadCallback);

with RxJava,

mCropView.load(sourceUri).executeAsCompletable();

Crop image and save cropped bitmap in saveUri.

mCropView.crop(sourceUri)
    .execute(new CropCallback() {
  @Override public void onSuccess(Bitmap cropped) {
    mCropView.save(cropped)
        .execute(saveUri, mSaveCallback);
  }

  @Override public void onError(Throwable e) {
  }
});

with RxJava,

mCropView.crop(sourceUri)
    .executeAsSingle()
    .flatMap(new Function<Bitmap, SingleSource<Uri>>() {
      @Override public SingleSource<Uri> apply(@io.reactivex.annotations.NonNull Bitmap bitmap)
              throws Exception {
        return mCropView.save(bitmap)
            .executeAsSingle(saveUri);
      }
    })
    .subscribeOn(Schedulers.newThread())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(new Consumer<Uri>() {
      @Override public void accept(@io.reactivex.annotations.NonNull Uri uri) throws Exception {
        // on success
      }
    }, new Consumer<Throwable>() {
      @Override public void accept(@io.reactivex.annotations.NonNull Throwable throwable)
              throws Exception {
        // on error
      }
    });

Image Rotation

SimpleCropView supports rotation by 90 degrees.

cropImageView.rotateImage(CropImageView.RotateDegrees.ROTATE_90D); // rotate clockwise by 90 degrees
cropImageView.rotateImage(CropImageView.RotateDegrees.ROTATE_M90D); // rotate counter-clockwise by 90 degrees

For a working implementation of this project, see sample project.

Load Image

  • load(sourceUri).execute(mLoadCallback);

with RxJava,

  • load(sourceUri).executeAsCompletable();

These method load Bitmap in efficient size from sourceUri. You don't have to care for filePath and image size. You can also use Picasso or Glide.

Apply Thumbnail

You can use blurred image for placeholder.

mCropView.load(result.getData())
         .useThumbnail(true)
         .execute(mLoadCallback);

Crop and Save Image

mCropView.crop(sourceUri)
    .execute(new CropCallback() {
  @Override public void onSuccess(Bitmap cropped) {
    mCropView.save(cropped)
        .execute(saveUri, mSaveCallback);
  }

  @Override public void onError(Throwable e) {
  }
});

with RxJava,

mCropView.crop(sourceUri)
    .executeAsSingle()
    .flatMap(new Function<Bitmap, SingleSource<Uri>>() {
      @Override public SingleSource<Uri> apply(@io.reactivex.annotations.NonNull Bitmap bitmap)
              throws Exception {
        return mCropView.save(bitmap)
                .executeAsSingle(saveUri);
      }
    })
    .subscribeOn(Schedulers.newThread())
    .observeOn(AndroidSchedulers.mainThread())
    .subscribe(new Consumer<Uri>() {
      @Override public void accept(@io.reactivex.annotations.NonNull Uri uri) throws Exception {
        // on success
      }
    }, new Consumer<Throwable>() {
      @Override public void accept(@io.reactivex.annotations.NonNull Throwable throwable)
              throws Exception {
        // on error
      }
    });

These cropping method use full size bitmap taken from sourceUri for cropping. If sourceUri is null, the Uri set in load(Uri) is used. After cropping, it saves cropped image in saveUri.

Compress Format

You can use 3 compress format, PNG(default), JPEG, and WEBP.

setCompressFormat(Bitmap.CompressFormat.JPEG);

Compress Quality

You can also set compress quality. 0~ 100(default)

setCompressQuality(90);

Customization

Maximum Output Size

You can set max size for output image. The output image will be scaled within given rect.

setOutputMaxSize(300, 300);

Fixed Output Size

You can also set fixed output width/height.

setOutputWidth(100); // If cropped image size is 400x200, output size is 100x50
setOutputHeight(100); // If cropped image size is 400x200, output size is 200x100

CropMode

The option for the aspect ratio of the image cropping frame.

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setCropMode(CropImageView.CropMode.RATIO_16_9);

Values

FIT_IMAGE, RATIO_4_3, RATIO_3_4, SQUARE(default), RATIO_16_9, RATIO_9_16, FREE, CUSTOM, CIRCLE, CIRCLE_SQUARE

Rect Crop

FREE: Non-Fixed aspect ratio mode RATIO_X_Y, SQUARE: Fixed aspect ratio mode FIT_IMAGE: Fixed aspect ratio mode. The same aspect ratio as the original photo.

If you need other aspect ratio, use setCustomRatio(int ratioX, int ratioY);

Circle Crop

CIRCLE: Fixed aspect ratio mode. Crop image as circle. CIRCLE_SQUARE: Fixed aspect ratio mode. Show guide circle, but save as square.( getRectBitmap() is removed.)

MinimumFrameSize

The minimum size of the image cropping frame in dp.(default:50)

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setMinFrameSizeInDp(100);

InitialFrameScale

The initial frame size of the image cropping frame. 0.01~ 1.0(default)

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setInitialFrameScale(1.0f);
scale Appearance
0.5
0.75
1.0 (default)

Save and Restore FrameRect

You can save and restore frame rect as follows. See sample project for more details.

  • Save FrameRect
mCropView.getActualCropRect()
  • Restore FrameRect
mCropView.load(result.getData())
         .initialFrameRect(mFrameRect)
         .execute(mLoadCallback);

Color

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setBackgroundColor(0xFFFFFFFB);
cropImageView.setOverlayColor(0xAA1C1C1C);
cropImageView.setFrameColor(getResources().getColor(R.color.frame));
cropImageView.setHandleColor(getResources().getColor(R.color.handle));
cropImageView.setGuideColor(getResources().getColor(R.color.guide));

Stroke Weight and Handle Size

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setFrameStrokeWeightInDp(1);
cropImageView.setGuideStrokeWeightInDp(1);
cropImageView.setHandleSizeInDp(getResources().getDimension(R.dimen.handle_size));

Handle Touch Padding

Additional touch area for the image cropping frame handle.

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setTouchPadding(16);

Handle and Guide ShowMode

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setHandleShowMode(CropImageView.ShowMode.SHOW_ALWAYS);
cropImageView.setGuideShowMode(CropImageView.ShowMode.SHOW_ON_TOUCH);

Values

SHOW_ALWAYS(default), NOT_SHOW, SHOW_ON_TOUCH
Handle ShowMode Guide ShowMode Appearance
SHOW_ALWAYS SHOW_ALWAYS
NOT_SHOW NOT_SHOW
SHOW_ALWAYS NOT_SHOW
SHOW_ALWAYS SHOW_ON_TOUCH
SHOW_ON_TOUCH NOT_SHOW

Animation

SimpleCropView supports rotate animation and frame change animation.

Enabled

Toggle whether to animate. true is default.

setAnimationEnabled(true);

Duration

Set animation duration in milliseconds. 100 is default.

setAnimationDuration(200);

Interpolator

Set interpolator of animation. DecelerateInterpolator is default. You can also use your custom interpolator.

setInterpolator(new AccelerateDecelerateInterpolator());

Picasso and Glide Compatibility

com.isseiaoki.simplecropview.CropImageView is a kind of ImageView. You can use it with Picasso or Glide as follows:

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
Picasso.with(context).load(imageUrl).into(cropImageView);

or

CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
Glide.with(context).load(imageUrl).into(cropImageView);

Some option does not work correctly because CropImageView does not support ImageView.ScaleType.

Debug

You can use debug display.

setDebug(true);
