##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_show_mode="show_always"
    custom:scv_min_frame_size="50dp"
    custom:scv_frame_stroke_weight="1dp"
    custom:scv_guide_stroke_weight="1dp"/>

Load image from sourceUri.

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

mCropView.startLoad(

    sourceUri,
    
    new LoadCallback() {
        @Override
        public void onSuccess() {}

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

Crop image and save cropped bitmap in saveUri.

mCropView.startCrop(

    saveUri,
    
    new CropCallback() {
        @Override
        public void onSuccess(Bitmap cropped) {}

        @Override
        public void onError() {}
    },
    
    new SaveCallback() {
        @Override
        public void onSuccess(Uri outputUri) {}

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

###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

setImageXXX()(Sync method)

This method loads the given Bitmap. If the bitmap size is too large, Exception occurs.

startLoad(Uri sourceUri, LoadCallback callback)(Async method, RECOMMENDED)

This method loads Bitmap in efficient size from sourceUri. You don't have to care for filePath and image size.

REMEMBER : sourceUri parameter will be used in startCrop(Uri saveUri, CropCallback cropCallback, SaveCallback saveCallback).

##Crop and Save Image

getCroppedBitmap()(Sync method)

This method always use thumbnail bitmap set by setImageXXX() for cropping. It does not save cropped bitmap.

startCrop(Uri saveUri, CropCallback cropCallback, SaveCallback saveCallback)(Async Method, RECOMMENDED)

This method uses full size bitmap taken from sourceUri for cropping. If sourceUri is not set, it uses thumbnail bitmap. 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);

demo

####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);

demo

###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)

###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);
