##Download
Include the following dependency in your build.gradle file.
repositories {

}
dependencies {
compile 'com.isseiaoki:simplecropview:1.0.14'
}##Image Cropping
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_CONTENTwill be ignored.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<com.isseiaoki.simplecropview.CropImageView
android:id="@+id/cropImageView"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="250dp"
android:padding="16dp"
custom:cropMode="ratio_1_1"
/>
<Button
android:id="@+id/crop_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_margin="16dp"
android:text="CROP"
/>
<ImageView
android:id="@+id/croppedImageView"
android:layout_margin="16dp"
android:layout_gravity="center"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</LinearLayout>Set image, and get cropped image.
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
final ImageView croppedImageView = (ImageView)findViewById(R.id.croppedImageView);
// Set image for cropping
cropImageView.setImageBitmap(BitmapFactory.decodeResource(getResources(), R.mipmap.sample5));
Button cropButton = (Button)findViewById(R.id.crop_button);
cropButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Get cropped image, and show result.
croppedImageView.setImageBitmap(cropImageView.getCroppedBitmap());
}
});
}
}For a working implementation of this project see the simplecropview-sample folder.
##Image Rotation
Code for rotating the image 90 degrees clockwise is followings.
CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.rotateImage(CropImageView.RotateDegrees.ROTATE_90D);You can also use ROTATE_180D and ROTATE_270D.
##Customization
###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);CropMode Values:
RATIO_4_3, RATIO_3_4, RATIO_1_1, RATIO_16_9, RATIO_9_16, RATIO_FIT_IMAGE, RATIO_FREE, CIRCLE(1.0.8~)
>`RATIO_FREE`: *Non-Fixed aspect ratio mode*<br>
`RATIO_X_Y`: *Fixed aspect ratio mode*<br>
`RATIO_FIT_IMAGE`: *Fixed aspect ratio mode. The same aspect ratio as the original photo.*
`CIRCLE`: *Fixed aspect ratio mode. RATIO_1_1 + circle overlay. See [Circle Crop](#circle-crop) section for more details.*
>If you need other aspect ratio, use `setCustomRatio(int ratioX, int ratioY);`
###Circle Crop
```java
CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setCropMode(CropImageView.CropMode.CIRCLE);
You can also use custom:cropMode="circle" in your layout XML.
If you need to show circle overlay but save as a square, your can use
getRectBitmap().(1.0.9~)
###MinimumFrameSize The minimum size of the image cropping frame in dp.
CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setMinFrameSizeInDp(100);
###InitialFrameScale The initial frame size of the image cropping frame. (scale: 0.01 ~ 1.0. The default value is 0.75.)
CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
cropImageView.setInitialFrameScale(1.0f);| scale | Appearance |
|---|---|
| 0.5 |  |
| 0.75 (default) |  |
| 1.0 |  |
You can also use custom:initialFrameScale="1.0" in your layout XML.
###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);ShowMode Values:
SHOW_ALWAYS, NOT_SHOW, SHOW_ON_TOUCH
| Handle ShowMode | Guide ShowMode | Appearance |
|:-------------:|:-------------:|:-----:|
| SHOW_ALWAYS | SHOW_ALWAYS | <img src="https://raw.github.com/wiki/IsseiAoki/SimpleCropView/images/graphic/show_handle_and_guide.jpg" width="100%"> |
| NOT_SHOW | NOT_SHOW | <img src="https://raw.github.com/wiki/IsseiAoki/SimpleCropView/images/graphic/not_show_handle_and_guide.jpg" width="100%"> |
| SHOW_ALWAYS | NOT_SHOW | <img src="https://raw.github.com/wiki/IsseiAoki/SimpleCropView/images/graphic/show_handle_only.jpg" width="100%"> |

| SHOW_ON_TOUCH | NOT_SHOW | <img src="https://raw.github.com/wiki/IsseiAoki/SimpleCropView/images/gif/demo_handle_show_on_touch.gif" width="100%"> |
##Picasso Compatibility
`com.isseiaoki.simplecropview.CropImageView` is a kind of `ImageView`.
You can use it with Picasso as follows.
```java
CropImageView cropImageView = (CropImageView)findViewById(R.id.cropImageView);
Picasso.with(context).load(imageUrl).into(cropImageView);
Some option does not work correctly because CropImageView does not support ImageView.ScaleType.
