Cropping an image in android

Question

I am using the takePicture function in the Camera to continuously take and store pictures on a tablet. I need to know how I can crop the data that is stored upon calling takePicture. Or, if that is not possible, then I need to know how I can read in an image and then use something else to crop it. So far the only solutions I've found to this problem require opening another app to crop. Any help is appreciated.

Answer 1

From the Below Code you will get correct Idea. sometimes you will get Problems if the device is like Samsung Galaxy S3 and you wants to crop image after capturing as they are returning null intent after capturing image.

After spending hours on this issue i finally make it work by Below Way if some one is having this problem in future.

public class MainActivity extends Activity {
    private Uri mImageCaptureUri;

You can try below code to crop the image:

final String Path = "sdcard/test.jpg";
 Bitmap bitmap = BitmapFactory.decodeFile(Path);
 ivSign.setImageBitmap(Bitmap.createScaledBitmap(bitmap, 150, 150, true));
 Intent cropIntent = new Intent("com.android.camera.action.CROP");
 // indicate image type and Uri
 cropIntent.setDataAndType(Uri.fromFile(new File(Path)), "image/*");
 // set crop properties
 cropIntent.putExtra("crop", "true");
 // indicate aspect of desired crop
 cropIntent.putExtra("aspectX", 1);
 cropIntent.putExtra("aspectY", 1);
 // indicate output X and Y
 cropIntent.putExtra("outputX", 256);
 cropIntent.putExtra("outputY", 256);
 // retrieve data on return
 cropIntent.putExtra("return-data", true);
 // start the activity - we handle returning in onActivityResult
 startActivityForResult(cropIntent, 1);
