How to crop a rectangle from an image in android

Cropping to anything other than a square shape is not possible using the built-in Android cropping handling (com.android.camera.action.CROP).

Look at the OP's reply in the next thread - and you might have a solution.

This thread also has some good suggestions:

• How to select and crop an image in android?

Solution 2:

Just add the following lines of code for aspect ratio 0.75

intent.putExtra("aspectX", 3);
intent.putExtra("aspectY", 4);

and set scale to true.

this should solve the problem.

Solution 3:

It might be little late to answer, considering that the other people might come to this thread with this same question.

cropIntent.putExtra("aspectX", 1);
cropIntent.putExtra("aspectY", 1);

will make sure that you always get a rectangle.

Solution 4:

Selecting a image from gallery and cropping keeping Aspect Ratio wanted. In this case the ratio is BANNER_WIDTH_PX:BANNER_HEIGHT_PX.

   protectedvoidstartSelectorBanner(){
        IntentphotoPickerIntent=newIntent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            photoPickerIntent.setType("image/*");
            photoPickerIntent.putExtra("crop", "true");
             photoPickerIntent.putExtra("aspectX",BANNER_WIDTH_PX);  
             photoPickerIntent.putExtra("aspectY",BANNER_HEIGHT_PX);  
             photoPickerIntent.putExtra("outputX",BANNER_WIDTH_PX);  
             photoPickerIntent.putExtra("outputY",BANNER_HEIGHT_PX);  
            photoPickerIntent.putExtra("return-data", true);
            photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
            startActivityForResult(photoPickerIntent, REQ_CODE_PICK_BANNER);        
  }

            getMainActivity().removeOnActivityResultsListeners(EditQcardFragment.this);
