Revision history [back]

I use NativeCameraView and want to take pictures with camera resolutions. But I can take pictures only in preview resolution. mRgba.cols() and mRgba.rows() get resolution of display but I want to capture with camera resolution and I want the user to choose camera resolution.

public Mat onCameraFrame(CvCameraViewFrame inputFrame) {
    // TODO Auto-generated method stub

    /*
    mRgba = inputFrame.rgba();
    Imgproc.cvtColor(mRgba, mRgba, Imgproc.COLOR_RGB2HSV_FULL);
    return mRgba;
    */

    // http://answers.opencv.org/question/12265/how-to-display-a-mat-in-imageview/
    if (take_pic)
    {
        take_pic = false;

        mRgba = inputFrame.rgba();
        bitmap = Bitmap.createBitmap(mRgba.cols(), mRgba.rows(),Bitmap.Config.ARGB_8888);
        Utils.matToBitmap(mRgba, bitmap);

        // http://stackoverflow.com/questions/5776684/how-can-i-convert-a-view-to-a-drawable
        //v.setDrawingCacheEnabled(true);
        //bitmap = Bitmap.createBitmap(v.getDrawingCache());

        //Log.i(TAG,"onTouch event");
        SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd_HH-mm-ss");
        String currentDateandTime = sdf.format(new Date());
        String fileName = Environment.getExternalStorageDirectory().getPath() +
                               "/camera" + currentDateandTime + ".jpg";

        //mOpenCvCameraView.takePicture(fileName); //***

        // http://stackoverflow.com/questions/4989182/converting-java-bitmap-to-byte-array
        ByteArrayOutputStream stream = new ByteArrayOutputStream();;
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
        byteArray = stream.toByteArray();

        try {
             FileOutputStream fos = new FileOutputStream(fileName);

             fos.write(byteArray);
             fos.close();

          //mCamera.startPreview();
        } catch (java.io.IOException e) {
          Log.e("PictureDemo", "Exception in photoCallback", e);
        }
          return mRgba;
    }

How can I use display resolution for preview and capture with camera resolution using NativeCameraView?

And how can I find out camera resolutions for NativeCameraView (it hasn't a setResolution method like the JavaCameraView)?
