在ImageView的特定XY点上的图像上添加图像

我有一个女性形象。我使用FaceDetector找到了她的视点。现在我想用这些眼睛点将头发图像添加到她的脸上。在ImageView的特定XY点上的图像上添加图像

我使用以下代码加载从图库该图像

btnLoad.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     Intent intent = new Intent(); 
     intent.setType("image/*"); 
     intent.setAction(Intent.ACTION_GET_CONTENT); 
     intent.addCategory(Intent.CATEGORY_OPENABLE); 
     startActivityForResult(intent, RQS_LOADIMAGE); 
    } 
});

在onActivityResult，我检查面部cordinates

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    try { 
     InputStream inputStream = getContentResolver().openInputStream(data.getData()); 
     myBitmap = BitmapFactory.decodeStream(inputStream); 
     inputStream.close(); 
     imgView.setImageBitmap(myBitmap); 

     if (myBitmap == null) { 
      Toast.makeText(MainActivity.this, "myBitmap == null", Toast.LENGTH_LONG).show(); 
     } else { 
      detectFace(); 
     } 
    } catch (IOException e) { 
     e.printStackTrace(); 
    } 
}

面部检测方法

private void detectFace() { 

    Paint myRectPaint = new Paint(); 
    myRectPaint.setStrokeWidth(5); 
    myRectPaint.setColor(Color.RED); 
    myRectPaint.setStyle(Paint.Style.STROKE); 

    tempBitmap = Bitmap.createBitmap(myBitmap.getWidth(), myBitmap.getHeight(), Bitmap.Config.RGB_565); 
    Canvas tempCanvas = new Canvas(tempBitmap); 
    tempCanvas.drawBitmap(myBitmap, 0, 0, null); 

    FaceDetector faceDetector = new FaceDetector.Builder(this) 
      .setTrackingEnabled(true) 
      .setLandmarkType(FaceDetector.ALL_LANDMARKS) 
      .setMode(FaceDetector.ACCURATE_MODE) 
      .setClassificationType(FaceDetector.ALL_CLASSIFICATIONS) 
      .build(); 

    Frame frame = new Frame.Builder().setBitmap(myBitmap).build(); 
    SparseArray<Face> faces = faceDetector.detect(frame); 

    imgView.setImageDrawable(new BitmapDrawable(getResources(), drawOnFace(faces))); 
}

获取眼坐标使用下面的代码： -

private Bitmap drawOnFace(SparseArray<Face> faceArray) { 

    tempBitmap = Bitmap.createBitmap(myBitmap.getWidth(), myBitmap.getHeight(), Bitmap.Config.RGB_565); 
    Canvas canvas = new Canvas(tempBitmap); 
    canvas.drawBitmap(myBitmap, 0, 0, null); 

    for (int i = 0; i < faceArray.size(); i++) { 

     Face face = faceArray.get(i); 

     for (Landmark landmark : face.getLandmarks()) { 
      switch (landmark.getType()) { 
       case Landmark.LEFT_EYE: 
        drawPoint(canvas, landmark.getPosition()); 
        break; 
       case Landmark.RIGHT_EYE: 
        drawPoint(canvas, landmark.getPosition()); 
        break; 
      } 
     } 
    } 
    return tempBitmap; 
}

抽奖圈在使用下面的代码的眼睛： -

private void drawPoint(Canvas canvas, PointF point) { 

    Paint paint = new Paint(); 
    paint.setColor(Color.RED); 
    paint.setStrokeWidth(8); 
    paint.setStyle(Paint.Style.STROKE); 

    float x = point.x; 
    float y = point.y; 

    canvas.drawCircle(x, y, 10, paint); 
}

现在DrawPoint方法里面，我有眼坐标。我想用这些点将头发图像放在脸上。我真的不知道接下来该做什么。感谢帮助的人。预先感谢您

任何运气吗？ – Redman

对此问题没有任何解决方案 – Mahesh

我想出了如何将图像放在相机预览上，但图像未放置在正确的位置 – Redman

要放置在摄像头预览图像使用此代码

float left=0,top=0; 
Bitmap bitmap= BitmapFactory.decodeResource(getResources(),R.drawable.mustache); 
//if you are in non activity then use context.getResources() 
canvas.drawBitmap(bitmap,left,top,paint);
