POSet xy position to a imageView using faceDetection
text
Body
copied!<p>I am detecting a face in my app. I use two ImageView, the first for the face and the second for a mask. I need set the mask position over the calculated face position and then can move the mask with touch event. For the touch event I did use of this tutorial: <a href="http://blahti.wordpress.com/2011/01/17/moving-views-part-2/" rel="nofollow">http://blahti.wordpress.com/2011/01/17/moving-views-part-2/</a></p> <p>The method for mask scalling can return the face position. I tried set the XY position to the mask Imageview but ever is showed in the position 0.0. over the face. Then I can move the mask ImageView over the face. "view" is my mask. Ideally I need initialize the mask imageview over the face position.</p> <p>PD: Sorry my english is bad.</p> <pre><code>protected Bitmap draw(int mode) { Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.c10); int width = bitmap.getWidth(); int height = bitmap.getHeight(); Point position = new Point(); xRatio = anchoCara * 1.0f / anchoCara; yRatio = altoCara * 1.0f / altoCara; Bitmap resizedBitmap = null; float factor = 9.6f;//9.6 for (int i = 0; i < eyesMidPts.length; i++) { if (eyesMidPts[i] != null) { pOuterBullsEye.setStrokeWidth(eyesDistance[i] / 6); float newWidth = eyesDistance[i] * factor; float newHeight = eyesDistance[i] * factor; float scaleWidth = (newWidth) / width; float scaleHeight = (newHeight) / height; Matrix matrix = new Matrix(); matrix.postScale(scaleWidth, scaleHeight); resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true); position.set( (int) ((eyesMidPts[i].x * xRatio) - (eyesDistance[i] * factor) ),//2 (int) ((eyesMidPts[i].y * yRatio) - (eyesDistance[i] * factor) )); Log.e("Face", "positio x : " + position.x); Log.e("Face", "positio y : " + position.y); Log.e("Face", "mascara width : " + resizedBitmap.getWidth()); Log.e("Face", "mascara heigth : " + resizedBitmap.getHeight()); // view.setBackgroundDrawable(new BitmapDrawable(resizedBitmap)); // view.setAdjustViewBounds(true); // Log.i("Face", "positio x : " + view.getScrollX()); // Log.i("Face", "positio y : " + view.getScrollY()); } } return resizedBitmap; } </code></pre>
