title: Moving hotspots i.e View over scaled & panned Image.
body: <p>I have been working on for panning the image in a container for which I am using TouchImageView. What I am trying to achieve is that I
  want to translate some other view with respect to the amount of panning i.e translation made.</p>
  
  <p>Below is the ACTION_MOVE Event when user makes a pan event.</p>
  
  <pre><code>                 case MotionEvent.ACTION_MOVE:
                      if (state == State.DRAG) {
                          float deltaX = curr.x - last.x;
                          float deltaY = curr.y - last.y;
                          float fixTransX = getFixDragTrans(deltaX, viewWidth, getImageWidth());
                          float fixTransY = getFixDragTrans(deltaY, viewHeight, getImageHeight());
  
  
                          matrix.postTranslate(fixTransX, fixTransY);
                          fixTrans();
  
                          // this is my function for callbacks. 
                          // This is where I want to restrict callback if translation values from matrix is 0 after scaling / zooming
                          // but it still gives values &gt; 0 if trying to pan.
                          moveViewsWithSameDistance(fixTransX, fixTransY);
  
                          last.set(curr.x, curr.y);
                      }
                      break;
  </code></pre>
  
  <p>The issue I am facing is all works well while translating the tags over panned image. But when the Image has reached its bounds it still get translationX or translationY  values greater/less than 0 which makes my tags move out of bound.
  Is there any way I can restrict the extra translation.? I have tried with matrix method. I still get the translation values above 0 after I reach its bounds when the image is scaled.</p>
