title: Re-size Image maintaining Aspect Ratio
body: <p>I am attempting to re-size an image and maintain its aspect ratio the bitmap mBitmap measures 1200x539 and I need to reduce this to about 1/3rd of that.</p>
  
  <pre><code> mBitmap =  Bitmap.createBitmap (mContent.getWidth(), mContent.getHeight(), Bitmap.Config.RGB_565);;
  
                  int H = (int)mBitmap.getHeight();      
                  int W =(int)mBitmap.getWidth();            
                  nBitmap = BitmapScaler.setBitmapScale(mBitmap, W,H);
  </code></pre>
  
  <p>I spotted this answer provided by Streets Of Boston and have attempted to use it in my app but I may have messed up the variables and I am getting a blank image the same size as the original,  can anyone show me how to achieve this correctly?</p>

  <p>The code runs without error but returns an image the same size as the original!</p>
  
  <pre><code>public static Bitmap setBitmapScale(Bitmap originalImage, int width, int height){
  
              Bitmap background = Bitmap.createBitmap((int)width, (int)height, Config.ARGB_8888);
              float originalWidth = originalImage.getWidth(), originalHeight = originalImage.getHeight();
              Canvas canvas = new Canvas(background);
              float scale = width/originalWidth;
              float xTranslation = 0.0f, yTranslation = (height - originalHeight * scale)/2.0f;
              Matrix transformation = new Matrix();
              transformation.postTranslate(xTranslation, yTranslation);
              transformation.preScale(scale, scale);
              Paint paint = new Paint();
              paint.setFilterBitmap(true);
              canvas.drawBitmap(originalImage, transformation, paint);
              return background;
        }
