Scaled Bitmap maintaining aspect ratio

Question

I would like to scale a Bitmap to a runtime dependant width and height, where the aspect ratio is maintained and the Bitmap fills the entire width

Answer 1

here is a method from my Utils class, that does the job:

public static Bitmap scaleBitmapAndKeepRation(Bitmap targetBmp,int reqHeightInPixels,int reqWidthInPixels)
    {
        Matrix matrix = new Matrix();
        matrix .setRectToRect(new RectF(0, 0, targetBmp.getWidth(), targetBmp.getHeight()), new RectF(0, 0, reqWidthInPixels, reqHeightInPixels), Matrix.ScaleToFit.CENTER);
        Bitmap scaledBitmap = Bitmap.createBitmap(targetBmp, 0, 0, targetBmp.getWidth(), targetBmp.getHeight(), matrix, true);
        return scaledBitmap;
    }
