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

My solution was this, which maintains aspect ratio, and requires only one size, for example if you have a 1920*1080 and an 1080*1920 image and you want to resize it to 1280, the first will be 1280*720 and the second will be 720*1280

public static Bitmap resizeBitmap(final Bitmap temp, final int size) {
        if (size > 0) {
            int width = temp.getWidth();
            int height = temp.getHeight();
            float ratioBitmap = (float) width / (float) height;
            int finalWidth = size;
            int finalHeight = size;
            if (ratioBitmap < 1) {
                finalWidth = (int) ((float) size * ratioBitmap);
            } else {
                finalHeight = (int) ((float) size / ratioBitmap);
            }
            return Bitmap.createScaledBitmap(temp, finalWidth, finalHeight, true);
        } else {
            return temp;
        }
    }
