private void drawSun(Canvas canvas, float pct) {

    // calculate the center point of the sun image

    Rect sunBounds = mSunImage.getBounds();

    x -= sunBounds.width() / 2;/*from   www .  j  ava 2s.  c  o m*/
    y -= sunBounds.height() / 2;

    // if we are in rtl, we still want to show the image normally
    // so flip it back
    canvas.translate(x, y);
    if (mIsRtl) {
        canvas.save();
        canvas.scale(-1, 1, sunBounds.centerX(), sunBounds.centerY());

    // restore the flip again
