ProgressTimer type BAR

I have created a progress timer (Type bar) .I have a created a scale9sprite and set its content size to visible width.
I am using the same image file for both progress timer and scale9sprite. I want my progress timer to start from left to visible width. But my progress start from left to image width how can i do that.My sample code is -

 float Abc::showTimeLeft(float height)
{
    auto m_timeoutSprite=cocos2d::ui::Scale9Sprite::create("Sweep_result_white_bg.png");
    m_visibleSize=Director::getInstance()->getVisibleSize();
    auto label=Label::createWithSystemFont("NEW ROUND WILL START IN",
                                              UIImagePaths::DEFAULT_FONT_NAME(),22);
    m_timeoutSprite->setContentSize(cocos2d::Size(m_visibleSize.width,label->getBoundingBox().size.height*2));
    
    auto yPos=height-m_timeoutSprite->getBoundingBox().size.height;
    m_timeoutSprite->setPosition(cocos2d::Vec2(m_visibleSize.width/2,yPos));
    this->addChild(m_timeoutSprite);
    schedule(schedule_selector(Abc::::newRoundTimeLabelUpdate), 1.0);             //here i am updating the percentage of progress Timer
    auto  m_timeOutProgressTimer = ProgressTimer::create(Sprite::create("Sweep_result_white_bg.png"));
    if (m_timeOutProgressTimer != nullptr )
    {
        m_timeOutProgressTimer->setType(ProgressTimer::Type::BAR);
        m_timeOutProgressTimer->setMidpoint(Vec2(0, 0.5));
        m_timeOutProgressTimer->setBarChangeRate(Vec2(1, 0));
        m_timeOutProgressTimer->setPercentage(0);
        m_timeOutProgressTimer->setColor(cocos2d::Color3B::GREEN);
        m_timeOutProgressTimer->setContentSize(Size(m_timeoutSprite->getBoundingBox().size));
        
        m_timeOutProgressTimer->setPosition(Vec2(m_timeoutSprite->getBoundingBox().size.width/2, m_timeoutSprite->getBoundingBox().size.height/2 ));
        m_timeoutSprite->addChild(m_timeOutProgressTimer);
        
    }
    auto x1=m_timeoutSprite->getBoundingBox().size;
    auto x2=m_timeOutProgressTimer->getBoundingBox().size;
    return yPos-m_timeoutSprite->getBoundingBox().size.height;
}
