When Run Code:

        RenderTexture* pRender = RenderTexture::create(
            static_cast<int>(tmpSprite->getContentSize().width),
            static_cast<int>(tmpSprite->getContentSize().height),
            backend::PixelFormat::RGBA8888);

//        pRender->setSprite(tmpSprite);
        pRender->begin();
        tmpSprite->visit();
        pRender->end();

        pRender->newImage([role](Image* image) {
            auto polygon = ImageAutoPolygon::generatePolygon(image);
            role->initWithPolygon(polygon);
            // role->updatePoly();
            role->setVisible(true);
        });

In line
auto polygon = ImageAutoPolygon::generatePolygon(image);
You Will get a incomplete Image Instance
Because Image::_data is null data
