I fixed it.This needs to be changed to the following code.

  osg::ref_ptr<osg::Vec3Array> quad_coords = new osg::Vec3Array; // vertex 
coords
    // counter-clockwise
    quad_coords->push_back(osg::Vec3d(0, 0, -1));
    quad_coords->push_back(osg::Vec3d(tex_width, 0, -1));
    quad_coords->push_back(osg::Vec3d(tex_width, tex_height, -1));
    quad_coords->push_back(osg::Vec3d(0, tex_height, -1));

    osg::ref_ptr<osg::Vec2Array> quad_tcoords = new osg::Vec2Array; // 
texture coords
    quad_tcoords->push_back(osg::Vec2(0, 0));
    quad_tcoords->push_back(osg::Vec2(tex_width, 0));
    quad_tcoords->push_back(osg::Vec2(tex_width, tex_height));
    quad_tcoords->push_back(osg::Vec2(0, tex_height));在此输入代码...
