"inverted" NineSlicePlane

[meiciuc]

Good day!
Please, give me an idea, how to achieve an effect like "inverted" NineSlicePlane - (center non scaled).
Thanks.

Copy source of NineSlicePlane, implement different kind of scaling

Thanks, I even know about inheritance! But I do not understand a work with vertices.

        const scale = this._getMinScale();

        vertices[9] = vertices[11] = vertices[13] = vertices[15] = this._topHeight * scale;
        vertices[17] = vertices[19] = vertices[21] = vertices[23] = this._height - (this._bottomHeight * scale);
        vertices[25] = vertices[27] = vertices[29] = vertices[31] = this._height;
