Struct CtLayer 

pub struct CtLayer {
    pub id: Option<StId>,
    pub layer_type: Option<String>,
    pub draw_param: Option<StRefId>,
    pub objects: Vec<PageBlock>,
}

CT_Layer：图层（见表 14、表 15）。

图层内部的图元对象（文字/图形/图像/复合对象，见 PageBlock）属于页面 描述（第 8 章起）；它们按出现顺序保存在 objects 中， 供 crate::render 渲染器按叠放次序绘制。

Fields

id: Option<StId>

图层标识。

layer_type: Option<String>

层类型，取值 Body/Foreground/Background，默认 Body（可选）。

draw_param: Option<StRefId>

图层的绘制参数，引用资源文件中定义的绘制参数标识（可选）。

objects: Vec<PageBlock>

图层内的页面图元对象，按文档顺序排列。
