CT_Layer

Struct CT_Layer 

Source
pub struct CT_Layer {
    pub layer_type: LayerType,
    pub draw_param: Option<u32>,
    pub block: CT_PageBlock,
}
Expand description

对应 Java: org.ofdrw.core.basicStructure.pageObj.layer.CT_Layer

图层类型,用于描述页面中的不同层(正文层、前景层、背景层)。 继承自 CT_PageBlock,增加了图层类型和绘制参数引用。 对应 GB/T 33190-2016 第 7.7 节。

Fields§

§layer_type: LayerType

图层类型。

§draw_param: Option<u32>

绘制参数引用 ID(可选)。

§block: CT_PageBlock

页面块内容。
