Class Line

java.lang.Object

org.ofdrw.layout.element.Div<Canvas>

org.ofdrw.layout.element.canvas.Canvas

org.ofdrw.layout.element.canvas.CanvasBase

org.ofdrw.layout.element.canvas.Line

All Implemented Interfaces:

Drawer, ElementSplit, RenderPrepare

public class Line
extends CanvasBase

OFDRW 线条元素，用于快速构建一条线条。

若需要绘制复杂图形，请使用 Canvas 对象，并提供 Drawer实现，在Drawer中使用绘制上下文绘制。

若绘制简单矩形，可以使用 Div 对象设置边框 实现。
