类 CanvasBase

java.lang.Object

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

org.ofdrw.layout.element.canvas.Canvas

org.ofdrw.layout.element.canvas.CanvasBase

所有已实现的接口:

Drawer, ElementSplit, RenderPrepare

直接已知子类:

ArtWord, Line

public abstract class CanvasBase
extends Canvas
implements Drawer

Canvas扩展基类，用于快速构建基于Canvas扩展的自定义元素。

通过CanvasBase类，可以简化Canvas的创建过程，实现者需要实现 Drawer 接口， 并在Drawer.draw(DrawContext) 实现自定义的绘制逻辑。

一个最简单扩展示例可参考 Line。
