Class: MxCADMText

2d.MxCADMText

MxCAD 多行文本实体类，用于在 CAD 中渲染、编辑和管理富文本内容。

Description

MxCADMText 是一种自定义多行文本实体，适用于在 MxCAD 场景中展示富文本、自动换行、行高控制、文本对齐和多段落排版。这个类能够完成：

创建和管理多行文本对象的数据与样式；
按指定宽度、行高、对齐方式进行排版；
支持角度、位置、最大宽高等属性的动态更新；
在 worldDraw 阶段将文本内容按元素递归渲染到 CAD 界面；
处理夹点编辑、坐标转换和自定义变换逻辑。

使用方式：

实例化 MxCADMText，并设置 data、position、maxWidth、lineHeightRatio 等属性；
在需要时调用 angle、textAlignment、isWordWrap 等属性更新渲染状态；
通过 worldDraw() 把文本内容绘制到当前图形环境；
调用 customizeTransformBy() 或 transformBy() 完成矩阵变换；
通过 MxCpp.mxcad.drawEntity() 将文本实体绘制到 CAD 界面。

总结：MxCADMText 是 MxCAD 场景中的富文本自定义实体，通常用于需要复杂多行排版、编辑交互和自定义渲染的文本场景。
