言论

连接点指定插入点与文本边界对齐的位置。您选择的选项确定相对于文本边界的文本对齐和文本溢出。文本对齐的选项包括“左”、“右”和“居中”。文本溢出的选项包括“顶部”、“中间（中间）”和“底部”。

左上角 左对齐，溢出	顶部中心 居中对齐，向下溢出	右上 右对齐，溢出
左中 左对齐，上下溢出	中中心 居中对齐，上下溢出	右中 右对齐，上下溢出
左下角 左对齐，溢出	底部中心 居中对齐，溢出	右下角 正确对齐，溢出

更改属性时，现有边界框的位置不会更改;文本只是在边界框中重新对齐。但是，属性反映正在使用的连接点的坐标，因此属性的值将更改以反映对齐方式的变化。AttachmentPointInsertionPointInsertionPoint
