设置文本生成标志 （.NET）

文本生成标志指定文本是向后显示还是倒置显示。使用该属性可以定义文本样式是控制要向后显示的文本的显示还是倒置显示，或者使用文本对象的 and 属性来单独控制文本对象。FlagBitsIsMirroredInXIsMirroredInY

如果希望向后显示文本，请设置为 2，如果要倒置显示文本，请设置为 4。使用值 6 向后和上下显示文本。如果要修改文本对象，请设置为“如果希望文本向后显示”，如果希望将其倒置显示，请设置为“TRUE”。FlagBitsIsMirroredInXTRUEIsMirroredInY

向后显示文本

下面的示例创建一个单行文本对象，然后使用该属性将其设置为向后显示。IsMirroredInX
