The text generation flag specifies if text is displayed backwards or upside-down. Use the FlagBits property to define if a text style controls the display of text to be displayed backwards or upside-down, or use the IsMirroredInX and IsMirroredInY properties of a text object to control individually control a text object.
文字生成标志指定文字是否要反向或倒置显示。使用 FlagBits 属性定义文字样式是否控制文字的反向或倒置显示，或使用文字对象的 IsMirroredInX 和 IsMirroredInY 属性单个的控制文字对象。
Set FlagBits to 2 if you want text to be displayed backwards and 4 if it should be displayed upside-down. Use a value of 6 to display text both backwards and upside-down. If you are modifying a text object, set IsMirroredInX to TRUE if you want the text to appear backwards and set IsMirroredInY to TRUE if you want it to be displayed upside-down.
如果想文字显示为反向，请设置 FlagBits 为2，如果设置为4将倒置显示文字。使用值6，文字将显示为反向和倒置。如果修改文字对象，如果想文字显示为反向的，请将 IsMirroredInX 设置为 True，而如果想文字倒置显示，请将 IsMirroredInY 设置为 True。
The following example creates a single-line text object, then sets it to be displayed backwards using the IsMirroredInX property.
本例创建一个单选文本对象，然后利用 IsMirroredInX 属性设置它反向显示。
