True if characters in the specified WordArt are rotated 90 degrees relative to the WordArt's bounding shape. False if characters in the specified WordArt retain their original orientation relative to the bounding shape. Read/write Long.
Remarks
If the WordArt has horizontal text, setting the RotatedChars property to True rotates the characters 90 degrees counterclockwise. If the WordArt has vertical text, setting the RotatedChars property to False rotates the characters 90 degrees clockwise. Use the ToggleVerticalText method to switch between horizontal and vertical text flow.
The Flip method and Rotation property of the Shape object and the RotatedChars property and ToggleVerticalText method of the TextEffectFormat object all affect the character orientation and direction of text flow in a Shape object that represents WordArt. You may have to experiment to find out how to combine the effects of these properties and methods to get the result you want.
