Remarks
If this annotation contains text, and has been added to a rotated page, the text in the annotation may be rotated. If RefreshAppearance is called *after* the annotation is added to a rotated page, then any text will be rotated in the opposite direction of the page rotation. If this method is called *before* the annotation is added to any rotated page, then no counter rotation will be applied. If you wish to call RefreshAppearance on an annotation already added to a rotated page, but you don't want the text to be rotated, you can do one of the following; temporarily un-rotate the page, or, temporarily remove the "Rotate" object from the annotation. To support users adding text annotations while using a PDF viewer, you can also add any viewer rotation to the annotations Rotate object, to have text always rotated correctly, from the users perspective.
