Type	Condition
PDFNetException	PDFNetException the PDFNet exception

RefreshAppearance()

Regenerates the appearance stream for the annotation. This method can be used to auto-generate the annotation appearance after creating or modifying the annotation without providing an explicit appearance or setting the "NeedAppearances" flag in the AcroForm dictionary.

Declaration

public void RefreshAppearance()

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.

Exceptions

Type	Condition
PDFNetException	PDFNetException the PDFNet exception
