Remarks

pageMode can be one of the following:
ModeDescription
AnnCodecsSavePageMode.OverwriteThe stream will be overwritten and all previous information will be lost. The value of page must be 1 or -1 (if appending the objects as the last page).
AnnCodecsSavePageMode.InsertThe stream must have valid annotation objects saved to it. The value of page must be between 1 and the total number of pages in the stream. A value of -1 will append the objects as the last page.
AnnCodecsSavePageMode.ReplaceThe stream must have valid annotation objects saved to it. The value of page must be between 1 and total number of pages in the stream.

This method will not position the stream back to its original position before it returns. It is your responsibility to position the stream back before you can load objects from this stream.

Requirements

Target Platforms: Microsoft .NET Framework 2.0, Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family
