    Remarks
    On adding pages, checks that the new page is not attached to any other document. The Remove method detaches a page from the document. If it is referenced from anywhere else, it remains a valid stand-alone page.

    The content of the array can only include the pages that correspond with the type of the document. For example, if the page array is a part of ImGearPDFDocument the type of pages should be ImGearPDFPage. The addition of any pages that do not correspond with the document type will cause an exception.

    Well-formed page array may contain any number of null entries. An exception is made for the formats where pages are physically continuous (i.e., PDF). Note that setting a page to null is different from removing a page from the document - the former does not change page count, whereas the latter does.

    Example
    The following example illustrates how to change the order of pages in the document. This way of page array reordering is useful only for ImGearRasterPage because such pages do not support the System.IDisposable interface. For disposable pages like ImGearPDFPage removing pages from an array calls the Dispose() method, and any further page additions to this array will cause System.ObjectDisposedException. To avoid the addition of a disposed page, it should be cloned before pulling it out from the array, and the clone should be inserted in the required position.
