Deletes a page from an annotation file containing multiple pages.
fileName
Name of the annotation file.
page
Number of the page to delete. The page number is 1-based. Therefore, the first page is page 1, the second page is page 2, etc.
This method can be used to remove annotation pages from a multi-page annotation file. The page number is 1-based. Therefore, the first page is page 1, the second page is page 2, and so on. This method can be used for all LEAD annotation file formats. To determine the format for a particular LEAD annotation file, use GetInformation(string,anncodecsinformation).
Note, you cannot delete a page from an annotation file that has only 1 page.
