Remarks

You cannot have a RasterImage with no pages, therefore, an exception will occur if you attempt to remove the only page left in a RasterImage object

This method pulls the pages from startIndex to startIndex + count and appends it at the end of the pages list of this RasterImage object. The number of pages in this image is decremented by count.

The RasterImage object can hold multiple pages with different sizes. The AddPage, AddPages, InsertPage and InsertPages methods allows adding new pages to an existing RasterImage.

The RemovePageAt, RemovePages and RemoveAllPages methods allows removing existing pages from a RasterImage object.

The ReplacePage and ReplacePages methods allows replace existing pages in a RasterImage object.

The PageCount property holds the total number of pages in a RasterImage object while the Page property allows you to change the current active page.

The current active page (The page indicated by the Page property) is used by default when accessing the data of a RasterImage object unless otherwise indicated.
