When images are added/inserted or removed from a RasterImage object, the RasterImage.PagesChanged event will fire with an instance of the RasterImagePagesChangedEventArgs class. This instance contains information on what pages has been changed. The following table will list the methods that would invoke the RasterImage.PagesChanged event and what values are expected.

For the destination image (The this or Me in Visual basic image): Action is RasterImagePagesChangedAction.Added, StartIndex is RasterImage.PageCount since the pages are added at the end and Count is 1. |
| RasterImage.AddPages | For the source image (the image parameter): Action is RasterImagePagesChangedAction.Removed, StartIndex is the value of the startIndex parameter and Count is the value of the count parameter. For the destination image (The this or Me in Visual basic image): Action is RasterImagePagesChangedAction.Added, StartIndex is RasterImage.PageCount since the pages are added at the end and Count is the value of the count parameter. |

For the destination image (The this or Me in Visual basic image): Action is RasterImagePagesChangedAction.Added, StartIndex is the value of the index parameter and Count is 1. |
| RasterImage.InsertPages | For the source image (the image parameter): Action is RasterImagePagesChangedAction.Removed, StartIndex is the value of the startIndex parameter and Count is the value of the count parameter.
