I created a three-page TIFF image with annotations (using the DotAnnotate Demo).

When I try to load only the second page (frameIndex=1) with the AnnotateViewer Open-Method an Exception is thrown. I tried it with MultipageAnnotateMode = True or False.

What am I missing here?

 MyAnnotateViewer.Open( filename, 1, True )

=>

System.ArgumentOutOfRangeException

Invalid index for this collection.
Parametername: index

Tatsächlicher Wert war 1.   at Atalasoft.Annotate.UI.LayerCollection.Insert(Int32 index, LayerAnnotation layer)

   at Atalasoft.Annotate.UI.Importers.XmpAnnotationImporter.LLImport(Int32 page)
   at Atalasoft.Annotate.UI.Importers.AnnotationImporter.Import(Int32 page)
   at Atalasoft.Annotate.UI.AnnotateViewer.ImportAnnotations(AnnotationImporter importer, Int32 frameIndex)
   at Atalasoft.Annotate.UI.AnnotateViewer.Open(Stream stream, Int32 frameIndex, Boolean loadAnnotations)
   at Atalasoft.Annotate.UI.AnnotateViewer.Open(String fileName, Int32 frameIndex, Boolean loadAnnotations)
 

I've been able to duplicate this.  My guess is that the XmpAnnotationImporter is assuming that all pages and a layer for each page is setup, causing it to error when it tries to access layer index 1.

For now you will have to load all pages with MultipageAnnotateMode set to true.
