Lets say we load a multipage tiff file with 10 pages and we see the 3rd page. How can i know that i see the 3rd page? Is there any way that tells me which page i am viewing at moment? cpav

The BitmapViewer control itself always works with a single instance of Aurigma.GraphicsMill.Bitmap class - it knows nothing about the source of the image. So you should implement this by yourself. Just save somewhere the number of the currently loaded TIFF frame and use it when necessary.

You may just use some class variable for that. We have no such property because BitmapViewer is a really some sort of "universal soldier". This control is used in multiple scenarios and far not all of them include handling multipage formats. Edited by user Tuesday, March 18, 2008 9:05:18 PM(UTC) \| Reason: Not specified

But it would be a nice idea to have a property for this reason, so multipage formats can have its property > =1 and all other formats could be by default =1.
