The Handling Multiframe Images demo found here shows how to handle multiframe tiff file pages: https://www.imageen.com/ieforum/topic.asp?TOPIC_ID=1446&whichpage=2. You just need to add the code to fill ImageEnMView with pages from your scanner. The code to rotate is already in the demo, so just add a button and the code to sharpen the frame.
Once the pages have been added to ImageEnMView just select SaveAs to save all the images in the ImageEnMView to a tiff file in the above demo.
The demo will display each page when you select a frame in ImageEnMView. Once all the frames are rotated and sharpened just select the SaveAs button to save all the frames multipage TIFF file.
You do not have to save any scanned images to a file until you save all the frames with save to file.
