I use this code to get an image from my scanner:

ImageEnView1.IO.Acquire


This works well with one single scanned image.

But the scanner driver interface allows me also to scan multiple images:



However, ImageEnView1.IO.Acquire does not give me back the information how many pages were scanned. If I had that information I could save the multiple scanned pages in a buffer or in a container image file like e.g. TIFF or in a TImageEnMView and then display one of them in ImageEnView1.

So is it possible to get the number of scanned pages?

Multi-page scanning with splitting via barcodes.
I scan in an internal TImageEnView and then forward the scanned images to one or more instances of TImageEnView or TImageEnVect.

In the TImageEnMView.ImageUserPointer, all existing images are marked beforehand, so you can easily find out which the newly scanned images are.

Hi Peter

That's not really practical from within ImageEn (TImageEnIO is attached only to a TImageEnView, whereas TImageEnMVIO is attached only to a TImageEnMView).

However you can do it in your application code without difficulty.

It would be nice if both Single-Page-Scan and Multi-Page-Scan could be done from the same IE routine:

• If the Scan-Result is Single-Page then the scanned image would be viewed in ImageEnView

• Else if the Scan-Result is Multi-Page then the scanned images would be viewed in ImageEnMView

Hi

Sinisa is correct. TImageEnView/TImageEnIO can only be used for single scans. Please use TImageEnMView/TImageEnMIO

Hi,

I use MView->MIO->Acquire() to scan multiple pages in TImageEnMView.
I don't know if single view (TImageEnView) can handle multiple pages.
