an empty page…
but what is an empty page? Does an image count as empty if it is all white or all black?
I don’t believe that there are any twain api solutions to this, but I think there are several general image programing solutions. Maybe the closest thing to a twain solution is in extImageInfo and i don’t think you’re looking for that info.
The first nonTWAIN solution that comes to mind is to calculate the image’s histogram – if there is only one color present I’d you’re holding an image that i guess you could consider empty.
