Powerbuilder WebCam

Question

I am using EZTWAIN from a powerbuilder application to acquire images from an HP scanner. Recently I tried a Kodak model (i1120) and it seems that it is not supported. Specifically the application freezes during the scanning process (perhaps the problem has to do with duplex scanning).

Can you recommend another library that you have used and works ok for you, and provides an easy-to-use wrapper for the TWAIN API that can be used from Powerbuilder?

Answer 1

Check out this company: http://www.data-tech.com/ we use their ImageMan ActiveX suite with PB 10.5 and it works without a problem.

Answer 2

I had a similar problem with duplex scanning with several libraries. The solution is to use the scanner's interface directly when using duplex scanning instead of the ActiveX component. Most of the libraries have an option that can be enabled on the fly to use the scanner interface.

I currently use the Viscomsoft Scanner Pro ActiveX library.
