A while back I read in the forums that some changes were to be made to the Twain scanning functions, and that this was planned for release 5.1.2. Now that 5.2.0 is out I don't see anything in the change log about Twain enhancements. Did I miss something or have the Twain changes been postponed to a later release?

I am working on porting a project from Skyline's ImageLib to ImageEn and I didn't want to spend too much time on the scanning part if changes were upcoming in ImageEn. If the enhancements are off the table for now I will just go ahead and port the scanning part using the current version.

Thanks.

Hi

5.2.0 (we skipped v5.1.2) includes some enhancements to Twain handling, but nothing that affects the interface:

Also, remember that ImageEn includes a generic TIEAcquireParams class:

Which provides access to devices via Twain, WIA and (in v5.2.1) Windows Portable Devices API, without your needing to consider the underlying API.

I am just starting the process of trying to migrate Twain/Wia functionality from ImageLib to ImageEn. I have just run into my first roadblock.

The old code called
illow_open_twain(Handle);
to retrieve a handle to the twain device.

How do I do this with ImagEn?

Thank you.

Hi Dick

ImageEn does not expose the Twain handle. Why do you use it for?
