Using TWAIN with GFL SDK

Post by Kossman »

I would like to acquire images from a TWAIN source (scanner) and use the GFL SDK to view/edit and save the image as a multi-page TIFF.
Does anyone use or know of a TWAIN control or DLL that works well with this SDK, or have any other suggestions?

At present I use the Victor Image Processing Library in VB to acquire and save the image, but it doesn't support 4-bit grayscale, and the bitmap structure it uses doesn't seem to be easily converted to the GFL SDK bitmap structure.

What platform are you using?

Is this for Windows, or some other platform?

I'm using Windows and VB6.0 at the moment, but may use VB.Net later.

MS Paint and MS Photo Editor both allow for TWAIN acqusition. I've been looking for an API for either of those, but no info yet...

I have used Visionary Solutions toolset (http://www.visolu.com), though they do have a runtime license fee.
