Twain library available?

[Mr_Gee]

The question has been asked before (here) but it was more an "how to"
I would like to know if there is twain library available for B4P?

I'd like to be able to control my scanner from within an application..

Here is someone who made a .Net twain image scanner
CodeProject: .NET TWAIN image scanner. Free source code and programming help
I've attached the source, just in case

Is this something that can be used?

Cheers

This isn't Twain, it's WIA. I've tried it with a scanner and a camera. It's a first cut effort, jpg only. See what you think.

Thanks Agraham, it looks awesome

I'll let you know once I've had a chance to test

On my desktop the Twain driver for my Epson scanner has a lot more control than the WIA driver so here's a Twain library. The WIA drivers are also available through Twain.

There may be a memory leak associated with converting DIB bitmaps returned by Twain to .NET Bitmaps. If there is I haven't a clue how to stop it as I am pretty ignorant about native code graphics and memory allocation. EDIT - Sorted for the release version(I think!).
