    I’ve recently built a TWAIN DS which wraps our company’s scanner driver based on the sample provided in the TWAIN toolkit. It works fine in the test app as well as several image programs however it has some weird behaviour in photoshop.

    Photoshop leaves my DS window open to scan another image. This is fine, but when I transfer this second image, it appears all white in adobe (although the size and other image parameters are correct). The only image that works is the first one.

    I’ve dumped my memory to disc and the image was how it was supposed to appear so I’m at a loss. Any ideas what could cause such a thing? We purposefully chose as few TWAIN features as possible so the resolution is set to -1 (indeterminate) and the units are pixel only. Any help would be greatly greatly appreciated.
