    hi everybody. i’m currently developing a twain data source and it works fine in native mode so far. now i’m working on the buffered memory part and it works fine with most of the software i tested it with. unfortunatly, some programs set up the transfer and memory buffer correct and my source transfers the image data, but when look at the copied picture it is completly messed up. adjusting the zoom factor of the application the viewer can at least get a guess of what the picture is showing. please get a look at these screenshots, maybe you’ll have some hints for me?

    the original photo:

    now what my twain ds made of it:

    how i set the imageinfo part:

    any ideas?

    thx for reading.
