Hewlett Packard used to give developers a free Twain-compatible scanning library for 16-bit DOS. All I had to do was answer a 5-minute over-the-phone questionnaire. I don't know if they now offer a 32-bit version, or even if they still offer it at all. > TWAIN requires Windows as everything is bundled in DLL's & the header file > requires windows.h Twain is an interface standard and does not require Windows.

Of course, though different approaches are possible for different video modes. You have to decide which approach you want: hardware split screen with mode-x, software control through overlapping bitmaps with software scrolling, software control through stretching bitmaps to fit the given screen, etc. -- Tony O'Bryan http://www.geocities.com/SiliconValley/Park/7201
