I have an application which acquires a line scanned Xray Image ( 768 pixels
per 2 ms ).

 I need to provide a windowed or full screen, real time, smoothly scrolling
image. This was relatively easy to do in DOS by changing the graphics
adaptor frame pointer but can a similar approach be used using Delphi/Win32?

Any hardware/software suggestions/references will be most appreciated.

Thanks,
Arthur

Arthur,

If you are acquiring at 500 lines per second, your display is going to be
scrolling off the screen every two seconds (or so).  I would guess at having
a circular buffer into which new lines are written, and using Direct-X to
swap between two display buffers each being filled in the display time of
the other.  You might be able to get 60 frames/second doing that.  Even so,
you would still be scrollling 8 lines between each frame.

Just a first guess!

David
