Hi

What method do you use to retrieve the "fast scan preview"?

You can use the AcquireFrame* properties to select an area to acquire:

Hello Nigel, i get a fast preview scanning at 72dpi, then i would get the selected frame rescanning @ 300dpi.
Thanks for suggesting me the AcquireFrame function.
Now i just need to wrtie some math to convert pixels coords @72dpi to inches (frame) @300dpi.

Thank you
