Does anyone have experience with gray scale images with MS Windows.

I am trying to display a 16 level gray scale image within a Windows
application.  I am using a VGA compatible card (ATI VIP). If I retrieve
the screen display context and create a compatible bitmap, the bitmap is
in the following form:

red scan 0..n-1
green scan 0..n-1
blue scan 0..n-1

where n is the height of the image in raster lines.


Pixels in a scanline are represented by one bit per colour.
The problem with this arrangement is that only eight colours can be specified.
I want to use the full 16 available with the VGA standard.

Thanks in advance.
