I did that in VB3, reading a machine vision file (gray scale). You can download
the code from this page: http://thelabwiz.home.mindspring.com/vbsource.html

Look for VISION. The ZIP file includes the source, the VB3 executable (needs
the VB3 runtime), and some sample images.

You'll have to adapt the code to the dimensions of your image and the
differences in VB3 and whatever version you're using. The original code works
with a fixed format image of 165 lines of 200 bytes each.

The code can threshold the various values to shift the white/black points in the
grayscale. It also can divide the 256 gray levels into 16 colors representing
the pixels in a given range of values as all the same color: i.e., all the pixel
values from 0-15 might be black, 16-31 blue, etc. The code hasn't been updated
since 1993, so I no longer remember the details.
