I have wrote a program with C++ and VIDE to make 8 or 16 bit height 
feilds from contour lines. It for win98.

It's at http://leroywhetstone.s5.com/

I used PPM to save the 16 bit height feilds ,TGA for 8 bit height feilds 
and BMP for the contour maps files . I hand coded the PPM & TGA file 
functions and use windows functions for BMP.

If the program doesn't do what you need E-mail me and I can send you the 
code. It might be a little messy and if you don't have VIDE you may 
still be able to figure it out.
