Retrieve pixel values from GeoTIFF [message #73791]

I'm trying to get the pixel values (color) from a GeoTIFF file when I
have lat,lon arrays. I have the projection set up using MAP_PROJ_INIT,
and using MAP_PROJ_FORWARD I can convert from my latitude and
longitude to map coordinates, but the map coordinates appear to be in
units meter from some reference location. What is the best routine to
convert from lat,lon (or u,v) to x,y indices?

Thanks,

-k.
