Imagining Software



Does anyone know of a software package (Windows based preferably) that can
 that
 a graphic file that represents 3-D on a 2-D image (color coded contour for
 example) and generate a 2-D, graph of that data a certain point.   This would
 involve drawing a line across the picture and the program generating an x vs. y
 graph for the data points on that line.  If I could find a program that could
 convert a color-coded .tiff into x,y,z coordinates, I could import the data to
 Excel and accomplish the same thing.  What is desired is to generate x vs. y.
 graphs from a "3-D" picture (represented as a color coded .tiff image)
 by
 selecting different segments of the .tiff image.
 Thanks in advance,
