Image processing debugging with ddd

Dear GNU team,
I am developing some (computationaly intensive) nuclear medical imaging applications in C language. I use the gcc compiler and gdb/ddd on a Linux platform to debug. I have seen that ddd have some nice 2D/3D visualizing capabilities using gnuplot as a helper. The problem is that working with image processing applications you usually want to see 2D arrays as a grey intensity map image( I think gnuplot cannot do that but maybe I am wrong ) As you guess, I would like to watch some array variable and see how it is changing while I am debugging. Any comments/suggestions/information on how to do that would be more than welcome.
Best regards,
PD.- Please, I would thank you to reply to this email adress as I am not subscribed to the ddd list
