gd provides lower-level interfaces than the netpbm programs do (and apparently higher level interfaces than libnetpbm). gd is more cumbersome for tasks that pipelines of netpbm programs can handle, but gd is also more powerful. It's straightforward to create images for which you control the value of every pixel.

I've found gd particularly useful for programmatically generating custom graphs. For example:
