Correct.

I think you mean the C library?  (That is, OpenSlide itself, rather than 
one of its bindings.)  If so, you'll want to use the main API functions:

openslide_get_level_count()
openslide_get_level0_dimensions()
openslide_get_level_dimensions()
openslide_get_level_downsample()
openslide_get_best_level_for_downsample()
openslide_read_region()

rather than the ones for associated images.
