Failed to get correct layer count for Aperio images

[Ginger Han]

Hello,

I have a collection of Aperio whole slide images of digital pathology. None of them was successfully read using OpenSlide C API functions. 

For example, with openslide_get_level_count()  I only get -1 for layer count indicating that the reading was not right.

However, ALL of them can be opened using Aperio ImageScope without any problem.

Please help!!!!
