In the pursuit of simplicity, OpenSlide tries to hide the low-level 
format details that a lossless format converter would need.  It is 
intended to be a format reader library, not the input stage of a format 
converter.  Indeed, a driving principle behind the development of 
OpenSlide is that conversions of existing slide data to a common format 
will never, in general, be good enough for archival purposes.

Of the formats supported by OpenSlide, I think only Aperio, Leica, and 
Sakura might be suitable for format conversion without recompression.
