  I was actually planning to contribute this to openslide if I manage to get it working. By examining the tiffdump I was able to see that some of the proprietary (and unlabeled) tag values have interesting proportions suggesting a tiled representation. I'm working to get the spec from Hamamatsu so I can close the loop and get this working.

I already tried using libtiff 4.0.2 to read the header and encountered the same overflow message. From what I can tell TIFFVStripSize still uses 32-bit representation in 4.0.2.

Interesting, I did get tiffinfo from CVS to read the header. Possibly there was some fix there not in the beta, or possibly it was because I compiled it on a 64-bit machine?

P.S.:

Off topic for Tiff list:

For OpenSlide, make sure your documentation has no strings attached, meaning that you can use it for any purpose, including implementing a competing implementation. Otherwise I'm afraid the code wouldn't be acceptable for inclusion in OpenSlide.
