Hi Thomas,

Have you tried using vips to make the pyramids? It's quite commonly used to make pyramids for iipsrv and friends.

There's a windows binary built against libtiff4 here:

http://www.vips.ecs.soton.ac.uk/supported/7.24/win32/

You need vips-dev-tiff4-7.24.5.zip. If I run this on my laptop with:

$ time vips.exe im_copy bigger8.v bigger.tif:,tile,pyramid,,,,8 > build.log

real    11m35.835s
user    0m40.080s
sys     0m49.710s

I get a 9gb tif pyramid and it seems to work OK. You'll need a program that can read huge tiff pyramids as well, of course.

Documentation for the strange tiff format string here:

http://www.vips.ecs.soton.ac.uk/supported/7.24/doc/html/libvips/VipsFormat.html#im-vips2tiff

Leave the ",,,8" off the end of the string and it'll write smalltiff, though of course your filesizes will be limited.
