Hi Battle and others,
Some inevitable history to start this reply.
In April/May/June 2009 I worked on patched tiff libraries for enblend/enfuse
to overcome the 4GB limit for tiffs on OSX. I brought some of these binaries
in the open for testing and a dutch profesional photographer (nickname
Jannes), making huge panos, has tested these builds. At that moment there
were problems with big images (tiff, jpg, png) having horizontal and
vertical lines in them and that patched tiff development road stopped more
or less. It doesn't make sense to create 4+ GB tiffs as the tiffs below that
limit already are unusable for another reason.
Second, and for me most important reason, was that my MacBook was fried
early July 2009 (which most users of this community might remember) and I
decided to go back to (cheap) Linux which I had used for many years (since
1993 partly and since 2000 completely until 2007). However, after 2 months I
decided to buy a Mac again as nothing can beat the MacOSX (this despite the
fact that I hate all the semi-religional, apple-protectionism marketing spam
from prophet Steve Jobs).
This 4GB+ panos are only for the very few among us. For me it's not a
priority at all especially as I won't use them myself (and you may call that
selfish). Now that I have built the several enblend/enfuse versions I might
as well build another 64bit tiff patched enblend/enfuse in the near future.
I don't promise anything, maybe I will.
Hoi,
Harry

Does anyone know how the file compression works in hugin. TIFs are
limited to 4GB, but there are compression options in hugin -- LZW,
deflate, packbits. They yield pretty good compressions around 50 to
75% reduction. Does this reduction happen prior of the final image
TIF assembly, or after. In other words if I'm generating a a 3gb tiff
uncompressed and it ends up as 1GB, can I safely triple the size of
the panorama or will that cause problems because the final output tif
is generated first and then compressed. In this example that would be
a 9GB uncompressed over double the limit before compression.
And in a related question if I switched to PNG or JPG ouput, when are
those files generated and does this get me past the 4GB TIF file size
limit?
Thanks
Battle
