Hi Dave
I don't think there's much I can add as far as QTRgui. Any specific limitations are due to the
language and libraries it was written with. Seems strange that the larger compressed file works better
but I can't look into it all all. I've not had anyone talk about limit problems with it before though.
There are a couple things you can do that may help. Use grayscale rather than RGB, convert to
8-bit for printing, rotate image ahead of time rather than have QTR driver do it.
On the Mac side I have more control and info. Again its mostly dependent on system limits - hardware and software.
There have been a couple cases where people went over the 2G limit of 32 bits and this caused
some internal problems. But that is huge.

More information after some further testing:
Print-Tool on the Mac can open both files with no problems. So this is clearly only a problem on Windows using QTRGui. My feeling at this point is that QTRGui is running into some kind of internal memory management issue when opening large TIF files. But I'd still like to know if there is any kind of "documented" (but maybe not largely known) limit on the maximum TIF file size in either QTRGui or Print-Tool.
Roy, any comments?
Thanks,
Dave
