Hello,

I am trying to read tags of type double from tiff images that were created on a PC. I'm trying to read the tags with version 3.6.1 of LIBTiff on a Strong-Arm processor running Linux.

Unfortunately - I am getting garbage from the tags. I'm assuming this is an issue with different floating point standards. Actually, the strong arm processor does not have a floating point processor - so we are using a floating point emulator (nwfpe) that, at this point, I know very little about. I do know that the emulator is supposed to be using IEEE floating point standard (similar to PC).

I'll also note that I'm able to read the tags just fine with LIBTiff on the PC, and, I'm able to read all other tags (longs, shorts and ASCIIs) on the Strong-ARM box without problems as well.

So - the question - Has anyone dealt with this cross platform conundrum before? Any thoughts on how to get this to work?

Thanks,
Alan
