[Openexr-devel] tellg() throws an exception on large files: OpenEXR V1.4.0a - VS2005

[Michael Wolf]

Hello everybody,

I've got a problem reading a large, tiled openEXR file (that I could write 
perfectly - line order: RANDOM_Y).

The exception Iex::EinvalExc is thrown after a call of _is->seekg(3730400304) 
in Imf::StdIFStream::seekg().

The size of the file is 4.058.791.693 bytes, so just below a potential 4GB 
limit (which by itself would surprise me).

And just to rule everything else out, the file is of course on an NTFS 
partition.

Has anybody encountered a similar problem?

Any help is appreciated - I'll write my own custom level I/O class next to be 
sure of what's happening here.

Thanks and Cheers,

Mike
