[Openexr-devel] Help implementing Imf::Ostream

[Koraxen]

Hi guys,

I am trying to implement Imf::Ostream. Unfortunately, the EXR manual only shows how to implement Imf::Istream. That being said, please consider this pseudocode:

const char filename[] = "file.exr"

// Case 1:
Imf::OutputFile( filename )

// Case 2:
MyOStream ostr( mySTDostream , filename )
Imf::OutputFile( ostr )

In both cases, files of almost equal sizes are successfully written. 

All EXR viewers can open a file generated by #1. 
All EXR viewers crash when opening a file generated by #2.

Please note that I am constructing MyOStream with an std::ofstream, instead of std::ostream. Does anyone have an example of a working implementation of Imf::Ostream? 

Thanks for reading :)
