Re: [Openexr-devel] Adding/updating attribute to existing OpenEXR file

[Ken McGaugh]

The exrstdattr tool that comes with openexr does a similar thing, so you 
could look at how it is done there.  In short it does the following:

  InputFile in (inFileName);
  Header header = in.header();
  // insert additional attributes to header here
  OutputFile out (outFileName, header);
  out.copyPixels(in);
