Hi!
I hope I didn't misunderstand your question, but this should work:
import OpenImageIO as oiio
buf = oiio.ImageBuf('/path/to/imagefile.exr')
buf.specmod().attribute('MyAttribute', 'my value')
buf.write('/path/to/modified/imagefile.exr')
Please note:
I'm not sure you can avoid writing the whole file even if you overwrite the
original.
However creating an ImageBuf this way doesn't read the pixel data until
write time or manipulated through ImageBufAlgo for instance.
