[Openexr-devel] Per Tile "Header-like" storage?

[Axel Waggershauser]

Hi,

I would like to store some additional information per image tile in an 
OpenEXR image. Maybe something like the attributes in the header. To be 
a bit more specific, I'd like to store a digital signature per tile.

Is this possible with the current implementation? If not (that's what I 
guess at the moment), would the internal structure "support" an 
extention for this kind of, possibly variable length, additional 
information storage per tile? Or would this have to go in a one "huge" 
attribute into the header?


Thanks,
  Axel
