GraphicsMagick already includes code to parse an EXIF profile so even the existing libtiff trivial support for unrecognized tags should be sufficient for retrieving/parsing the profile. However, it would be nice to be able to write EXIF profiles as well. If libtiff includes support for the EXIF tag type then it should also know how to write the profile without any heavy-lifting.

Is it believed that libtiff should understand the innards of embedded profiles? It doesn't seem that this is libtiff's style.


I think that libtiff should have a mechanism for reading private non-image IFDs. I don't think it needs to try and interprete the EXIF tag values though.

Does that answer the question?
